2009-04-22iwlwifi: adding MIMO3 support in rate scalingWey-Yi Guy
Separated the MIMO tpt matrix into MIMO2 and MIMO3, adding MIMO3 support in rate scaling algorithm. If the device support 3x3, then utilize all three antenna (A/B/C) for tx to improve throughput. Adding rs_switch_to_mimo3() function to allow switch to mimo3 modulation mode from other modes(legacy/siso/mimo2). Adding rs_move_mimo3_to_other() function to allow switch from mimo3 modulation mode to either siso or mimo2; also support toggle between SGI and NGI.

2009-04-22cfg80211: introduce scan IE limit attributeJohannes Berg
This patch introduces a new attribute for a wiphy that tells userspace how long the information elements added to a probe request frame can be at most. It also updates the at76 to advertise that it cannot support that, and, for now until I can fix that, iwlwifi too. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-04-22iwlwifi: change check triggering device restart after rfkill changeReinette Chatre
The STATUS_ALIVE value cannot be used because it is cleared when interface is brought down and will not be set if rfkill is enabled when interface is started again. The interface can thus not be brought up if rfkill was enabled before stopping the interface and disabled after starting the interface. Change the test to use priv->is_open instead, this will be set when interface is started whether rfkill is enabled or not. Thanks to Helmut Schaa for the suggested fix.

2009-04-22rfkill: remove user_claim stuffJohannes Berg
Almost all drivers do not support user_claim, so remove it completely and always report -EOPNOTSUPP to userspace. Since userspace cannot really drive rfkill _anyway_ (due to the odd restrictions imposed by the documentation) having this code is just pointless.

2009-03-27mac80211/iwlwifi: move virtual A-MDPU queue bookkeeping to iwlwifiJohannes Berg
This patch removes all the virtual A-MPDU-queue bookkeeping from mac80211. Curiously, iwlwifi already does its own bookkeeping, so it doesn't require much changes except where it needs to handle starting and stopping the queues in mac80211. To handle the queue stop/wake properly, we rewrite the software queue number for aggregation frames and internally to iwlwifi keep track of the queues that map into the same AC queue, and only talk to mac80211 about the AC queue. The implementation requires calling two new functions, iwl_stop_queue and iwl_wake_queue instead of the mac80211 counterparts.

IEEE80211_TX_CTL_AMPDU was set by mac80211 for aggregation pkt. But when iwlwifi receive the tx status reply, it reset the flag to following info->flags = IEEE80211_TX_STAT_ACK; info->flags |= IEEE80211_TX_STAT_AMPDU; it causes the rate-scaling to not work for aggregation pkt if we checking for IEEE80211_TX_CTL_AMPDU flag.
