From: Jitendra Kalsaria Date: Sat, 22 Jun 2013 08:12:01 +0000 (-0400) Subject: qlcnic: Secondary unicast MAC address support. X-Git-Tag: next-20130628~73^2~74 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=52e493d01cbf85871f0d1fdaeffdf376444e5d50;p=karo-tx-linux.git qlcnic: Secondary unicast MAC address support. Add support for configuring secondary unicast address which will use existing HW filters to store all the unicast MAC addresses and prevent device going into promiscuous mode.
