From 5fcaed0124cde73124227542bfce4ed57fccbb50 Mon Sep 17 00:00:00 2001 From: Benjamin Li Date: Mon, 14 Jul 2008 22:39:52 -0700 Subject: [PATCH] bnx2: Support secondary MAC addresses. Add support for configuring secondary unicast addresses. There are 4 additional perfect match filters which can be used for secondary unicast address support. * Modified bnx2_set_mac_addr() to be more generic in handling the setting of the perfect match filters * Changed bnx2_set_rx_mode() to handle the unicast dev_addr_list Signed-off-by: Benjamin Li Signed-off-by: Michael Chan Signed-off-by: David S.
