There are connection stalls or very poor throughputs with rt2800 hardware using 802.11n in AP mode since patch "mac80211: retry sending failed BAR frames later instead of tearing down aggr"[1][2]. Since rt2800 hardware is not able to correctly report the tx status of BAR frames, this patch removes as workaround the existing error handling on AP side, which lets mac80211 send a BAR when an AMPDU subframe fails. As a result, most wifi clients (aside from Intel STAs on Windows) instead will timeout now the reorder buffer and request the lost frame again. The correct solution would be, to tear down BA session on AP side. This patch was born on the basis of "[RFT] rt2x00: Tear down BA session on QoS frame failure"[3]. Thanks to Helmut Schaa for his support!

The existing constants are used for reduction/increase tx power level on devices with 2x2 and 3x3 chainmask. Both reduction and increase must use the same value, so it makes no sense to use separate constants for them. Signed-off-by:

The command strings are needed through the layers for debug and error messages, but can differ with opmode. As a result, we need to give the command names to the transport layer as configuration. Signed-off-by:

We've never released firmware using the alternatives mechanism and our build process makes that difficult anyway. This means that in every file we have ever built (except maybe by hand for testing) the listed alternative was 0. Make the alternative field in the TLVs part of the TLV number (thus expanding that to 32 bits); this gives us more TLV numbers (not really needed) and more importantly protects against rogue firmware files that actually do use the alternatives mechanism -- those will now be rejected since they don't contain any valid TLVs.

My original idea with this was to adjust the sleep pattern of the uCode based on the maximum network latency userspace asked for. Due to nobody wanting to test it, this logic was disabled by default. It seems the time has come to remove it, since it's not only always disabled but there also don't seem to be any applications that actually request a max network latency. Signed-off-by:

The REDUCE_SCALED_POWER_BY_THREE_CHAIN symbol is defined in different eeprom files, and the value varies between the different files. In eeprom_def.c and in ar9003_eeprom.c the value of the symbol is 9, however the comments in these files indicates the value should be 10*log10(3)*2 which is 9.54242509439325. Replace the the value to 10 in these files. Also add comments to eeprom_9287.c. Signed-off-by:

The background scan completion takes more time when the station is having heavy uplink traffic. The scan state machine decides to fall back to home channel on every off-channel visit when there are pending frames in tx queue. bgscan completion took ~30sec on dual band US regulatory card. scan period = (20 active channels * probe timeout) + (12 passive channels * passive probe timeout) + (32 * timeout on home channel) + (32 * flush timeout) Signed-off-by: -

Sync-up ibss beacon timer with the beacon frame's timestamp. When the node acts as joiner, it has to sync with the received beacon timestamp instead of reading tsf from hw.

When testing mesh synchronization we observed a global TSF slowdown that was dependent on the number of synchronized mesh stations. This seems to be caused by the TSF adjustment (read/write) latency. Adding a small margin to the Toffset setpoint solved the problem. Signed-off-by:
