From 687a25f1cdfc6ee1f2f60f299dbd294908eb0d59 Mon Sep 17 00:00:00 2001 From: Allan Stephens Date: Sun, 25 Jun 2006 23:43:21 -0700 Subject: [TIPC]: Validate entire interface name when locating bearer to enable. This fix prevents a bearer from being enabled using the wrong interface. For example, specifying "eth:eth14" might enable "eth:eth1" by mistake.
