app/testpmd: add flex item commands
Network port hardware is shipped with fixed number of
supported network protocols. If application must work with a
protocol that is not included in the port hardware by default, it
can try to add the new protocol to port hardware.
Flex item or flex parser is port infrastructure that allows
application to add support for a custom network header and
offload flows to match the header elements.
Application must complete the following tasks to create a flow
rule that matches custom header:
1. Create flow item object in port hardware.
Application must provide custom header configuration to PMD.
PMD will use that configuration to create flex item object in
port hardware.
2. Create flex patterns to match. Flex pattern has a spec and a mask
components, like a regular flow item. Combined together, spec and mask
can target unique data sequence or a number of data sequences in the
custom header.
Flex patterns of the same flex item can have different lengths.
Flex pattern is identified by unique handler value.
3. Create a flow rule with a flex flow item that references
flow pattern.
Testpmd flex CLI commands are:
testpmd> flow flex_item create <port> <flex_id> <filename>
testpmd> set flex_pattern <pattern_id> \
spec <spec data> mask <mask data>
testpmd> set flex_pattern <pattern_id> is <spec_data>
testpmd> flow create <port> ... \
/ flex item is <flex_id> pattern is <pattern_id> / ...
The patch works with the jansson library API.
A new optional dependency on jansson library is added for
testpmd. If jansson not detected the flex item functionality
is disabled.

