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.
