[PATCH] ath9k : Display MAC/BB and RF version at startup

[PATCH] ath9k : Display MAC/BB and RF version at startup

[Benoit PAPILLAULT]

This patch decodes the MAC/BB version (for instance: AR5416) and the RF
part version (for instance: AR5133). It has been tested on AR5416/AR5133
which is a 2.4/5GHz 3x3 11n device. It also makes the differences
between AR5416 (PCI) and AR5418 (PCI Express). Both are named AR5416 in
the register definitions.

I recommend adding a separate function returning the string instead of
this ugly "%s%s%s%s" trick. Much cleaner that way.

Agreed, also please remove 3x3 comment as we don't have support for
those yet nor do I even have hardware for it. To be clear ath9k supports
2x2 right now. :)

Hummm... This is what the Atheros web site says and I have 3 antennas
(very nice connector from UBNT btw). Of course, i don't know if it is
supported by the driver, but at least, I think, it's supported by the
hardware.

thanks, I'm going to test it on our later hardware, but patch fails
with git am (and therefore with patch itself):
