If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 070674fb523fb3c395917b95765137adfaf9e175 Author: Ivan Mikhaylov <fr0st61te@xxxxxxxxx> Date: Wed Jun 7 18:17:42 2023 +0300 net/ncsi: change from ndo_set_mac_address to dev_set_mac_address [ Upstream commit 790071347a0a1a89e618eedcd51c687ea783aeb3 ] Change ndo_set_mac_address to dev_set_mac_address because dev_set_mac_address provides a way to notify network layer about MAC change. In other case, services may not aware about MAC change and keep using old one which set from network adapter driver. As example, DHCP client from systemd do not update MAC address without notification from net subsystem which leads to the problem with acquiring the right address from DHCP server.
