* This file provides some macros that are used by if_ath_hal.h,
|
|
* if_ath_hal_wrappers.h, and if_ath_hal_wrappers.c.
|
|
*
|
|
* The macros are provided for the HAL lock and for dynamically deciding whether
|
|
* to define the HAL wrapper functions as inline or in the implementation file
|
|
* at build time. i.e. inline for speed, or non-inline for debugging visibility
|
|
* into the HAL methods being called (despite obfuscation).
|
|
*
|
|
* The if_ath_hal.h file is generated from hal/ah.h at build time by the build
|
|
* system.
