From: stephen hemminger Date: Fri, 13 Dec 2013 20:35:56 +0000 (-0800) Subject: net: remove dead code for add/del multiple X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=477bb93320cec7ae74d5ccfad4f2bfa0b28fbe90;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git net: remove dead code for add/del multiple These function to manipulate multiple addresses are not used anywhere in current net-next tree. Some out of tree code maybe using these but too bad; they should submit their code upstream.. Also, make __hw_addr_flush local since only used by dev_addr_lists.c Signed-off-by: Stephen Hemminger Signed-off-by: David S.