ethdev: introduce configurable flexible item
1. Introduction and Retrospective
Nowadays the networks are evolving fast and wide, the network
structures are getting more and more complicated, the new
application areas are emerging. To address these challenges
the new network protocols are continuously being developed,
considered by technical communities, adopted by industry and,
eventually implemented in hardware and software. The DPDK
framework follows the common trends and if we bother
to glance at the RTE Flow API header we see the multiple
new items were introduced during the last years since
the initial release.
The new protocol adoption and implementation process is
not straightforward and takes time, the new protocol passes
development, consideration, adoption, and implementation
phases. The industry tries to mitigate and address the
forthcoming network protocols, for example, many hardware
vendors are implementing flexible and configurable network
protocol parsers. As DPDK developers, could we anticipate
the near future in the same fashion and introduce the similar
flexibility in RTE Flow API?
Let's check what we already have merged in our project, and
we see the nice raw item (rte_flow_item_raw). At the first
glance, it looks superior and we can try to implement a flow
matching on the header of some relatively new tunnel protocol,
say on the GENEVE header with variable length options. And,
under further consideration, we run into the raw item
limitations:
- only fixed size network header can be represented
- the entire network header pattern of fixed format
(header field offsets are fixed) must be provided
- the search for patterns is not robust (the wrong matches
might be triggered), and actually is not supported
by existing PMDs
- no explicitly specified relations with preceding
and following items
- no tunnel hint support
As the result, implementing the support for tunnel protocols
like aforementioned GENEVE with variable extra protocol option
with flow raw item becomes very complicated and would require
multiple flows and multiple raw items chained in the same
flow (by the way, there is no support found for chained raw
items in implemented drivers).
This RFC introduces the dedicated flex item (rte_flow_item_flex)
to handle matches with existing and new network protocol headers
in a unified fashion.
2. Flex Item Life Cycle
Let's assume there are the requirements to support the new
network protocol with RTE Flows. What is given within protocol
specification:
- header format
- header length, (can be variable, depending on options)
- potential presence of extra options following or included
in the header the header
- the relations with preceding protocols. For example,
the GENEVE follows UDP, eCPRI can follow either UDP
or L2 header
- the relations with following protocols. For example,
the next layer after tunnel header can be L2 or L3
- whether the new protocol is a tunnel and the header
is a splitting point between outer and inner layers
The supposed way to operate with flex item:
- application defines the header structures according to
protocol specification
- application calls rte_flow_flex_item_create() with desired
configuration according to the protocol specification, it
creates the flex item object over specified ethernet device
and prepares PMD and underlying hardware to handle flex
item. On item creation call PMD backing the specified
ethernet device returns the opaque handle identifying
the object has been created
- application uses the rte_flow_item_flex with obtained handle
in the flows, the values/masks to match with fields in the
header are specified in the flex item per flow as for regular
items (except that pattern buffer combines all fields)
- flows with flex items match with packets in a regular fashion,
the values and masks for the new protocol header match are
taken from the flex items in the flows
- application destroys flows with flex items
- application calls rte_flow_flex_item_release() as part of
ethernet device API and destroys the flex item object in
PMD and releases the engaged hardware resources
3. Flex Item Structure
The flex item structure is intended to be used as part of the flow
pattern like regular RTE flow items and provides the mask and
value to match with fields of the protocol item was configured
for.
struct rte_flow_item_flex {
void *handle;
uint32_t length;
const uint8_t* pattern;
};
The handle is some opaque object maintained on per device basis
by underlying driver.
The protocol header fields are considered as bit fields, all
offsets and widths are expressed in bits. The pattern is the
buffer containing the bit concatenation of all the fields
presented at item configuration time, in the same order and
same amount. If byte boundary alignment is needed an application
can use a dummy type field, this is just some kind of gap filler.
The length field specifies the pattern buffer length in bytes
and is needed to allow rte_flow_copy() operations. The approach
of multiple pattern pointers and lengths (per field) was
considered and found clumsy - it seems to be much suitable for
the application to maintain the single structure within the
single pattern buffer.
4. Flex Item Configuration
The flex item configuration consists of the following parts:
- header field descriptors:
- next header
- next protocol
- sample to match
- input link descriptors
- output link descriptors
The field descriptors tell the driver and hardware what data should
be extracted from the packet and then control the packet handling
in the flow engine. Besides this, sample fields can be presented
to match with patterns in the flows. Each field is a bit pattern.
It has width, offset from the header beginning, mode of offset
calculation, and offset related parameters.
The next header field is special, no data are actually taken
from the packet, but its offset is used as a pointer to the next
header in the packet, in other words the next header offset
specifies the size of the header being parsed by flex item.
There is one more special field - next protocol, it specifies
where the next protocol identifier is contained and packet data
sampled from this field will be used to determine the next
protocol header type to continue packet parsing. The next
protocol field is like eth_type field in MAC2, or proto field
in IPv4/v6 headers.
The sample fields are used to represent the data be sampled
from the packet and then matched with established flows.
There are several methods supposed to calculate field offset
in runtime depending on configuration and packet content:
- FIELD_MODE_FIXED - fixed offset. The bit offset from
header beginning is permanent and defined by field_base
configuration parameter.
- FIELD_MODE_OFFSET - the field bit offset is extracted
from other header field (indirect offset field). The
resulting field offset to match is calculated from as:
field_base + (*offset_base & offset_mask) << offset_shift
This mode is useful to sample some extra options following
the main header with field containing main header length.
Also, this mode can be used to calculate offset to the
next protocol header, for example - IPv4 header contains
the 4-bit field with IPv4 header length expressed in dwords.
One more example - this mode would allow us to skip GENEVE
header variable length options.
- FIELD_MODE_BITMASK - the field bit offset is extracted
from other header field (indirect offset field), the latter
is considered as bitmask containing some number of one bits,
the resulting field offset to match is calculated as:
field_base + bitcount(*offset_base & offset_mask) << offset_shift
This mode would be useful to skip the GTP header and its
extra options with specified flags.
- FIELD_MODE_DUMMY - dummy field, optionally used for byte
boundary alignment in pattern. Pattern mask and data are
ignored in the match. All configuration parameters besides
field size and offset are ignored.
Note: "*" - means the indirect field offset is calculated
and actual data are extracted from the packet by this
offset (like data are fetched by pointer *p from memory).
The offset mode list can be extended by vendors according to
hardware supported options.
The input link configuration section tells the driver after
what protocols and at what conditions the flex item can follow.
Input link specified the preceding header pattern, for example
for GENEVE it can be UDP item specifying match on destination
port with value 6081. The flex item can follow multiple header
types and multiple input links should be specified. At flow
creation time the item with one of the input link types should
precede the flex item and driver will select the correct flex
item settings, depending on the actual flow pattern.
The output link configuration section tells the driver how
to continue packet parsing after the flex item protocol.
If multiple protocols can follow the flex item header the
flex item should contain the field with the next protocol
identifier and the parsing will be continued depending
on the data contained in this field in the actual packet.
The flex item fields can participate in RSS hash calculation,
the dedicated flag is present in the field description to specify
what fields should be provided for hashing.
5. Flex Item Chaining
If there are multiple protocols supposed to be supported with
flex items in chained fashion - two or more flex items within
the same flow and these ones might be neighbors in the pattern,
it means the flex items are mutual referencing. In this case,
the item that occurred first should be created with empty
output link list or with the list including existing items,
and then the second flex item should be created referencing
the first flex item as input arc, drivers should adjust
the item configuration.
Also, the hardware resources used by flex items to handle
the packet can be limited. If there are multiple flex items
that are supposed to be used within the same flow it would
be nice to provide some hint for the driver that these two
or more flex items are intended for simultaneous usage.
The fields of items should be assigned with hint indices
and these indices from two or more flex items supposed
to be provided within the same flow should be the same
as well. In other words, the field hint index specifies
the group of fields that can be matched simultaneously
within a single flow. If hint indices are specified,
the driver will try to engage not overlapping hardware
resources and provide independent handling of the field
groups with unique indices. If the hint index is zero
the driver assigns resources on its own.
6. Example of New Protocol Handling
Let's suppose we have the requirements to handle the new tunnel
protocol that follows UDP header with destination port 0xFADE
and is followed by MAC header. Let the new protocol header format
be like this:
struct new_protocol_header {
rte_be32 header_length; /* length in dwords, including options */
rte_be32 specific0; /* some protocol data, no intention */
rte_be32 specific1; /* to match in flows on these fields */
rte_be32 crucial; /* data of interest, match is needed */
rte_be32 options[0]; /* optional protocol data, variable length */
};
The supposed flex item configuration:
struct rte_flow_item_flex_field field0 = {
.field_mode = FIELD_MODE_DUMMY, /* Affects match pattern only */
.field_size = 96, /* three dwords from the beginning */
};
struct rte_flow_item_flex_field field1 = {
.field_mode = FIELD_MODE_FIXED,
.field_size = 32, /* Field size is one dword */
.field_base = 96, /* Skip three dwords from the beginning */
};
struct rte_flow_item_udp spec0 = {
.hdr = {
.dst_port = RTE_BE16(0xFADE),
}
};

