Subject: [PATCH] net: ipg: fix receivemode IPG_RM_RECEIVEMULTICAST{,HASH} in ipg_nic_set_multicast_list()
Date: Tue, 13 May 2008 22:32:48 +0200 [thread overview]
Message-ID: <4829FAF0.2040403@gmail.com> (raw)
The branches are dead code. even when dev->flag IFF_MULTICAST (defined 0x1000)
is set, dev->flags & IFF_MULTICAST & [boolean] always evaluates to 0.
