ath9k_rx_skb_preprocess() needs only ieee80211 frame header, pass only frame headers instead of skb to that function. Also remove ineffective frame dump in ath9k_process_rate(). Signed-off-by:

This patch relocates RX processing code from the common module to ath9k. This reduces the size of the common module which is also used by ath9k_htc. 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:

Since we have sysfs to manually set the ANI levels, we should print errors to the kernel log if the values are out of bounds. Signed-off-by:

Calculate 'listen' time also when automatic ANI is off, since this and the "busy" time is useful information also in manual mode. 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:

Initialize calibration timers on reset, since otherwise they might be in the future and the calibration tasklet might not be scheduled for a long time. Signed-off-by:

Buffer size for get_association_info was limited to WEXT event size. Since association info no longer is sent through WEXT, this limit is not needed. Code also did not check if data get truncated, memory outside buffer might be addressed. Fix all these. Signed-off-by:

Use BSS_CHANGED_HT to handle HT parameter changes. The rate information on the target has to be updated to handle changes in HT configuration. Signed-off-by:
-
Sujith authored
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:

The snprintf() function returns the number of bytes that *would* have been written (not counting the NULL terminator) and that can potentally be more than the size of the buffer. In this patch if there were one liners where string clearly fits into the buffer, then I changed snprintf to sprintf(). It's confusing to use the return value of snprintf() as a limitter without verifying that it's smaller than size. This is what initially caught my attention here. If we use the return value of sprintf() instead future code auditors will assume we've verified that it fits already. Also I did find some places where it made sense to use the return value after we've verified that it is smaller than the buffer size. Finally the read_file_rcstat() function added an explicit NULL terminator before calling snprintf(). That's unnecessary because snprintf() will add the null terminator automatically. Signed-off-by:
