Add a specific path for RX AVX512 (flexible descriptor).
In this path, support the HW offload features, like, checksum, VLAN
stripping, RSS hash.
This path is chosen automatically according to the configuration.

'inline' is used, then the duplicate code is generated by the
compiler.

There is already a iavf bullet in the section, "Updated Intel iavf driver", can
you please add updates under it?

Will move this to there. Thanks.
