From 0e91796eb46e29edc791131c832a2232bcaed9dd Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Tue, 20 May 2008 14:36:14 -0700 Subject: [PATCH] net: Fix call to ->change_rx_flags(dev, IFF_MULTICAST) in dev_change_flags() Am I just being particularly dim today, or can the call to dev->change_rx_flags(dev, IFF_MULTICAST) in dev_change_flags() never happen? We've just set dev->flags = flags & IFF_MULTICAST, effectively. So the condition '(dev->flags ^ flags) & IFF_MULTICAST' is _never_ going to be true.
