Subject: [PATCH net-next] tcp: Fix bug in tcp socket early demux
Date: Sat, 23 Jun 2012 20:38:10 -0700 [thread overview]
Message-ID: <1340509090-2819-1-git-send-email-subramanian.vijay@gmail.com> (raw)
The dest port for the call to __inet_lookup_established() in TCP early demux
code is passed with the wrong endian-ness. This causes the lookup to fail
leading to early demux not being used.
