* use only one debug level for beacon debugging: unify ATH5K_DEBUG_BEACON and ATH5K_DEBUG_BEACON_PROC. * remove debug level ATH5K_DEBUG_FATAL. doesn't make sense as a debug level - if it's fatal it should be logged as an error. * fancier printing of debug levels. cat /debugfs/ath5k/phy0/debug. * allow debug levels to be changed by echoing their name into /debugfs/ath5k/phy0/debug. this will toggle the state, when it was off it will be turned on and vice versa. * use copy_from_user() when reading from the debug files. use unsigned int for better optimization. reduce buffer sizes on stack. drivers/net/wireless/ath5k/base.c: Changes-licensed-under: 3-Clause-BSD drivers/net/wireless/ath5k/debug.c: Changes-licensed-under: GPL drivers/net/wireless/ath5k/debug.h: Changes-licensed-under: GPL Signed-off-by: Bruno Randolf <bruno@thinktube.com> Acked-by: Luis R.
