Subject: [PATCH net 11/19] net: hns: Remove the redundant adding and deleting mac function
From: Kejian Yan <yankejian@...wei.com>
The functions (hns_dsaf_set_mac_mc_entry() and hns_mac_del_mac()) are
not called by any functions. They are dead code in hns. And the same
features are implemented by the patch (the id is 66355f5).
