Subject: sctp: Guard IPV6 specific code properly.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5d0c90cf4d417ccafcd1af4ec32945c3f80e98e2;p=linux-beck.git

sctp: Guard IPV6 specific code properly.

Outside of net/sctp/ipv6.c, IPV6 specific code needs to
be ifdef guarded.

This fixes build failures with IPV6 disabled.
