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. * 1-3: add new bitmap_{read,write}(), which is used later in the IP tunnel flags code (from Alexander's ARM64 MTE series[2]); * 4-14: some bitmap code preparations also used later in IP tunnels; * 15-17: convert IP tunnel flags from __be16 to a bitmap; * 18-21: add PFCP module and support for it in ice.
