From: Ivan Vecera Date: Fri, 6 Jan 2017 19:30:02 +0000 (+0100) Subject: be2net: fix accesses to unicast list X-Git-Tag: v5.15~12110^2~5 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1d0f110a2c6c4bca3dbcc4b0e27f1e3dc2d44a2c;p=platform%2Fkernel%2Flinux-starfive.git be2net: fix accesses to unicast list 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.
