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. Signed-off-by:

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). Signed-off-by:

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.

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. Signed-off-by:

Since commit d1c3a37c ("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alignment docs, fix up alignment") removed the requirement for a 4-byte aligned payload rt2x00queue_align_payload is obsolete as mac80211 will align the payload when it passes the frame to the net stack.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). Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

The only thing that using crypto_blkcipher with ecb does over just using arc4 directly is wrapping the encrypt/decrypt function into a for loop, looping over each individual character. To be able to do this, it pulls in around 40 kb worth of unnecessary kernel modules (at least on a MIPS embedded device). Using arc4 directly not only eliminates those dependencies, it also makes the code smaller. Signed-off-by:

The commit "mac80211: reply to directed probes in IBSS" changed ad-hoc specific code to respond to unicast probe requests, even if drv_tx_last_beacon returns false, however due to confusion over the meaning of the IEEE80211_RX_RA_MATCH flag, it also unconditionally enabled responding to multicast probe requests. Fix this by explicitly checking for a multicast destination address instead. Signed-off-by:
