[PATCH 6.6.y 0/2] fix push_nsh() validation + silence selftest warnings

[Adrian Yip <adrian.ytw@gmail.com>]

Hi maintainers,

This is a v6.6 backport mainly for an upstream commit `5ace7ef87f05 net: 
openvswitch: fix middle attribute validation in push_nsh() action`.

I built the kernel then tested it with selftest. The selftest that ran
with a a bunch of SyntaxWarning.

Example:
  /ovs-dpctl.py:598: SyntaxWarning: invalid escape sequence '\d'
    actstr, ":", "(\d+)", int, False
  /ovs-dpctl.py:601: SyntaxWarning: invalid escape sequence '\d'
    actstr, "-", "(\d+)", int, False
  /ovs-dpctl.py:505: SyntaxWarning: invalid escape sequence '\d'
    elif parse_starts_block(actstr, "^(\d+)", False, True):

This error was then easily fixed with another minimal backport for the
file tools/testing/selftests/net/openvswitch/ovs-dpctl.py. Hence the
series.

Both patches was applied cleanly and was tested with selftest and passed
though the timeout had to be increased for drop_reason to pass.
