kern/154007: [ath] Atheros ar9287 card does not get recognized.

[Adrian Chadd]

Hiya,

I'll take this over.

Making it recognised isn't going to be too difficult. Making it
stable, that's a whole other problem. I'm happy to commit the bare
minimum needed to make the AR9287 recognised but there's quite a bit
of further work needing to be done to the AR9280 support before I'm
comfortable working on AR9285/AR9287.

If you know of a place to acquire AR9285/AR9287 equipment then please
let me know so I can acquire some also.
