madwifi/ath_hal/ah_os.c
proski 200f8b8a6a Fix compilation with HAL_DEBUG=1 
Provide forward declaration of struct ath_hal in ah_osdep.h.  Implement
OS_GETUPTIME (the implementation is quite primitive, as it's only used
once for some obscure condition in 5212 chips).  Implement HALDEBUG()
and ath_hal_ether_sprintf().
