Subject: ethernet: manually convert memcpy(dev_addr,..., sizeof(addr))
Patch-mainline: v5.16-rc1
Git-commit: c51e5062c18067ccdc85798c2051edfc37e2475d
References: jsc#PED-1565
A handful of drivers use sizeof(addr) for the size of
the address, after manually confirming the size is
indeed 6 convert them to eth_hw_addr_set().
