net/iavf: deprecate i40evf PMD
The i40evf PMD will be deprecated, iavf will be the only VF driver for
Intel 700 serial (i40e) NIC family.
To reach this, there will be 2 steps:
Step 1: iavf will be the default VF driver, while i40evf still can be
selected by devarg: "driver=i40evf".
This is covered by this patch, which include:
1) add all 700 serial NIC VF device ID into iavf PMD
2) skip probe if devargs contain "driver=i40evf" in iavf
3) continue probe if devargs contain "driver=i40evf" in i40evf
Step 2: i40evf and related devarg are removed, this will happen at DPDK
21.11
Between step 1 and step 2, no new feature will be added into i40evf
except bug fix.

Currently, the L3L4P/L3E/L4E/OL3E/OL4E fields in Rx descriptor used to
indicate hardware checksum result:
1. L3L4P: indicates hardware has processed L3L4 checksum for this
packet, if this bit is 1 then L3E/L4E/OL3E/OL4E is trustable.
2. L3E: L3 checksum error indication, 1 means with error.
3. L4E: L4 checksum error indication, 1 means with error.
4. OL3E: outer L3 checksum error indication, 1 means with error.
5. OL4E: outer L4 checksum error indication, 1 means with error.
Driver will set the good checksum flag through packet type and
L3E/L4E/OL3E/OL4E when L3L4P is 1, it runs as follows:
1. If packet type indicates it's tunnel packet:
1.1. If packet type indicates it has inner L3 and L3E is zero, then
mark the IP checksum good.
1.2. If packet type indicates it has inner L4 and L4E is zero, then
mark the L4 checksum good.
1.3. If packet type indicates it has outer L4 and OL4E is zero, then
mark the outer L4 checksum good.
2. If packet type indicates it's not tunnel packet:
2.1. If packet type indicates it has L3 and L3E is zero, then mark the
IP checksum good.
2.2. If packet type indicates it has L4 and L4E is zero, then mark the
L4 checksum good.
As described above, the good checksum calculation is time consuming,
it impacts the Rx performance.
By balancing performance and functionality, driver uses the following
scheme to set good checksum flag when L3L4P is 1:
1. If L3E is zero, then mark the IP checksum good.
2. If L4E is zero, then mark the L4 checksum good.

