From 8dc394af2e6159d3799b1219625db47c42a1964f Mon Sep 17 00:00:00 2001 From: Sucheta Chakraborty Date: Fri, 19 Jul 2013 16:56:29 -0400 Subject: [PATCH] qlcnic: Fix multicast packet handling for PF and VF. o Multicast MAC was not getting programmed due to which multicast packets were being dropped by FW. This patch fixes commit 168e4fb54c11865668ad50eff81b5f2729e0e0f4 ("qlcnic: Secondary unicast MAC address support.") which introduced bug in handling multicast packets.
