net/ncsi: change from ndo_set_mac_address to dev_set_mac_address
Browse files Browse the repository at this point in the history
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.

Fixes: cb10c7c ("net/ncsi: Add NCSI Broadcom OEM command")
