From 4fab9071950c2021d846e18351e0f46a1cffd67b Mon Sep 17 00:00:00 2001 From: Neal Cardwell Date: Thu, 14 Aug 2014 12:40:05 -0400 Subject: tcp: fix tcp_release_cb() to dispatch via address family for mtu_reduced() Make sure we use the correct address-family-specific function for handling MTU reductions from within tcp_release_cb(). Previously AF_INET6 sockets were incorrectly always using the IPv6 code path when sometimes they were handling IPv4 traffic and thus had an IPv4 dst.
