2011-01-25ath5k: ath5k_setup_channels cleanup and whitespaceBruno Randolf1-8/+3
Remove useless test_bit - it's not going to happen because of the way this function is called only when that bit is set. And fix some whitespace.

Also the ath5k_rate_update which is refered to in the comment does not exist (any more?) so we don't need to setup the band in that place.

2010-12-22ath5k: Track current TX power separately from max TX powerBruno Randolf2-4/+4
Add a new variable to keep track of the currently configured tx power. Before max_pwr was re-used for keeping the maximum allowed power as well as the current configuration. Doing a min() on it allows you to lower the txpower, but how would you be able to make it higher again? This patch fixes that by adding a new variable ah_cur_pwr which is used instead of txp_max_pwr to keep the current configuration. txp_max_pwr is used to check if we are within the limits. Another problem fixed by this patch is that it avoids setting a zero txpower when things are initialized first and the current power is not yet set.

2010-12-16ath5k: Fix surveyBruno Randolf2-12/+25
The old survey implementation was broken and returned nonsense data. Clear cycle counters and survey data on reset. Since the cycle counters easily overflow it's better to keep a local version of collected survey data (in ms resolution, instead of clockrate) and update this every time survey is retrieved. If survey is retrieved often enough to avoid cycle counter overflows this works fine, otherwise we could update survey more often, like ath9k does. Still only the survey for the current channel is kept. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-12-06ath5k: Always free tx buffers before resetNick Kossifidis1-2/+4
* Always free tx buffers before reset, since we also empty hw queues. If we don't and a queue gets stuck, we'll never decrease txq_len and sw will keep thinking the queue is still stuck even after reset.

2010-12-06ath5k: Always write tx powertable on hwNick Kossifidis1-12/+21
* By skipping tx power table calibration we also skip setting tx power table on hw. Make sure we always write tx power table on hw since it gets cleared on reset.

2010-11-30ath5k: Set turbo bit on rf bank 2Nick Kossifidis2-3/+29
* A diff between rfbuffer settings of turbo and non-turbo modes indicates there is a bit on bank 2 related to turbo operation (it's set on turbo modes). This bit is present on all radios except RF5413 that seems to have a completely different bank 2. Also since 2317 has the same rf-registers locations with 2425 and since the bit exists on 2317 I assume it also exists on 2425/2417). So in case we use turbo mode (40MHz) enable it on bank modification. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
