2011-10-13cw1200: Requeue special frames.Dmitry Tarnyagin
Some frames require special handling in wsm, for example offchannel, wep, join... Requeue for offchannel and wep frames was missing, leading to queue entry leakage and unexpected drop of frames. Fix implements requeue for special frames.

2011-10-13cw1200: AP PS refactoring.Dmitry Tarnyagin
* buffered_multicasts_lock was renamed to ps_state_lock. Previous name was quite confusive. * Per-STA rx_queue was created for early RX-ed frames. Not that we really need these frames, but PM status they are holding is important. * priv->tx_suspend_mask was removed, driver is not using it. It was intended for UAPSD and is not needed in current implementation on mac80211. * Fix: cw1200_queue_unlock() was not called from cw1200_queue_clear() when queue was internally locked.

TODO: - Verify A-MPDU factor settings in cw1200_band_2ghz. SKB cache is implemented. Firmware loading refactoring. + CUT 2.0 detection is implemented. + Standard firmware loading API is used. + Firmware loading path is changed to /lib/firmware/cw1200/ + Firmware is put to the project: ./firmware/ TODO: - Firmware copying at build time. Bringup after mainlining. + FW downloading is working now. TODO: - BH thread can't read data block from device. Init: removing GPIO toggling. Not needed anymore. WLAN: Fix for missing GPIO_HIGH, GPIO_LOW The patch defines CW1200_GPIO_{HIGH|LOW} as replacement of GPIO_{HIGH|LOW}, which might be absent on the target platform. Also it allows build without compat wireless tree. Added cw1200 to drivers/staging Kconfig and Makefile. Added two CONFIG_ flags: + CONFIG_CW1200 - Enables the generic cw1200 module + CONFIG_CW1200_U8500_PLATFORM - U8500 platform integration Removed binary firmware files, they do not belong in the kernel tree. Added TODO file for cw1200 staging driver. Added more help text to Kconfig Removed checkpatch warnings. There is still one left. Removed all checkpatch warnings for cw1200.h Removed checkpatch warnings from cw1200_stdio.c. There is still one left. Removed checkpatch warnings for fwio.h Removed checkpatch warning for hwio.c Removed checkpatch warnings for main.c There are still some warninges left. Removed checkpatch warnings from queue.c There are still some warnings left Removed checkpatch warnings for queue.h Removed checkpatch warnings for sbus.h Removed checkpatch warnings for scan.c Removed checkpatch warnings for scan.h Removed checkpatch warnings for sta.c Removed checkpatch warnings for txrc.c Removed checkpatch warnings for txrx.h Removed checkpatch warnings from wsm.c Lots of "line over 80 char..." warnings left. Minor checkpatch warning cleanup on wsm.c WLAN: CW1200: Development: SoftAP mode WLAN: CW1200: AP development. + Basic open AP is woking (prototyping done). TODO: - Check AP scan & assoc with sniffer - WSM API: TxPowerLevel in scan requests. - WSM API: Frame in TX and RX indication. - WSM API: Flags in set_bss_params. - WSM API: IGTKGroupKey in key info. - WSM API: MultiTX confirm - WSM API: Config block ACK - WSM API: BA timeout indication. CW1200: WLAN: Fix for a merge error. This commit fixes build error introduced by WLAN: CW1200: AP development. WLAN: CW1200: Fix for a warning in net/mac80211/rx.c WLAN: CW1200: Add / remove key refactoring for AP mode. Keys are cached in the driver and loaded after wsm_start() is called. Verified (AP mode): + Open security: OK + WEP40: OK + WEP104: FAIL (WSM_STATUS_DECRYPTFAILURE) + CCMP: FAIL (MIC failure detected by STA. STA->AP decrypted OK) + TKIP: FAIL (MIC failure detected by STA. STA->AP decrypted OK) WLAN: CW1200: Proper handling of stop request in the AP mode. WLAN: CW1200: Firmware-driven keep-alive is implemented. CW1200: SDIO card detection is implemented. Removed dependency to u8500_sdio_detect_card(). New moule parameter "device" is implemented to point to the SDIO interface device is connected to. WLAN: CW1200: Checkpatch cleanup. + wsm.c is cleared. + sta.c is cleared. + ap.c is cleared. + bh.c is cleared. + cw1200_sdio.c is cleared. + main.c is cleared. + queue.c is cleared. + scan.c is cleared. + txrx.c is cleared. + cw1200.h is cleared. + hwio.h is cleared. + ht.h is cleared. + wsm_get_tx is (finally!) redesigned. TODO: - wsm.h WLAN: CW1200: Checkpatch cleanup. + wsm.h is cleared. Code is ready for submission. WLAN: CW1200: Module parameter for MAC address. New module parameter for cw1200_core.ko: "macaddr". Usage: modprobe cw1200_core macaddr=0x00,0x80,0xE1,0x30,0x40,0x50 Random MAC address by default. WLAN: CW1200: Fix for a crash in skb_release_data(). WLAN: CW1200: Fix for a too short WSM timeout in stressed condition. WLAN: CW1200: Bugfix after regression testing. Datapath is verified (several gigabytes of downloaded data). WLAN: STA mode development. + AP API sta_add/sta_semove is implemented. + wsm_suspend_resume_indication is implemented. + Unique link ID is allocated for STAs in AP mode as WSM requires. + wsm_map_link is implemented. + wsm_reset is modified to support multiple link IDs. + cw1200_suspend_resume handler is implemented in the ap.c. + no more hardcoded SSIDs + Debug logs functionality is exposed to the kernel config. + Suspend / resume is supported by queue. + TKIP multicast TX (AP mode) is fixed. TODO: - AP mode with powersave is not verified. WLAN: Support for non-power-of-two SDIO transfer. WLAN: AP mode verification and bugfixing. + Fix for broken broadcasts. + Redesign of PS implementation in AP mode. + set_tim() is implemented. + sta_notify() is implemented. WLAN: IV/ICV injection fixed. Fixed: skb was modified prior to sanity check. There is also a workaround against a bug in WSM_A21.05.0288 firmware in this commit. In AP mode FW calculates FCS incorrectly when DA is FF:FF:FF:FF:FF:FF (was seen with TKIP and CCMP security). Workaround checks DA and replaces FF:FF:FF:FF:FF:FF with multicast address 01:00:5E:00:00:16. Workaround is disabled by #if 0 (can be used only for verification, should not be enabled in production). WLAN: Disabling debug printouts (STA/AP). WLAN: Updating u8500_defconfig with CW1200 driver. WLAN: AP mode fine-tuning. + Explicitly set broadcast bit in TIM when broadcasts are available. + Split handling of management frames (link ID = 0) and buffered multicasts (link ID = CW1200_LINK_ID_AFTER_DTIM) Signed-off-by: Dmitry Tarnyagin <dmitry.tarnyagin@stericsson.com>
