Last May we started working on cleaning up ath6kl driver which is currently in staging. The work has happened in a separate ath6kl-cleanup tree: http://git.kernel.org/?p=linux/kernel/git/kvalo/ath6kl-cleanup.git;a=summary After over 1100 (!) patches we have now reached a state where I would like to start discussing about pushing the driver to the wireless trees and replacing the staging driver. The driver is now a lot smaller and looks like a proper Linux driver. The size of the driver (measured with simple wc -l) dropped from 49 kLOC to 18 kLOC and the number of the .c and .h files dropped from 107 to 22. Most importantly the number of subdirectories reduced from 26 to zero :) There are two remaining checkpatch warnings in the driver which we decided to omit for now: drivers/net/wireless/ath/ath6kl/debug.c:31: WARNING: printk() should include KERN_ facility level drivers/net/wireless/ath/ath6kl/sdio.c:527: WARNING: msleep < 20ms can sleep for up to 20ms; see Documentation/timers/timers-howto.txt The driver has endian annotations for all the hardware specific structures and there are no sparse errors. Unfortunately I don't have any big endian hardware to test that right now. We have been testing the driver both on x86 and arm platforms. The code is also compiled with sparc and parisc cross compilers. Notable missing features compared to the current staging driver are: o HCI over SDIO support o nl80211 testmode o firmware logging o suspend support Testmode, firmware logging and suspend support will be added soon. HCI over SDIO support will be more difficult as the HCI driver needs to share code with the wifi driver. This is something we need to research more. Also I want to point out the changes I did for signed endian support. As I wasn't able to find any support for signed endian annotations I decided to follow what NTFS has done and added my own. Grep for sle16 and sle32, especially from wmi.h. Various people have been working on the cleanup, the hall of fame based on number of patches is: 543 Vasanthakumar Thiagarajan 403 Raja Mani 252 Kalle Valo 16 Vivek Natarajan 12 Suraj Sumangala 3 Joe Perches 2 Jouni Malinen Signed-off-by:

Currently ath9k presents the internal calibrated noise floor as channel noise measurement, however this results in highly chip specific values that are only useful as relative measurements but do not resemble any real channel noise values. In order to give a much better approximation of the real channel noise, add the difference between the measured noise floor and the nominal chip specific noise floor to the default minimum channel noise value, which is currently used to calculate the signal strength from the RSSI value. This may not be 100% accurate, but it's much better than what's there before. Signed-off-by:

This is needed to match wireless cards with Intersil firmware that have ID 0x0156:0x0002 and the third ID "Version 01.02". Such cards are currently matched by orinoco_cs, which doesn't support WPA. They should be matched by hostap_cs. The first and the second product ID vary widely, so there are few users with some particular IDs. Of those, very few can submit a patch for hostap_cs or write a useful bugreport. It's still important to support their hardware properly. With PCMCIA_DEVICE_MANF_CARD_PROD_ID3, it should be possible to cover the remaining Intersil based designs that kept the numeric ID and the "version" of the reference design. Signed-off-by:

According to 802.11-2007, 7.3.1.14 it is compliant to use a buf_size of 0 in ADDBA requests. But some devices (AVM Fritz Stick N) arn't able to handle that correctly and will reply with an ADDBA reponse with a buf_size of 0 which in turn will disallow BA sessions for these devices. To work around this problem, initialize hw.max_tx_aggregation_subframes to the maximum AMPDU buffer size 0x40. Using 0 as default for the bufsize was introduced in commit 5dd36bc9 (mac80211: allow advertising correct maximum aggregate size). Signed-off-by:

If we receive an ADDBA response with status code 0 and a buf_size of 0 we should stop the TX BA session as otherwise we'll end up queuing frames in ieee80211_tx_prep_agg forever instead of sending them out as non AMPDUs. This fixes a problem with AVM Fritz Stick N wireless devices where frames to this device are not transmitted anymore by mac80211. Signed-off-by:

For iwlwifi, I decided not to use this API since it just increased the complexity for little gain. Since nobody else intends to use it, let's kill it again. If anybody later needs to have it, we can always revive it then. Signed-off-by:

The previous P2P implementation turned out to not work well and new uCode capabilities were added to support P2P. Modify the driver to take advantage of those, and also discover P2P support automatically based on a uCode flag instead of having a Kconfig symbol for P2P. Signed-off-by:

The availability of contexts depends on the firmware capabilities. Currently only the presence of the second context depends on it, but soon P2P support will also be different. Move the context initialisation code to the firmware-dependent setup before registering with mac80211 to make it easier to handle. Signed-off-by:

We're working on improvements for the firmware for some devices, and need to bump the API for those since they won't be backward compatible completely (the earlier patch reserving queue 10 for P2P). Bump the API version to 6 for those devices but don't warn users of version 5 yet. Signed-off-by:

We sometimes need to support new firmware API for a while before we can publish them since testing them fully takes a long time. We could keep all the new code private, but that causes plenty of problems and sometimes we can give a pre-release version of firmware to people who need to test. However, when we just bump the API version, the driver will warn everybody that their firmware is outdated, when in fact it isn't. (Currently our case for this doesn't really change the API but bumping the API version is necessary because the firmware isn't fully backward compatible) In order to handle this in the future, add a new "api_ok" version; only below this will the driver warn that the uCode is too old.

New uCode images will use queue 10 for TX during scan (for P2P offchannel operation scan). We'll bump the API version of those, but before we need to reserve queue 10 and stop using it for aggregation. To simplify the code, always reserve it, we could continue using it on older uCode images but that'd be rather complicated. Also, we'll set it up to map to the right FIFO as needed later, but as we don't use the queue now that doesn't hurt. Signed-off-by:

Prepare bcm47xx to support different System buses. Before adding support for bcma it should be possible to build bcm47xx without the need of ssb. With this patch bcm47xx does not directly contain a ssb_bus, but a union contain all the supported system buses. As a SoC just uses one system bus a union is a good choice. Signed-off-by:
