[ath9k-devel] Does ath9k distinguish AR9280 and AR9281?

[Luca Niccoli]

Hi,

I have an atheros card that came with the laptop, so I don't know for
sure the chipset.
dmesg says:
phy0: Atheros AR9280 MAC/BB Rev:2 AR5133 RF Rev:d0:
mem=0xffffc90004180000, irq=17

but iw phy reports it as single band.
As I understand it, AR9280 should be dual band, and shouldn't have a
separate phy, so I don't even get what that AR5133 is about...
Is it supposed to be so, that the single and dual band are
distingushed only by which frequencies one can choose?
And why does the driver report about the transreceiver (which should
be dual-band anyway)?
Thanks,

Luca
P.S.
Please CC me

Likely we don't distinguish on the name output AR9280 vs AR9281,
should be a trivial fix, just as renaming AR9220 to PCI AR9280,
but it hasn't been prioritized.

Ignore that, on recent kernels that second output is removed.
The radios on integrated on the single chip post AR9280. You can
read the top of phy.c for more info.

It caused me a bit of confusion while trying to understand why I
couldn't connect to a 5Ghz network, but I probably should have trusted
iw in the first place.

Oh, I actually read the patch that introduced that, but failed to
notice that it wasn't merged in 2.6.32, so I didn't understand what
was going on..


Thank you!
