From 01789349ee52e4a3faf376f1485303d9723c4f1f Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Tue, 16 Aug 2011 06:29:00 +0000 Subject: net: introduce IFF_UNICAST_FLT private flag Use IFF_UNICAST_FTL to find out if driver handles unicast address filtering. In case it does not, promisc mode is entered. Patch also fixes following drivers: stmmac, niu: support uc filtering and yet it propagated ndo_set_multicast_list bna, benet, pxa168_eth, ks8851, ks8851_mll, ksz884x : has set ndo_set_rx_mode but do not support uc filtering Signed-off-by: Jiri Pirko Signed-off-by: David S.
