Subject: net: thunderx: Use fwnode_get_mac_address()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d86afb89305de205b0d2f20c2160adf039e9508d;p=openwrt%2Fstaging%2Fblogic.git

net: thunderx: Use fwnode_get_mac_address()

Replace the custom implementation with fwnode_get_mac_address,
which works on both DT and ACPI platforms.

While here, replace memcpy() by ether_addr_copy().
