Subject: ofp-parse: Fix GCC compiler warnings with -O3.
X-Git-Tag: v2.3~758
X-Git-Url: http://git.cascardo.eti.br/?a=commitdiff_plain;h=87f1e513e1388107014fb3df461f30d7f58c6dec;p=cascardo%2Fovs.git

ofp-parse: Fix GCC compiler warnings with -O3.

When compiling with -O3, GCC can no longer tell that the following
warnings are not valid.  At any rate, they're easy enough to silence.

ofp-parse.c:764:45: error: 'ttl' may be used uninitialized in this
function

ofp-parse.c:752:17: error: 'ecn' may be used uninitialized in this
function