ethdev: add packet integrity check flow rules
Currently, DPDK application can offload the checksum check,
and report it in the mbuf.
However, as more and more applications are offloading some or all
logic and action to the HW, there is a need to check the packet
integrity so the right decision can be taken.
The application logic can be positive meaning if the packet is
valid jump / do actions, or negative if packet is not valid
jump to SW / do actions (like drop) and add default flow
(match all in low priority) that will direct the miss packet
to the miss path.
Since currently rte_flow works in positive way the assumption is
that the positive way will be the common way in this case also.
When thinking what is the best API to implement such feature,
we need to consider the following (in no specific order):
1. API breakage.
2. Simplicity.
3. Performance.
4. HW capabilities.
5. rte_flow limitation.
6. Flexibility.
First option: Add integrity flags to each of the items.
For example add checksum_ok to IPv4 item.
Pros:
1. No new rte_flow item.
2. Simple in the way that on each item the app can see
what checks are available.
Cons:
1. API breakage.
2. Increase number of flows, since app can't add global rule and must
have dedicated flow for each of the flow combinations, for example
matching on ICMP traffic or UDP/TCP traffic with IPv4 / IPv6 will
result in 5 flows.
Second option: dedicated item
Pros:
1. No API breakage, and there will be no for some time due to having
extra space. (by using bits)
2. Just one flow to support the ICMP or UDP/TCP traffic with IPv4 /
IPv6.
3. Simplicity application can just look at one place to see all possible
checks.
4. Allow future support for more tests.
Cons:
1. New item, that holds number of fields from different items.
For starter the following bits are suggested:
1. packet_ok - means that all HW checks depending on packet layer have
passed. This may mean that in some HW such flow should be split to
number of flows or fail.
2. l2_ok - all check for layer 2 have passed.
3. l3_ok - all check for layer 3 have passed. If packet doesn't have
L3 layer this check should fail.
4. l4_ok - all check for layer 4 have passed. If packet doesn't
have L4 layer this check should fail.
5. l2_crc_ok - the layer 2 CRC is O.K.
6. ipv4_csum_ok - IPv4 checksum is O.K. It is possible that the
IPv4 checksum will be O.K. but the l3_ok will be 0. It is not
possible that checksum will be 0 and the l3_ok will be 1.
7. l4_csum_ok - layer 4 checksum is O.K.
8. l3_len_OK - check that the reported layer 3 length is smaller than the
frame length.
Example of usage:
1. Check packets from all possible layers for integrity.
flow create integrity spec packet_ok = 1 mask packet_ok = 1 .....
Right now, rte_flow_shared_action_* APIs are used for some shared
actions, like RSS, count. The shared action should be created before
using it inside a flow. These shared actions sometimes are not
really shared but just some indirect actions decoupled from a flow.
The new functions rte_flow_action_handle_* are added to replace
the current shared functions rte_flow_shared_action_*.
There are two types of flow actions:
1. the direct (normal) actions that could be created and stored
within a flow rule. Such action is tied to its flow rule and
cannot be reused.
2. the indirect action, in the past, named shared_action. It is
created from a direct actioni, like count or rss, and then used
in the flow rules with an object handle. The PMD will take care
of the retrieve from indirect action to the direct action
when it is referenced.
The indirect action is accessed (update / query) w/o any flow rule,
just via the action object handle. For example, when querying or
resetting a counter, it could be done out of any flow using this
counter, but only the handle of the counter action object is
required.
The indirect action object could be shared by different flows or
used by a single flow, depending on the direct action type and
the real-life requirements.
The handle of an indirect action object is opaque and defined in
each driver and possibly different per direct action type.
The old name "shared" is improper in a sense and should be replaced.
Since the APIs are changed from "rte_flow_shared_action*" to the new
"rte_flow_action_handle*", the testpmd application code and command
line interfaces also need to be updated to do the adaption.
The testpmd application user guide is also updated. All the "shared
action" related parts are replaced with "indirect action" to have a
correct explanation.
The parameter of "update" interface is also changed. A general
pointer will replace the rte_flow_action struct pointer due to the
facts:
1. Some action may not support fields updating. In the example of a
counter, the only "update" supported should be the reset. So
passing a rte_flow_action struct pointer is meaningless and
there is even no such corresponding action struct. What's more,
if more than one operations should be supported, for some other
action, such pointer parameter may not meet the need.
2. Some action may need conditional or partial update, the current
parameter will not provide the ability to indicate which part(s)
to update.
For different types of indirect action objects, the pointer could
either be the same of rte_flow_action* struct - in order not to
break the current driver implementation, or some wrapper
structures with bits as masks to indicate which part to be
updated, depending on real needs of the corresponding direct
action. For different direct actions, the structures of indirect
action objects updating will be different.
All the underlayer PMD callbacks will be moved to these new APIs.
The RTE_FLOW_ACTION_TYPE_SHARED is kept for now in order not to
break the ABI. All the implementations are changed by using
RTE_FLOW_ACTION_TYPE_INDIRECT.
Since the APIs are changed from "rte_flow_shared_action*" to the new
"rte_flow_action_handle*" and the "update" interface's 3rd input
parameter is changed to generic pointer, the mlx5 PMD that uses these
APIs needs to do the adaption to the new APIs as well.

kni: fix kernel deadlock with bifurcated device
KNI runs userspace callback with rtnl lock held, this is not working
fine with some devices that needs to interact with kernel interface in
the callback, like Mellanox devices.
The solution is releasing the rtnl lock before calling the userspace
callback. But it requires two consideration:
1. The rtnl lock needs to released before 'kni->sync_lock', otherwise it
causes deadlock with multiple KNI devices, please check below the A.
for the details of the deadlock condition.
2. When rtnl lock is released for interface down event, it cause a
regression and deadlock, so can't release the rtnl lock for interface
down event, please check below B. for the details.
As a solution, interface down event is handled asynchronously and for
all other events rtnl lock is released before processing the callback.
A. KNI sync lock is being locked while rtnl is held.
If two threads are calling kni_net_process_request() ,
then the first one will take the sync lock, release rtnl lock then sleep.
The second thread will try to lock sync lock while holding rtnl.
The first thread will wake, and try to lock rtnl, resulting in a
deadlock. The remedy is to release rtnl before locking the KNI sync
lock.
Since in between nothing is accessing Linux network-wise, no rtnl
locking is needed.
B. There is a race condition in __dev_close_many() processing the
close_list while the application terminates.
It looks like if two KNI interfaces are terminating,
and one releases the rtnl lock, the other takes it,
updating the close_list in an unstable state,
causing the close_list to become a circular linked list,
hence list_for_each_entry() will endlessly loop inside
__dev_close_many() .
To summarize:
request != interface down : unlock rtnl, send request to user-space,
wait for response, send the response error code to caller in user-space.
request == interface down: send request to user-space, return immediately
with error code of 0 (success) to user-space.

