v2 updates:
- reabse on to latest DPIF v11
This patchset introduces miniflow extract Infrastructure changes
which allows user to choose different type of ISA based optimized
miniflow extract variants which can be user choosen or set based on
packets studies automatically by OVS using different commands.
The Infrastructure also provides a way to check the correctness of
different ISA optimized miniflow extract variants against the scalar
version.
This Patchset depends on the DPIF patchsets :

Kumar Amber (6):
dpif-netdev: Add command line and function pointer for miniflow
extract
dpif-netdev: Add auto validation function for miniflow extract
dpif-netdev: Add study function to select the best mfex function
dpif-netdev: add avx512 miniflow extract for traffic ip/udp
docs/dpdk/bridge: add miniflow extract section.
dpif-netdev: Add configure to enable autovalidator at build time.

Hi,
we (as Red Hat) did some tests with a "special" build created on top of
master (a019868a6268 at that time) with with the 2 series ("DPIF
Framework + Optimizations" and "MFEX Infrastructure + Optimizations")
cherry-picked.
The spec file was also modified in order to use add "-msse4.2 -mpopcnt"
to OVS CFLAGS.
RPM=openvswitch2.15-2.15.0-37.avx512.1.el8fdp (the "special" build with
the patches backported)
* Master --- 15.2 Mpps
* Plus "avx512_gather 3" Only --- 15.2 Mpps
* Plus "dpif-set dpif_avx512" Only --- 10.1 Mpps
* Plus "miniflow-parser-set study" --- Failed to converge
* Plus all three --- 13.5 Mpps
RPM=openvswitch2.15-2.15.0-15.el8fdp (w/o "-msse4.2 -mpopcnt")
* 15.2 Mpps
P2P benchmark
* ovs-dpdk/25 Gb i40e <-> trex/i40e
* single queue two pmd's --- two HT's out of a CPU core.
