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.
