* mac80211: freeing the wrong variableDan Carpenter2010-07-26
| | | | | | | | The intent was to free "msp->ratelist" here. "msp->sample_table" is always NULL at this point. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* minstrel_ht: remove unnecessary NULL check in minstrel_ht_update_capsJohn W. Linville2010-07-26
| | | | | | | | If sta is NULL, we will have problems long before we get here... Reported-by: Dan Carpenter <error27@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com> Cc: Felix Fietkau <nbd@openwrt.org>
* minstrel_ht: fix check for downgrading of top2 rateMing Lei2010-07-02
| | | | | | | | | The check should be against current top2 rate, instead of current top rate. Signed-off-by: Ming Lei <tom.leiming@gmail.com> Acked-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* minstrel_ht: fix updating rate with best probabilityMing Lei2010-07-02
| | | | | | | | | The throughput should be considered when updating rate with best probability. Signed-off-by: Ming Lei <tom.leiming@gmail.com> Acked-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* mac80211: use RCU for TX aggregationJohannes Berg2010-06-14
| | | | | | | | | | | | | Currently we allocate some memory for each TX aggregation session and additionally keep a state bitmap indicating the state it is in. By using RCU to protect the pointer, moving the state into the structure and some locking trickery we can avoid locking when the TX agg session is fully operational.
