 * @ATH_DBG_EEPROM: eeprom processing
 * @ATH_DBG_CALIBRATE: periodic calibration
 * @ATH_DBG_INTERRUPT: interrupt processing
 * @ATH_DBG_REGULATORY: regulatory processing
 * @ATH_DBG_ANI: adaptive noise immunitive processing
 * @ATH_DBG_XMIT: basic xmit operation
 * @ATH_DBG_BEACON: beacon handling
 * @ATH_DBG_CONFIG: configuration of the hardware
 * @ATH_DBG_FATAL: fatal errors, this is the default, DBG_DEFAULT
 * @ATH_DBG_PS: power save processing
 * @ATH_DBG_HWTIMER: hardware timer handling
 * @ATH_DBG_BTCOEX: bluetooth coexistance
 * @ATH_DBG_BSTUCK: stuck beacons
 * @ATH_DBG_ANY: enable all debugging
 *
 * The debug level is used to control the amount and type of debugging output
 * we want to see. Each driver has its own method for enabling debugging and
 * modifying debug level states -- but this is typically done through a
 * module parameter 'debug' along with a respective 'debug' debugfs file
 * entry.
