* For WNR2200 ART flash area used for WLAN MAC is usually empty (0xff)
* so ath9k driver uses random MAC instead each time module is loaded.
* OpenWrt's original fix was to copy eth1 address to WLAN interface.
* New solution does not duplicate hardware addresses and is taken from
* WNR2000v3 code. It assigns permanent WLAN MAC equal to ethN's MAC
* plus 1, so network interfaces get sequential addresses.
* If ART wireless MAC address field has been filled by user, use it.
