If you´re looking for a Linux driver for your Atheros WLAN device, you should continue here .

NOTE: This list comes directly from the defines in the ath5k driver. It is used for various debugging and reverse engineering tools and conversion scripts as well as for public reference. Please add any information you have about these registers and add them if you find out the meaning of new registers! Take care, however that you don't violate any NDAs and don't include information from illegal sources!

  • ADDRESS: is the register address
  • NAME: is the name of the #define as used in the current ath5k/regs.h
  • CHIPS: is a comma separated list of chipsets this information applies to. if empty it means "all" chipsets, 5212+ means for 5212 upwards
  • NOTES: Notes about the usage of this register
