Did you mark the interface down?  When you do that it should power off 
the radio and the stop the mac's clock.

Device id 0x1014 is not pcie as far as I know and I've never seen an 
Atheros card that supports MSI so something doesn't make sense here 
(perhaps I'm just unaware of MSI support coming in).
