When an application requests the use of a PCI device, it can currently
interchangeably use either the longform DomBDF format (0000:00:00.0) or
the shorter BDF format (00:00.0).
When a device is inserted via the hotplug API, it must first be scanned
and then will be identified by its name using `find_device`. The name of
the device must match the name given by the user to be found and then
probed.
A new function sets the expected name for a scanned PCI device. It was
previously generated from parsing the PCI address. This canonical name
is superseded when an rte_devargs exists describing the device. In such
case, the device takes the given name found within the rte_devargs.
As the rte_devargs is linked to the rte_pci_device during scanning, it
can be avoided during the probe. Additionally, this fixes the issue of
the rte_devargs lookup not being done within rte_pci_probe_one.

eal: fix hotplug add / remove
The hotplug API requires a few properties that were not previously
explicitly enforced:
- Idempotency, two consecutive scans should result in the same state.
- Upon returning, internal devices are now allocated and available
through the new `find_device` operator, meaning that they should be
identifiable.
The current rte_eal_hotplug_add implementation identifies devices by
their names, as it is readily available and easy to define.
The device name must be passed to the internal rte_device handle in
order to be available during scan, when it is then assigned to the
device. The current way of passing down this information from the device
declaration is through the global rte_devargs list.
Furthermore, the rte_device cannot take a bus-specific generated name,
as it is then not identifiable by the `find_device` operator. The device
must take the user-defined name. Ideally, an rte_device name should not
change during its existence.
This commit generates a new rte_devargs associated with the plugged
device and inserts it in the global rte_devargs list. It consequently
releases it upon device removal.

devargs: introduce insert function
Some buses will operate either in whitelist or blacklist mode.
This mode is currently passed down by the rte_eal_devargs_add function
with the devtype argument.
When inserting devices using the hotplug API, the implicit assumption is
that this device is being whitelisted, meaning that it is explicitly
requested by the application to be used. This can conflict with the
initial bus configuration.
While the rte_eal_devargs_add API is being deprecated soon, it cannot
be modified at the moment to accommodate this situation.
As such, this new experimental API offers a bare interface for inserting
rte_devargs without directly manipulating the global rte_devargs list.
This new function expects a fully-formed rte_devargs, previously parsed
and allocated.
It does not check whether the new rte_devargs is compatible with current
bus configuration, but will replace any eventual existing one for the same
device, allowing the hotplug operation to proceed. i.e. a previously
blacklisted device can be redefined as being whitelisted.

- Capability query API per port, per level and per node
- Scheduling algorithms: Strict Priority (SP), Weighed Fair Queuing (WFQ)
- Traffic shaping: single/dual rate, private (per node) and shared (by

ethdev: add traffic management ops get API
The rte_flow feature breaks the monolithic approach for ethdev by
introducing the new rte_flow API to ethdev using a plugin-like approach.
Basically, the rte_flow API is still logically part of ethdev:
- It extends the ethdev functionality: rte_flow is a new feature/
capability of ethdev;
- all its functions work on an Ethernet device: the first parameter of the
rte_flow functions is Ethernet device port ID.
Also, the rte_flow API is a sort of capability plugin for ethdev:
- the rte_flow API functions have their own name space: they are called
rte_flow_operationXYZ() as opposed to rte_eth_dev_flow_operationXYZ());
- the rte_flow API functions are placed in separate files in the same
librte_ether folder as opposed to rte_ethdev.[hc].
The way it works is by using the existing ethdev API function
rte_eth_dev_filter_ctrl() to query the current Ethernet device port ID for
the support of the rte_flow capability and return the pointer to the
rte_flow operations when supported and NULL otherwise:
struct rte_flow_ops *eth_flow_ops;
int rte = rte_eth_dev_filter_ctrl(eth_port_id,
RTE_ETH_FILTER_GENERIC, RTE_ETH_FILTER_GET, ð_flow_ops);
This patch reuses the same approach for ethdev Traffic Management API.

