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.

It's not an RFC.
The series contains generic code changes and must go directly through
net-next.

Should this be marked for 'net-next' rather than 'iwl-next' then?

Thanks,
Tony

The dependency on the bitmap tree was discussed with Jakub and
Yury and we agreed that the netdev guys will pull it before applying
this one.

Thanks,
Olek
