The C99 specification states in section 6.11.5: The placement of a storage-class specifier other than at the beginning of the declaration specifiers in a declaration is an obsolescent feature.

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: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

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 <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

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.

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 <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

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: Bruno Randolf <br1@einfach.org> Acked-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.

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.

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.

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.

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.

In suspend() host sleep is activated using already configured host sleep parameters through wol command, and in resume() host sleep is cancelled. Earlier priv->fw_ready flag used to reset and set in suspend and resume handler respectively. Since after suspend only host goes into sleep state and firmware is always ready, those changes in flag state are removed. Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: John W.
