2012-01-18ath6kl: add testmode 2 for 6003 ARTAlex Yang
Add testmode 2 for 6003 ART. When you insmod ath6kl_sdio.ko testmode=2, ath6kl will load ART firmware utf.bin and testscript nullTestFlow.bin. These files should be put in the firmware folder. kvalo: add "ath6kl:" to the title, word wrap the commit log and remove extra line in the code Signed-off-by: Alex Yang <xiaojuny@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2012-01-02ath6kl: Support for TCP checksum offload to firmwareRishi Panjwani
The change enables offloading TCP checksum calculation to firmware. There are still some issues with the checksum offload so better to disable it by default until the issues are resolved. To enable TCP checksum offload for tx and rx paths, use the ethtool as follows: ethtool -K <interface> tx on ethtool -K <interface> rx on To disable TCP checksum offload, for tx and rx paths, use the ethtool as follows: ethtool -K <interface> tx off ethtool -K <interface> rx off kvalo: indentation changes Signed-off-by: Rishi Panjwani <rpanjwan@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-12-23ath6kl: add support for FW API 3Kalle Valo
As firmware starting from 3.2.0.12 has some API changes and doesn't work with older versions of ath6kl we need to bump up the API version. This way we don't break anything. Also store which version of API is used and print that during boot: ath6kl: ar6003 hw 2.1.1 sdio fw 3.2.0.13 api 3 Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-12-23ath6kl: handle firmware names more dynamicallyKalle Valo
Currently ath6kl has just hardcoded paths to each firmware file. Change this more dynamic by separating the the directory and file name from each other. That way it's easier to dynamically create full paths to firmware and code looks better. And now it's possible to remove a function needed by devicetree code. While at it add a structure inside struct ath6kl_hw to contain all firmware names. I deliberately omitted board file support as those will be handled later. This is needed for firmware API 3.

2011-12-13ath6kl: implement scheduled scanKalle Valo
ath6kl firmware supports scheduled scan functionality with the wow ssid filter. But the firmware does not send any events after scan results so I had to add a timer which notifies about new scan results. Sched scan needs firmware version 3.2.0.6 or later. If firmware doesn't support sched scan the driver will not enable the feature. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-12-13ath6kl: fix reading of FW IE capabilitiesKalle Valo
For some strange reason I used ALIGN() to calculate index to the buffer. That is totally bogus and wouldn't work when it tried to read the second bit. Fix it by removing the ALIGN() altogether. Also check that ie_len is not too short. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

Currently the max number of vifs which can be used for non-p2p mode is determined in ath6kl_core_alloc(). But the maximum supported vifs are parsed from firmware IE in ath6kl_fetch_fw_api2() which would happen after ath6kl_core_alloc().

2011-11-16ath6kl: add firmware IE for maximum number of vifsKalle Valo

2011-11-16ath6kl: use hardware version names consistentlyKalle Valo
Part of ath6kl uses "REV3" style of naming hardware versions and elsewhere "hw 2.1.1" is used instead for the same version. This is confusing, use the latter term everywhere. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-16ath6kl: add name field to struct ath6kl_hwKalle Valo
To make it easier to print name for each hardware type. Also move the hw info print to ath6kl_init_hw_start() which is more logical place for it. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-16ath6kl: add firmware IE for board data addressKalle Valo
Board data address can change between firmwares so we need to read that from the firmware image. Also fix debug log for the patch address to print the address in hex. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-16ath6kl: add board address to struct ath6kl_hwKalle Valo

2011-11-16ath6kl: remove hw version related parameter definesKalle Valo
Having separate defines, in a different file, makes it difficult to read the actual values. As we are just setting named fields in a struct the defines don't make any sense anymore. There are no functional changes, only moving of constants. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2011-11-11ath6kl: add suspend_cutpower module parameterKalle Valo
This is to force ath6kl to power off hardware during suspend even if sdio support keep power. This is needed, for example, when sdio controller is buggy or maximum powersaving is desired. Usage: insmod ath6kl.ko suspend_cutpower=1 Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-11ath6kl: don't power down hardware when interface is downKalle Valo
Jouni reported that my patch "ath6kl: power down hardware when interface is down" caused a regression on his x86 boxes and scan didn't work anymore. I was able to reproduce the problem by disabling all debug messages. So there has to be a race condition somewhere in the code and disable the functionality until the race is fixed. Now hardware is powered from the point where module is loaded until it's removed.

2011-11-11ath6kl: power down hardware when interface is downKalle Valo
The benefit from this is that user space can control hardware's power state by putting interface up and down. This is handy if firmware gets to some weird state. The downside will be that putting interface up takes a bit longer, I was measuring ~500 ms during interface up. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
