    ar71xx: limit Ethernet speed of UBNT Airmax M (XM) devices to 100Mbit/s
    
    Some Airmax devices can establish a Gigabit link even though the MAC only
    supports 10/100 MBit/s, leading to broken connectivity. Prevent this from
    happening by limiting the speed to 100MBit/s.
    
    Fixes: FS#296
