Add support for dissecting PPPoE and PPP-specific fields in flow dissector: PPPoE session id and PPP protocol type. Add support for those fields in tc-flower and support offloading PPPoE. Finally, add support for hardware offload of PPPoE packets in switchdev mode in ice driver. Example filter: tc filter add dev $PF1 ingress protocol ppp_ses prio 1 flower pppoe_sid \ 1234 ppp_proto ip skip_sw action mirred egress redirect dev $VF1_PR Changes in iproute2 are required to use the new fields (will be submitted soon). ICE COMMS DDP package is required to create a filter in ice. Note: currently matching on vlan + PPPoE fields is not supported. Patch [0] will add this feature.