pipeline: auto-detect endianness of action arguments
Each table entry is made up of match fields and action data, with the
latter made up of the action ID and the action arguments. The approach
of having the user specify explicitly the endianness of the action
arguments is difficult to be picked up by P4 compilers, as the P4
compiler is generally unaware about this aspect.
This commit introduces the auto-detection of the endianness of the
action arguments by examining the endianness of the their destination:
network byte order (NBO) when they get copied to headers and host byte
order (HBO) when they get copied to packet meta-data or mailboxes.
The endianness specification of each action argument as part of the
rule specification, e.g. H(...) and N(...) is removed from the rule
file and auto-detected based on their destination. The DMA instruction
scope is made internal, so mov instructions need to be used. The
pattern of transferring complete headers from table entry action args
to headers is detected, and the associated set of mov instructions
plus header validate is internally detected and replaced with the
internal-only DMA instruction to preserve performance.
This patch implements the Forwarding Information Base (FIB) library
in l3fwd using the function calls and infrastructure introduced in

The purpose of this commit is to add the necessary function calls
and supporting infrastructure to allow the Forwarding Information Base
(FIB) library to be integrated into the l3fwd sample app.
Instead of adding an individual flag for FIB, a new flag '--lookup' has
been added that allows the user to select their desired lookup method.
The flags '-E' and '-L' have been retained for backwards compatibility.

Any IP within the 2001:200::/48 subnet will match all the routes given
instead of 1 individual route and the application cannot
differentiate between them.
The change in this patch allows the ports to be individually matched using
smaller /64 ranges for each port. These smaller subnet ranges are still
within the 2001:200::/48 subnet range set aside for benchmarking
in RFC5180.
l3fwd will now use 2001:200:0:{0-7}::/64 where 0-7 is the port ID for IPv6.

The SWX pipeline instructions work with operands of different types:
header fields (h.header.field), packet meta-data (m.field), extern
object mailbox field (e.obj.field), extern function (f.field), action
data read from table entries (t.field), or immediate values; hence the
HMEFTI acronym. The H operands are stored in network byte order (NBO),
while the MEFT operands are stored in host byte order (HBO), hence the
need to operate endianness conversions.
Some of the endianness conversion macros were not working correctly
for some cases such as operands of different sizes, and they are fixed
now. Affected instructions: mov, and, or, xor, jmpeq, jmpneq.
Adjusting the error code for the internal function instruction_config
to match the rest of the code which is returning a negative value on
error. Cosmetic change.
Add support for table statistics for the SWX pipeline. For each table,
we maintain a counter for lookup hit packets, one for lookup miss
packets and one packet counter for each table action.
Enabled the TX instruction to accept an immediate value for the output
port argument. The drop instruction is simply an alias to the TX
instruction for the last output port of the pipeline.
The match fields for a given table have to be part of the same header
or the metadata structure. This commit removes the requirement that
the list of match fields must observe the order of fields within their
structure. For example, the h.ipv4.dst_addr field can now be listed
before the h.ipv4.src_addr field in a table match field list, even
though within the IPv4 header the dst_addr field is present after the
src_addr field.
Currently, the table entry action data is required to be NULL when the
action data size is zero. We now require that action data is ignored
when the action data size is zero. This is to allow for a table entry
instance to be allocated once with max action data size for the table
and reused repeatedly for actions of different sizes, including zero.

