* iwlwifi: move DVM code into subdirectoryJohannes Berg2012-06-061-432/+0
| | | | | | | | | | Since we're working on another mode/driver inside iwlwifi, move the current one into a subdirectory to more cleanly separate the code. While at it, rename all the files.

* iwlwifi: properly set basic ratesJohannes Berg2012-04-231-26/+0
| | | | | | | | | | | | This fixes a long-standing bug: iwlwifi always assumes that the CCK ACK rates are 1 and 2 MBps and the OFDM ACK rates are 6, 12 and 24 MBps. Fix this problem by using the basic rates the AP (or in AP case hostapd) told us to use and add the necessary mandatory rates to the mix.

* iwlwifi: fix default LQ table in 5.2 bandTomas Winkler2010-09-111-9/+0
| | | | | | | | | | | | | | | | | | | | | The default LQ is filled decreasingly using iwl_get_prev_ieee_rate from a starting rate. Since the starting rate is already the lowest one for a specific band it should be actually filled evenly with the starting rate: 1M and 6M for 5.2GHZ and 2.4GH respectively. The bug is that for for A or G-only it decreases to CCK rates which are not supported. iwl_get_prev_ieee_rate function is just not band aware. This affects broadcast station which lq table is not updated by rs algorithm G-only scenario is not treated by this patch iwl_get_prev_ieee_rate is removed completely as it is not used in other contexts Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
* iwlagn: let bluetooth traffic load impact rate scaleJohannes Berg2010-08-251-0/+2
| | | | | | | | | | | | | | | | | | | | | | Depending on the amount of bluetooth traffic, using the shared antenna (antenna B) will have adverse impact on both bluetooth and wireless traffic. Add controls to improve the situation by making rate scaling depend on the BT load. When there's high bluetooth traffic load, there's little point in trying to aggregate as BT traffic would disrupt the aggregated frames all the time, so simply don't start sessions then. When BT traffic returns to lower levels, the rate scaling will come here again automatically when wifi traffic is high enough, and then it will be able to successfully enable aggregation.

* iwlwifi: implement new mac80211 station add/remove callsReinette Chatre2010-03-191-1/+6
| | | | | | | | | | | | | | mac80211 recently implemented two new callbacks that are used to request station add/remove from the driver. The benefot from these new callbacks are that they enable the driver to sleep while performing this work. This is a big patch since a few things need to be coordinated in this move. First we need to decouple station management from rate scaling, which caused a lot of code to be moved and/or deleted. Next we needed to tie in with mac80211's station management callback and let it direct our station management as well as trigger the rate scaling initialization.

* iwlwifi: remove 60 Mbps from sband bitrates tableDaniel C Halperin2009-08-311-0/+1
| | | | | | | | | | | | ieee80211_supported_band is supposed to only contain legacy rates in the bitrates table (HT rates go in the ieee80211_sta_ht_cap substruct). Make iwlwifi driver obey this restriction by removing the 60 Mbps rate. Also, clean up a few pieces of other code that formerly relied on 60 Mbps being in sband->bitrates.

* iwlagn: improve rate scale table searchMohamed Abbas2009-05-111-0/+2
| | | | | | | | | | | | | | iwlagn rate scaling will periodically search other rate scale tables to switch to the best table regarding performance. In the past the number of search tables were 3. Every time the rate scale algorithm goes through these available tables in will stay in current table for some time before start searching again. Recent driver support more feature and antenna, so we have more tables to search. This patch make sure we go through all available tables.

* iwlwifi: adding MIMO3 support in rate scalingWey-Yi Guy2009-04-221-0/+18
| | | | | | | | | | | | | | | 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.

* iwlwifi: HT performance improvement changesWey-Yi Guy2009-03-161-1/+1
| | | | | | | | | | | | During rate scaling, checking for 0 retry count before decrement the count by 1, this can avoid the retry count to become 255 (0xff), which will cause the rate to drop faster than what we expect during good condition (receive 0 retry packet). also change the algorithm to make the rate not drop faster than what we like.
