hosts, for example the same single NIC can be shared for multiple server
units in the rack. On each PCIe link NIC can provide multiple PFs and
VFs/SFs based on these ones. The full representor identifier consists of
three indices - controller index, PF index, and VF or SF index (if any).

SR-IOV and SubFunction are created on top of PF. PF index is introduced
because there might be multiple PFs in the bonding configuration and
only bonding device is probed.

In eth representor comparator callback, ethdev representor ID was
compared with devarg. Since controller index and PF index not compared,
callback returned representor from other PF or controller.

This patch adds new API to get representor ID from controller, pf and
vf/sf index. Representor comparer callback get representor ID then
compare with device representor ID.

0xffff. This register will revert back to the normal value after

net/af_xdp: prefer busy polling

This commit introduces support for preferred busy polling
to the AF_XDP PMD. This feature aims to improve single-core
performance for AF_XDP sockets under heavy load.

A new vdev arg is introduced called 'busy_budget' whose default
value is 64. busy_budget is the value supplied to the kernel
with the SO_BUSY_POLL_BUDGET socket option and represents the
busy-polling NAPI budget. To set the budget to a different value
eg. 256:

--vdev=net_af_xdp0,iface=eth0,busy_budget=256

Preferred busy polling is enabled by default provided a kernel with
version >= v5.11 is in use. To disable it, set the budget to zero.

The following settings are also strongly recommended to be used in
conjunction with this feature:

echo 2 | sudo tee /sys/class/net/eth0/napi_defer_hard_irqs
echo 200000 | sudo tee /sys/class/net/eth0/gro_flush_timeout

.. where eth0 is the interface being used by the PMD.

Prior to this commit, the maximum batch sizes for zero-copy and

the user could never rx/tx any more than 32 packets at a time and
without inspecting the code the user wouldn't be aware of this.

This commit removes these upper limits placed on the user and instead
sets an internal batch size equal to the default ring size (2048).
Batches larger than this are still processed, however they are split
into smaller batches similar to how it's done in other drivers. This is
necessary because some arrays used during rx/tx need to be sized at
compile-time.

Allowing a larger batch size allows for fewer batches and thus larger
bulk operations, fewer ring accesses and fewer syscalls which should
yield improved performance.

eal: fix querying DPDK version at runtime

For using a DPDK application, such as OVS, which is dynamically linked, the
DPDK version in use should always report the actual version, not the
version used at build time. This incorrect behaviour can be seen by
building OVS against one version of DPDK and running it against a later
one. Using "ovs-vsctl list Open_vSwitch" to query basic info, the
dpdk_version returned will be the build version not the currently running

necessary parts of the rte_version.h, to be actual functions in EAL, not
just inlines/macros. The only complication in doing so is that telemetry

net/mlx5: fix Rx segmented packets on mbuf starvation

The issue occurred if mbuf starvation happened
in the middle of segmented packet reception.
In such a situation, after release the segments of
packet being received, code did not advance the
consumer index to the next stride. This caused
the receiving of the wrong segmented packet data.

The possible error scenario:
- we assume segs_n is 4 and we are receiving 4
  segments of multi-segment packet.
- we fail to allocate mbuf while receiving the 3rd segment,
  and this frees the mbufs of the packet chain we have built.
  There are the 1st and 2nd segments in the chain.
- the 1st and the 2nd segments of this stride of Rx queue
  are filled up (in elts array) with the new allocated
  mbufs and their data are random (the 3rd and 4th
  segments still contain the valid data of the packet though).
- on the next iteration of stride processing we get
  the wrong two segments of the multi-segment packet.

Hence, we should skip these mbufs in the stride and
we should advance the consumer index on loop exit.