net/mlx5: fix RSS expansion for L2/L3 VXLAN
The RSS expansion algorithm is using a graph to find the possible
expansion paths. The current implementation does not differentiate
between standard (L2) VXLAN and L3 VXLAN. As result the flow is expanded
with all possible paths.
For example:
testpmd> flow create... / vxlan / end actions rss level 2 / end
It is currently expanded to the following paths:
ETH IPV4 UDP VXLAN END
ETH IPV4 UDP VXLAN ETH IPV4 END
ETH IPV4 UDP VXLAN ETH IPV6 END
ETH IPV4 UDP VXLAN IPV4 END
ETH IPV4 UDP VXLAN IPV6 END
The fix is to adjust the expansion according to the outer UDP destination
port. In case flow pattern defines a match on the standard udp port, 4789,
or does not define a match on the destination port, which also implies
setting the standard one, the expansion for the above example will be:
ETH IPV4 UDP VXLAN END
ETH IPV4 UDP VXLAN ETH IPV4 END
ETH IPV4 UDP VXLAN ETH IPV6 END
Otherwise, the expansion will be:
ETH IPV4 UDP VXLAN END

net/i40e: fix risk in descriptor read in NEON Rx
Rx descriptor is 16B/32B in size. If the DD bit is set, it indicates
that the rest of the descriptor words have valid values. Hence, the
word containing DD bit must be read first before reading the rest of
the descriptor words.
In NEON vector PMD, vector load loads two contiguous 8B of
descriptor data into vector register. Given vector load ensures no
16B atomicity, read of the word that includes DD field could be
reordered after read of other words. In this case, some words could
contain invalid data.
Read barrier is added after read of qword1 that includes DD field.
And qword0 is reloaded to update vector register. This ensures

