tun_metadata can work only if in_port and out_port are GENEVE tunnel
port, it is designed specially for GENEVE, Eth+NSH can work without
any tunnel port involved, context headers for NSH are not tunnel
metadata, they aren't tunnel-specific, you can't treat them as same
thing. In addtition, tun_metadata also can be matched and set, they have
the same issue as you concern.