vfio: fix duplicated user mem map
Currently, new user mem maps are checked if they are adjacent to
an existing mem map and if so, the mem map entries are merged.
It didn't check for duplicate mem maps, so if the API is called
with the same mem map multiple times, they will occupy multiple
mem map entries. This will reduce the amount of entries available
for unique mem maps.
So check for duplicate mem maps and merge them into one mem map
entry if any found.

eventdev: fix case to initiate crypto adapter service
Initiate software crypto adapter service, only if hardware capabilities
are not reported. In OP_FORWARD mode, software service is not required
to enqueue events if OP_FORWARD capability is supported by the PMD.
In case an event from a previous stage is required to be forwarded
to a crypto adapter and PMD supports internal event port in crypto
adapter, exposed via capability
RTE_EVENT_CRYPTO_ADAPTER_CAP_INTERNAL_PORT_OP_FWD, we do not have
a way to check in the API rte_event_enqueue_burst(), whether it is
for crypto adapter or for eth tx adapter.
Hence we need a new API similar to rte_event_eth_tx_adapter_enqueue(),
which can send to a crypto adapter.
Note that RTE_EVENT_TYPE_* cannot be used to make that decision,
as it is meant for event source and not event destination.
And event port designated for crypto adapter is designed to be used
for OP_NEW mode.
Hence, in order to support an event PMD which has an internal event port
in crypto adapter (RTE_EVENT_CRYPTO_ADAPTER_OP_FORWARD mode), exposed
via capability RTE_EVENT_CRYPTO_ADAPTER_CAP_INTERNAL_PORT_OP_FWD,
application should use rte_event_crypto_adapter_enqueue() API to enqueue
events.
When internal port is not available(RTE_EVENT_CRYPTO_ADAPTER_OP_NEW mode),
application can use API rte_event_enqueue_burst() as it was doing earlier,
i.e. retrieve event port used by crypto adapter and bind its event queues
to that port and enqueue events using the API rte_event_enqueue_burst().

net/i40e: fix lack of MAC type when set MAC address
Currently, there is no way for a VF driver to specify that it wants to
change its device/primary unicast MAC address. This makes it
difficult/impossible for the PF driver to track the VF's device/primary
unicast MAC address, which is used for VM/VF reboot and displaying on
the host. Fix this by using 2 bits of a pad byte in the
virtchnl_ether_addr structure so the VF can specify what type of MAC
it's adding/deleting.
Below are the values that should be used by all VF drivers going
forward.
VIRTCHNL_ETHER_ADDR_LEGACY(0):
- The type should only ever be 0 for legacy AVF drivers (i.e.
drivers that don't support the new type bits). The PF drivers
will track VF's device/primary unicast MAC using with best
effort.
VIRTCHNL_ETHER_ADDR_PRIMARY(1):
- This type should only be used when the VF is changing their
device/primary unicast MAC. It should be used for both delete
and add cases related to the device/primary unicast MAC.
VIRTCHNL_ETHER_ADDR_EXTRA(2):
- This type should be used when the VF is adding and/or deleting
MAC addresses that are not the device/primary unicast MAC. For
example, extra unicast addresses and multicast addresses
assuming the PF supports "extra" addresses at all.
If a PF is parsing the type field of the virtchnl_ether_addr, then it
should use the VIRTCHNL_ETHER_ADDR_TYPE_MASK to mask the first two bits
of the type field since 0, 1, and 2 are the only valid values.
For i40evf PMD, when set default MAC address, use type
VIRTCHNL_ETHER_ADDR_PRIMARY as this case is changing device/primary
unicast MAC. For other cases, such as adding or deleting extra unicast
addresses and multicast addresses, use type VIRTCHNL_ETHER_ADDR_EXTRA.

Support rte flow priority attribute for DCF switch filter.
When a packet is matched by two rules, the behavior of it
is not defined. This patch supports flow priority to create
different recipes for this situation. Only priority 0 and 1
are supported and higher value denotes higher priority.
for example:
1. flow create 0 priority 0 ingress pattern eth / vlan tci is 2 / vlan
tci is 2 / end actions vf id 2 / end
2. flow create 0 priority 1 ingress pattern eth / vlan / vlan / ipv4 dst
is 192.168.0.1 / end actions vf id 1 / end
These two rules can be created at the same time in DCF switch
filter and priority of rule 2 is higher. Packet hits rule 2
when two conditions of rules are satisfied.
