Subject: [PATCH 1/9] staging: ks7010: Replace manual array copy with ether_addr_copy().

Copying the dummy HW address into the struct net_device doesn't need
to be done byte by byte; use ether_addr_copy() instead.
Additionally, dev->dev_addr is not eight bytes long.
ether_setup() sets the dev->addr_len to ETH_ALEN (defined as 6)
in the net core code.
