Subject: [iproute PATCH v2 3/7] iproute: Fix for missing 'Oifs:' display

Covscan complained about dead code but after reading it, I assume the
author's intention was to prefix the interface list with 'Oifs: '.
Initializing first to 1 and setting it to 0 after above prefix was
printed should fix it.
