Find an IP address on this machine to use as a source IP, and
make up a destination IP address based on the source IP.  No
actual messages will be sent, just a couple of IPsec rules are
created and deleted.

a "Terminated" message when the subprogram is killed.

When net test is skipped because of unmet dependencies and/or unsupported
configuration, it returns 0 which is treated as a pass by the Kselftest
framework. This leads to false positive result even when the test could
not be run.

Change it to return kselftest skip code when a test gets skipped to
clearly report that the test could not be run.

Kselftest framework SKIP code is 4 and the framework prints appropriate
messages to indicate that the test is skipped.

Change psock_tpacket to use ksft_exit_skip() when a non-root user runs
the test and add an explicit check for root and a clear message, instead
of failing the test when /sys/power/state file open fails.

add a simple script to exercise some rtnetlink call paths, so KASAN,
lockdep etc. can yell at developer before patches are sent upstream.

This can be extended to also cover bond, team, vrf and the like.