net/ena: check missing Tx completions
In some cases Tx descriptors may be uncompleted by the HW and as a
result they will never be released.
This patch adds checking for the missing Tx completions to the ENA timer
service, so in order to use this feature, the application must call the
function rte_timer_manage().
Missing Tx completion reset threshold is determined dynamically, by
taking into consideration ring size and the default value.
Tx cleanup is associated with the Tx burst function. As DPDK
applications can call Tx burst function dynamically, time when last
cleanup was called must be traced to avoid false detection of the
missing Tx completion.

ENA can't be forced to always pass single descriptor for the Rx packet.
Even if the passed buffer size is big enough to hold the data, we can't
make assumption that the HW won't use extra descriptor because of
internal optimizations. This assumption may be true, but only for some
of the FW revisions, which may differ depending on the used AWS instance

As the scattered Rx support on the Rx path already exists, the driver

The caller can pass Tx or Rx free threshold value to the configuration
structure for each ring. It determines when the Tx/Rx function should
start cleaning up/refilling the descriptors. ENA was ignoring this value
and doing it's own calculations.
Now the user can configure ENA's behavior using this parameter and if
this variable won't be set, the ENA will continue with the old behavior
and will use it's own threshold value.
The default value is not provided by the ENA in the ena_infos_get(), as
it's being determined dynamically, depending on the requested ring size.
Note that NULL check for Tx conf was removed from the function
ena_tx_queue_setup(), as at this place the configuration will be
either provided by the user or the default config will be used and it's
handled by the upper (rte_ethdev) layer.
Tx threshold shouldn't be used for the Tx cleanup budget as it can be

Enabling jumbo frame offload implicitly is selected by many drivers

ethdev: fix max Rx packet length
There is a confusion on setting max Rx packet length, this patch aims to
clarify it.
'rte_eth_dev_configure()' API accepts max Rx packet size via
'uint32_t max_rx_pkt_len' field of the config struct 'struct
rte_eth_conf'.
Also 'rte_eth_dev_set_mtu()' API can be used to set the MTU, and result
stored into '(struct rte_eth_dev)->data->mtu'.
These two APIs are related but they work in a disconnected way, they
store the set values in different variables which makes hard to figure
out which one to use, also having two different method for a related
functionality is confusing for the users.
Other issues causing confusion is:
* maximum transmission unit (MTU) is payload of the Ethernet frame. And
'max_rx_pkt_len' is the size of the Ethernet frame. Difference is
Ethernet frame overhead, and this overhead may be different from
device to device based on what device supports, like VLAN and QinQ.
* 'max_rx_pkt_len' is only valid when application requested jumbo frame,
which adds additional confusion and some APIs and PMDs already
discards this documented behavior.
* For the jumbo frame enabled case, 'max_rx_pkt_len' is an mandatory
field, this adds configuration complexity for application.
As solution, both APIs gets MTU as parameter, and both saves the result
in same variable '(struct rte_eth_dev)->data->mtu'. For this
'max_rx_pkt_len' updated as 'mtu', and it is always valid independent
from jumbo frame.
For 'rte_eth_dev_configure()', 'dev->data->dev_conf.rxmode.mtu' is user
request and it should be used only within configure function and result
should be stored to '(struct rte_eth_dev)->data->mtu'. After that point
both application and PMD uses MTU from this variable.
When application doesn't provide an MTU during 'rte_eth_dev_configure()'
default 'RTE_ETHER_MTU' value is used.
Additional clarification done on scattered Rx configuration, in
relation to MTU and Rx buffer size.
MTU is used to configure the device for physical Rx/Tx size limitation,
Rx buffer is where to store Rx packets, many PMDs use mbuf data buffer
size as Rx buffer size.
PMDs compare MTU against Rx buffer size to decide enabling scattered Rx
or not. If scattered Rx is not supported by device, MTU bigger than Rx
buffer size should fail.

Also simplified the loop since a modern C compiler can speed up (i.e.
