[dpdk-dev] [PATCH 24/27] net/ice/base: add eCPRI over MAC type 0 flow support

Tue Dec 15 07:05:16 CET 2020
This patch adds extracting field for flow type eCPRI over mac message
type 0 and field PC_ID which is used for FDIR/RSS packet steering.
This patch also removes redundant hdr bitmask ops for PPPOE hdr.
