ice: Add support for PFCP hardware offload in switchdev
Add support for creating PFCP filters in switchdev mode. Add support for parsing PFCP-specific tc options: S flag and SEID. To create a PFCP filter, a special netdev must be created and passed to tc command: ip link add pfcp0 type pfcp tc filter add dev eth0 ingress prio 1 flower pfcp_opts \ 1:123/ff:fffffffffffffff0 skip_hw action mirred egress redirect \ dev pfcp0 Changes in iproute2 [1] are required to be able to use pfcp_opts in tc. ICE COMMS package is required to create a filter as it contains PFCP profiles.
