[v7,00/21] add support for cpfl PMD in DPDK

  The patchset introduced the cpfl (Control Plane Function Library) PMD
for Intel® IPU E2100’s Configure Physical Function (Device ID: 0x1453)

The cpfl PMD inherits all the features from idpf PMD which will follow
an ongoing standard data plan function spec
https://www.oasis-open.org/committees/tc_home.php?wg_abbrev=idpf
Besides, it will also support more device specific hardware offloading
features from DPDK’s control path (e.g.: hairpin, rte_flow …). which is
different from idpf PMD, and that's why we need a new cpfl PMD.

This patchset mainly focuses on idpf PMD’s equivalent features.
To avoid duplicated code, the patchset depends on below patchsets which
move the common part from net/idpf into common/idpf as a shared library.

v2 changes:
 - rebase to the new baseline.
 - Fix rss lut config issue.
v3 changes:
 - rebase to the new baseline.
v4 changes:
 - Resend v3. No code changed.
v5 changes:
 - rebase to the new baseline.
 - optimize some code
 - give "not supported" tips when user want to config rss hash type
 - if stats reset fails at initialization time, don't rollback, just
   print ERROR info
v6 changes:
 - for small fixed size structure, change rte_memcpy to memcpy()
 - fix compilation for AVX512DQ
 - update cpfl maintainers
v7 changes:
 - add dependency in cover-letter

This patchset is based on the idpf PMD code:
