From: Luca Coelho <luciano.coelho@xxxxxxxxx>
At least in some older kernel versions (e.g. 3.10), the tcp.h header
file is not implicitly included from other headers if CONFIG_IPV6 is
not set, so we need to include it in backport-4.4.c. Also, there is
an IPv6 structure that is used, so we should ifdef it away when IPv6
is not enabled.
