Add support for creating PFCP filters in switchdev mode. Add pfcp module
that allows to create a PFCP-type netdev. The netdev then can be passed to
tc when creating a filter to indicate that PFCP filter should be created.
To add 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 \
1:12ab/ff:fffffffffffffff0 skip_hw action mirred egress redirect \
dev pfcp0
Changes in iproute2 [1] are required to use pfcp_opts in tc.
ICE COMMS package is required as it contains PFCP profiles.
Part of this patchset modifies IP_TUNNEL_*_OPTs, which were previously
stored in a __be16. All possible values have already been used, making it
impossible to add new ones.

This patchset should be applied on top of the "boys" tree [2], as it
depends on recent bitmap changes.
Is this for comment only (RFC)? This doesn't seem to apply to iwl-next
and if this based on, and has dependencies from, another tree, I can't
apply them here.
