[ 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.
