4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Ivan Vecera <cera@xxxxxxx> [ Upstream commit 1d0f110a2c6c4bca3dbcc4b0e27f1e3dc2d44a2c ] Commit 988d44b "be2net: Avoid redundant addition of mac address in HW" introduced be_dev_mac_add & be_uc_mac_add helpers that incorrectly access adapter->uc_list as an array of bytes instead of an array of be_eth_addr. Consequently NIC is not filled with valid data so unicast filtering is broken.
