Atheros 9280 Issues

[Joe Holden]

Hi,

Having inspected the ath code and edited ah_regdomain.c so that it 
continues to attach, even if there is no regdomain specified, or its 
invalid, it successfully attached and I was able to set the regdomain and 
associate.

Throughput isn't particularly good, and also there are alot of hardware 
reset messages, but that doesn't seem to have any ill effects.

Thanks,
J
