Linux network drivers normally disallow changing the MAC address when the interface is up. This driver has been different in that it allows to change the MAC address *only* when it's up. This patch brings wilc1000 behavior more in line with other network drivers. We could have replaced wilc_set_mac_addr() with eth_mac_addr() but that would break existing documentation on how to change the MAC address. Likewise, return -EADDRNOTAVAIL (not -EINVAL) when the specified MAC address is invalid or unavailable.
