Subject: tcp: Fix bug in tcp socket early demux
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=7011d0851b80a1a229acfda37ce08aad903b12d1;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git

tcp: Fix bug in tcp socket early demux

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.
