Subject[PATCH net-next 06/12] net: hns3: move some set_bit statement into hclge_prepare_mac_addr
Date
From: Weihang Li <liweihang@hisilicon.com>

This patch does not change the code logic. There are some same
set_bit statements called by add/rm_uc/mc_addr_common, and move
this statements into hclge_prepare_mac_addr to reduce duplicate
code.
