This makes the networking core depend upon CONFIG_INET.

You will have to untangle this somehow before your final submission.
Probably with an inline helper in the non-INET case that always
returns TCP_CA_UNSPEC.

good point. Perhaps net/ipv4/metrics.c is a better place for it given
that ipv4/ipv6 common code appears to be under net/ipv4. I need to play
with the config build permutations.