lib/gro: support TCP/IPv4
In this patch, we introduce five APIs to support TCP/IPv4 GRO.
- gro_tcp4_reassemble: reassemble an inputted TCP/IPv4 packet.
- gro_tcp4_tbl_create: create a TCP/IPv4 reassembly table, which is used
to merge packets.
- gro_tcp4_tbl_destroy: free memory space of a TCP/IPv4 reassembly table.
- gro_tcp4_tbl_pkt_count: return the number of packets in a TCP/IPv4
reassembly table.
- gro_tcp4_tbl_timeout_flush: flush timeout packets from a TCP/IPv4
reassembly table.
TCP/IPv4 GRO API assumes all inputted packets are with correct IPv4
and TCP checksums. And TCP/IPv4 GRO API doesn't update IPv4 and TCP
checksums for merged packets. If inputted packets are IP fragmented,
TCP/IPv4 GRO API assumes they are complete packets (i.e. with L4
headers).
In TCP/IPv4 GRO, we use a table structure, called TCP/IPv4 reassembly
table, to reassemble packets. A TCP/IPv4 reassembly table includes a key
array and a item array, where the key array keeps the criteria to merge
packets and the item array keeps packet information.
One key in the key array points to an item group, which consists of
packets which have the same criteria value. If two packets are able to
merge, they must be in the same item group. Each key in the key array
includes two parts:
- criteria: the criteria of merging packets. If two packets can be
merged, they must have the same criteria value.
- start_index: the index of the first incoming packet of the item group.
Each element in the item array keeps the information of one packet. It
mainly includes three parts:
- firstseg: the address of the first segment of the packet
- lastseg: the address of the last segment of the packet
- next_pkt_index: the index of the next packet in the same item group.
All packets in the same item group are chained by next_pkt_index.
With next_pkt_index, we can locate all packets in the same item
group one by one.
To process an incoming packet needs three steps:
a. check if the packet should be processed. Packets with one of the
following properties won't be processed:
- FIN, SYN, RST, URG, PSH, ECE or CWR bit is set;
- packet payload length is 0.
b. traverse the key array to find a key which has the same criteria
value with the incoming packet. If find, goto step c. Otherwise,
insert a new key and insert the packet into the item array.
c. locate the first packet in the item group via the start_index in the
key. Then traverse all packets in the item group via next_pkt_index.
If find one packet which can merge with the incoming one, merge them
together. If can't find, insert the packet into this item group.

lib/gro: add Generic Receive Offload API framework
Generic Receive Offload (GRO) is a widely used SW-based offloading
technique to reduce per-packet processing overhead. It gains
performance by reassembling small packets into large ones. This
patchset is to support GRO in DPDK. To support GRO, this patch
implements a GRO API framework.
To enable more flexibility to applications, DPDK GRO is implemented as
a user library. Applications explicitly use the GRO library to merge
small packets into large ones. DPDK GRO provides two reassembly modes.
One is called lightweight mode, the other is called heavyweight mode.
If applications want to merge packets in a simple way and the number
of packets is relatively small, they can use the lightweight mode.
If applications need more fine-grained controls, they can choose the
heavyweight mode.
rte_gro_reassemble_burst is the main reassembly API which is used in
lightweight mode and processes N packets at a time. For applications,
performing GRO in lightweight mode is simple. They just need to invoke
rte_gro_reassemble_burst. Applications can get GROed packets as soon as
rte_gro_reassemble_burst returns.
rte_gro_reassemble is the main reassembly API which is used in
heavyweight mode and tries to merge N inputted packets with the packets
in GRO reassembly tables. For applications, performing GRO in heavyweight
mode is relatively complicated. Before performing GRO, applications need
to create a GRO context object, which keeps reassembly tables of
desired GRO types, by rte_gro_ctx_create. Then applications can use
rte_gro_reassemble to merge packets. The GROed packets are in the
reassembly tables of the GRO context object. If applications want to get
them, applications need to manually flush them by flush API.
