The 5GHz bands were scanned without the proper IE's in place, preventing proper 5GHz scanning. This patches fixes the problem by storing a pointer to the scan request (with the IE's) for all iterations of scan. Signed-off-by:

A fixed 1 mbps rate was used for the PSM entry/exit null-func frames. Fix this by using the basic rates instead. Signed-off-by:

The core wl1271 module can also be used with SDIO, so it should not depend on SPI_MASTER. Signed-off-by:

The mac80211 changes to idle almost immediately after transmitting some frames, such as deauth etc. When going to idle, the wl1271 is disconnected, which causes TX frames already on buffers, but not yet transmitted, to be deleted. To make sure deauth frames reach the air, allow the TX buffers to flush before proceeding to idle. Signed-off-by:

As there is more and more stuff triggered by going in and out of idle, create a separate function for handling that. Signed-off-by:

The wl1271 uses a session counter in CMD_JOIN and TX frame descriptors. This counter is used to determine which frames to drop when the CMD_JOIN is executed. The driver executes CMD_JOIN multiple times upon association and sometimes disassociation, and we don't want any frames to get lost. Fix this by incrementing the session counter only when leaving idle (not every CMD_JOIN as before.) Also, remove the TX flush flag from the CMD_JOIN options. Signed-off-by:

We dereference "wmi" on the line before and also when we initialize "ah". This check has always been after a dereference since the first commit a couple months ago. Looking through the code, it looks like "wmi" can't actually be null here so I just removed the check. Signed-off-by:

When sending action frames, we want to verify that we do that on the correct channel. However, checking the channel type in addition can get in the way, since the channel type could change on the fly during an association, and it's not useful to have the channel type anyway since it has no effect on the transmission. Therefore, make it optional to specify so that if wanted, it can still be checked, but is not required. Signed-off-by:

It's our "private driver data"... It's used more often and hw is the mac80211 part. This makes more sense with the next (sysfs) patch. Signed-off-by:
-
Bruno Randolf authored
The old code logically did not make sense and seems to have been confused by the fact that we could have newer EEPROMs on older hardware. In any case the spur mitigation filter was set if the srev was >= AR5K_SREV_AR5424. Spur info is available only from EEPROM versions bigger than 5.3 but but the EEPOM routines will use static values for older versions, so that should be o.k. Signed-off-by:

Since NF calibration interferes with TX and RX and also has been the cause of other problems (when it's run concurrently with ath5k_reset) we want to run it less often - every 60 seconds for now. Signed-off-by:
-
Bruno Randolf authored
As far as we know, only NF calibration interferes with RX/TX so we can leave the queues enabled for the other calibrations. BTW: Stopping the queues is not enough for avoiding transmissions, since there might be packets in the queue + beacons are also sent regularly! But i leave it like this until we have a better solution (stopping TX DMA?). Signed-off-by:

Seperate noise floor calibration from other PHY calibration and move it to the tasklet. This is the first step to more separation of different calibrations. Also move out ath5k_hw_request_rfgain_probe(ah) so we have one clean function for I/Q calibration on 5111x parts. Signed-off-by:

This patch removes a large chunk of code dealing with rate management within the driver and simplifying things by removing the hacky method of calculating HT changes. A subsequent patch would fix this by just using BSS_CHANGED_HT from mac80211. Signed-off-by:
