[ath9k-devel] Is there a way to tell if an antenna is connected?

[Ben Greear]

Any register to query or other way to tell if an antenna is
actually connected to the NIC?  I'd like to be able to warn
users if the connector pops off for whatever reason...

Thanks,
Ben

Not that I know of.

I'd look at the NF sample readings and if they're too far apart from
each other, I'd spit out a big warning.
