Oh, and the other thing to keep in mind - this is part of the Atheros
"partial offload" architecture which we shipped for a few customers.

One AR7010 variant (AR7011? I think?) had an MII+ethernet interface rather
than USB interface. So you'd talk to the device over the MII+ethernet
interface direct from another master CPU.

So the master AP would have a CPU and wifi chip, and the slave/offload
(AR7010 or derivative) would do offloaded frame transmission/reception.

So it's quite possible that there's some carrier / enterprise solution
somewhere that uses the AR7010 as an offload CPU for an AR5418 device. But
I don't think we'll see it for USB offload.

(Yes, I'd eventually like us to support the ethernet offload mode - even if
it's just as a reference we can use internally at work when demo'ing stuff.)
