* iwlwifi: fix rate control regressionMoshe Benji2013-06-12
| | | | | | | | | | | | | Since driver does not use control.rates[0].count, we have never set that variable. But currently, after rate control API rewrite, this is required by mac80211. Otherwise legacy rates control does not work and we transmit always at 1Mbit/s on pre 11n networks. [same fix as for iwlegacy, thanks Stanislaw!] Signed-off-by: Moshe Benji <Moshe.Benji@intel.com> Reviewed-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

* iwlwifi: mvm: fix aggregation drain flowEmmanuel Grumbach2013-05-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | Move the counter for non-AMPDU frames to mvm. It is needed for the drain flow which happens once the ieee80211_sta has been freed, so keeping it in iwl_mvm_sta which is embed into ieee80211_sta is not a good idea. Also, since its purpose it to remove the STA in the fw only after all the frames for this station have exited the shared Tx queues, we need to decrement it in the reclaim flow. This flow can happen after ieee80211_sta has been removed, which means that we have no iwl_mvm_sta there. So we can't know what is the vif type. Hence, we know audit these frames for all the vif types. In order to avoid spawning sta_drained_wk all the time, we now check that we are in a flow in which draining might happen - only when mvmsta is NULL. This is better than previous code that would spawn sta_drained_wk all the time in AP mode.

* iwlwifi: mvm: Prevent setting assoc flag in MAC_CONTEXT_CMDAlexander Bondar2013-05-16
| | | | | | | | | | | | | | In the normal flow first MAC_CONTEXT_CMD for particular interface is never sent while associated. The exception is fw restart flow when resuming from suspend when WoWLAN is enabled. In this case successive "add" and "modify" MAC_CONTEXT_CMD commands may be sent with assoc flag set what cause FW mal functioning. To prevent this never set assoc flag in MAC_CONTEXT_CMD with action "add".
