The following patches will operate with more exit codes besides
ksft_skip. Add them here.
Additionally, move a duplicated skip exit code definition from
forwarding/tc_tunnel_key.sh. Keep a similar duplicate in
forwarding/devlink_lib.sh, because even though lib.sh will have
been sourced in all cases where devlink_lib is, the inclusion is not
visible in the file itself, and relying on it would be confusing.

The test installs filters that match on various IP fragments (e.g., no
fragment, first fragment) and expects a certain amount of packets to hit
each filter. This is problematic as the filters are not specific enough
and can match IP packets (e.g., IGMP) generated by the stack, resulting
in failures [1].
Fix by making the filters more specific and match on more fields in the
IP header: Source IP, destination IP and protocol.

Add a selftest that configures metadata tunnel encapsulation using the TC
"tunnel_key" action: it includes a test case for setting "nofrag" flag.
Example output:
# selftests: net/forwarding: tc_tunnel_key.sh
# TEST: tunnel_key nofrag (skip_hw) [ OK ]
# INFO: Could not test offloaded functionality
ok 1 selftests: net/forwarding: tc_tunnel_key.sh
