ice: add PFCP filter support
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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
