Subject: tunneling: Fix uninitialized variable warning in check_mtu.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ee3cdc0028ad4c5a665075fe9ce35c79b5cbbeb1;p=openvswitch

tunneling: Fix uninitialized variable warning in check_mtu.

The MTU is only needed if we are doing PMTUD but some compilers
complain that it could be used uninitialized.
