2011-04-07iwlwifi: remove sync_cmd_mutexStanislaw Gruszka
We now use priv->mutex to serialize sync command, remove old priv->sync_cmd_mutex and add assertion that priv->mutex must be locked. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Acked-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-04-07iwlwifi: more priv->mutex serializationStanislaw Gruszka
Check status bits with mutex taken, because when we wait for mutex unlock, status can change. Patch should also make remaining sync commands be send with priv->mutex taken. That will prevent execute these commands when we are currently reset firmware, what could possibly cause troubles.

2011-04-07iwlwifi: fix enqueue hcmd race conditionsStanislaw Gruszka
We mark command as huge by using meta->flags from other (non huge) command, but flags can be possibly overridden, when non huge command is enqueued, what can lead to: WARNING: at lib/dma-debug.c:696 dma_debug_device_change+0x1a3/0x1f0() DMA-API: device driver has pending DMA allocations while released from device [count=1] To fix introduce additional CMD_MAPPED to mark command as mapped and serialize iwl_enqueue_hcmd() with iwl_tx_cmd_complete() using hcmd_lock. Serialization will also fix possible race conditions, because q->read_ptr, q->write_ptr are modified/used in parallel. On the way fix whitespace.

2011-04-04rt2x00: Add an error message when trying to send on a full queueHelmut Schaa
We already tell mac80211 to stop the queue when we hit a certain threshold. Hence, it shouldn't happen at all that a frame gets queued for tx on a full queue. Add an error message for this case.

2011-04-04rt2x00: Fix tx aggregation problems with some clientsHelmut Schaa
Some clients seem to rely upon the reception of BlockAckReqs to flush their rx reorder buffer. In order to fix aggregation for these clients rt2x00 should send a BlockAckReq if the transmission of an AMPDU subframe fails. Introduce a new flag TXDONE_AMPDU to indicate that this is an AMPDU subframe and pass IEEE80211_TX_STAT_AMPDU_NO_BACK to mac80211 if an AMPDU subframe failed during transmission. This fixes aggregation problems with Intel 5100 Windows STAs (and maybe others as well).

2011-04-04rt2x00: Fix STBC transmissions to STAs with Rx STBC > 1Helmut Schaa
For STBC transmissions rt2x00 used the number of RxSTBC streams the destination STA indicates in its HT capabilities as STBC value in the TXWI. However, the legacy drivers and our own comment in rt2800.h suggest that the STBC field in the TXWI only allows a value of 0 or 1. The values 2 and 3 are reserved (probably for future devices). And indeed, STBC transmissions to STAs indicating more then 1 RxSTBC stream fail when the STBC field is set to something >1. Fix this by only setting the STBC field to 1 when STBC should be used.

2011-04-04rt2x00: Implement tx power temperature compensationHelmut Schaa
rt2800 devices should adjust their tx power in accordance with the eeproms temperature calibration values. Add a new driver callback gain_calibration that is called every 4 seconds. The rt2800 gain calibration routine simply runs the tx power configuration that takes care of calculating the temperature compensation delta. We don't need to synchronize the calls to rt2800_config_txpower as they should all happen from mac80211's single threaded workqueue.

2011-04-04rt2x00: Remove obsolete rt2x00queue_align_payloadHelmut Schaa
Since commit d1c3a37ceeb1a5ea02991a0476355f1a1d3b3e83 ("mac80211: clarify alignment docs, fix up alignment") removed the requirement for a 4-byte aligned payload rt2x00queue_align_payload is obsolete as mac80211 will align the payload when it passes the frame to the net stack. As a result we can remove the call to rt2x00queue_align_payload in the rx path and since that's the last user we can remove rt2x00queue_align_payload altogether. One advantage is that we save some alignment operations for frames that don't need to be aligned (for example beause they are not passed to the net stack).

2011-04-04rt2x00: Calculate tx status fifo size instead of hardcoding itHelmut Schaa
Instead of hardcoding the tx status fifo size as 512 calculate it based on the number of tx queues and the number of entries per queue. Also round the size up to a power of 2 as kfifo would otherwise round it down. On rt2800pci this will increase the kfifo size from 512 bytes to 1024 bytes which is then able to hold the tx status for all entries in all tx queues. Furthermore, if the number of tx queues or tx entries changes in the future (use of the MGMT queue for example) the kfifo size doesn't need to be updated.

2011-04-04mwifiex: use IEEE80211_HT_CAP_ macros for 11n cap_infoMarc Yang
The hw_dot_11n_dev_cap reported by firmware hw_spec has different format than the 11n capabilities. Hence a lot of SET_ and RESET_ bit operation macros were used to convert the dev_cap format to 11n capability format. However the locally defined 11n ht_cap macros are not necessary as we can use IEEE80211_HT_CAP_ macros directly. The 32-bit dev_cap bitmap is added as comment to explain the mapping between firmware and 11n spec. Some unused macros and unnecessary adapter variables are also removed.
