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