[PATCH 4.9 047/109] be2net: fix unicast list filling
From: Greg Kroah-Hartman
Date: Thu Dec 07 2017 - 09:02:14 EST
4.9-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 6052cd1af86f9833b6b0b60d5d4787c4a06d65ea ]
The adapter->pmac_id[0] item is used for primary MAC address but
this is not true for adapter->uc_list[0] as is assumed in
be_set_uc_list(). There are N UC addresses copied first from net_device
to adapter->uc_list[1..N] and then N UC addresses from
adapter->uc_list[0..N-1] are sent to HW. So the last UC address is never
stored into HW and address 00:00:00:00;00:00 (from uc_list[0]) is used
instead.
