ath-info is a tool to provide various information (mostly EEPROM contents) on atheros wi-fi cards (for now only AR5xxx series -not 11n-). It can also manipulate and save/restore EEPROM contents.
This tool was mainly used durring the rev. engineering process of the Atheros drivers, while working on madwifi-old-openhal and later ath5k. It can be used for experimentation, debuging etc.
