Re: [PATCH wireless-next 2/3] ath5k: Introduce _ath5k_printk to reduce code/text

Hi,

So the reason this is a macro in the FreeBSD HAL is so that the args
aren't evaluated unless the level (or debug bitmap in my case) fires
off.

Otherwise compiling in debugging will cause a _lot_ of spurious
register reads to occur that are then tossed. This was one of the big
reasons for instability and slow performance when AH_DEBUG was
enabled.
