[PATCH] net: ipg: fix receivemode IPG_RM_RECEIVEMULTICAST{,HASH}in ipg_nic_set_multicast_list()

From: Roel Kluin
Date: Tue May 13 2008 - 16:33:07 EST


The branches are dead code. even when dev->flag IFF_MULTICAST (defined 0x1000)
is set, dev->flags & IFF_MULTICAST & [boolean] always evaluates to 0.
