From 0cc217e16cb8ca8ef2544363571fce94259900e0 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Wed, 26 Sep 2007 22:10:06 -0700 Subject: [IPV4]: When possible test for IFF_LOOPBACK and not dev == loopback_dev Now that multiple loopback devices are becoming possible it makes the code a little cleaner and more maintainable to test if a deivice is th a loopback device by testing dev->flags & IFF_LOOPBACK instead of dev == loopback_dev.
