#1361702 — [PATCH net 03/10] net: hns: add uc match for debug ports

From: Kejian Yan <yankejian@huawei.com>

Debug ports receives lots of packets with dest mac addr does not match
local mac addr, because the filter is close, and it does not drop the
useless packets. This patch adds ON/OFF switch of filtering the packets
whose dest mac addr do not match the local addr in  mac table. And the
switch is ON in initialization.

This cast to void is unnecssary.

Casts from void pointers are unnecessary.

Likewise.

I think hns_mac_set_promisc don't need to return a value， so i will fix it in next submit.

Thanks
