    ath79: increase max tx ring buffer for ag71xx
    
    This allows the user to specify a larger tx ring buffer size via ethtool.
    Having symmetrical ring buffer sizes increases throughput on high bandwidth
    (1 gbps tested) network connections.
    
    The default value is not changed so the same behaviour is saved.
