* Register values for Atheros 5210/5211/5212 cards from OpenBSD's ar5k

*
* I tried to document those registers by looking at ar5k code, some
* 802.11 (802.11e mostly) papers and by reading various public available
* Atheros presentations and papers like these:
*
* 5210 - http://nova.stanford.edu/~bbaas/ps/isscc2002_slides.pdf
*
* 5211 - http://www.hotchips.org/archives/hc14/3_Tue/16_mcfarland.pdf
*
* This file also contains register values found on a memory dump of
* Atheros's ART program (Atheros Radio Test), on ath9k, on legacy-hal
* released by Atheros and on various debug messages found on the net.

* renamed it to SNAPSHOTSVALID to make more sense. I really have no idea what
