From 735d383117e113403442d971b23e7cfa2f876c7c Mon Sep 17 00:00:00 2001
From: Florian Westphal <fw@strlen.de>

Subject: tcp: change TCP_ECN prefixes to lower case
Suggested by Stephen. Also drop inline keyword and let compiler decide.
gcc 4.7.3 decides to no longer inline tcp_ecn_check_ce, so split it up.
The actual evaluation is not inlined anymore while the ECN_OK test is.
