Merge branch 'expand-txtimestamp-selftest'
Willem de Bruijn says:
====================
expand txtimestamp selftest
Convert the existing txtimestamp test to run as part of kselftest
and return a pass/fail.
Also expand the variations of timestamping tested, including packet
sockets, ipv6 raw and dgram and passing options using cmsg.
These are enough changes to split across a few patches, even if all
changes are only this one test.
