2012-10-24ath6kl: refactor wmi scan commandKalle Valo
ATH6KL_FW_CAPABILITY_STA_P2PDEV_DUPLEX was checked in cfg80211.c which is a bit awkward when adding more callsites to the scan functions. Refactor the code to wmi.c so that it's transparent to the callers. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2012-10-24ath6kl: move ath6kl_wmi_startscan_cmd()Kalle Valo

2012-07-09cfg80211: use wdev in mgmt-tx/ROC APIsJohannes Berg
The management frame and remain-on-channel APIs will be needed in the P2P device abstraction, so move them over to the new wdev-based APIs. Userspace can still use both the interface index and wdev identifier for them so it's backward compatible, but for the P2P Device wdev it will be able to use the wdev identifier only.

2012-05-11ath6kl: Use correct max-scan-SSIDs limitJouni Malinen
The currently used firmware images support 16 SSIDs in the scan request (indexes 0..15), so update the host driver to use the same limit to allow some more SSIDs to be scanned per request. In addition, change the max-index to max-SSIDs to make it easier to understand the implementation and fix couple of off-by-one checks that could limit the maximum number of entries too strictly.

2012-05-04ath6kl_sdio: Fix the EAPOL out of order issueVivek Natarajan
Send the EAPOL and management frames in the same AC_VO queue. The issue happens when the AP supports QOS, the management frames are sent to AC_VO queue and EAP frame goes to AC_BE queue. Even though the EAP frame is queued before the DEAUTH management frame, as they are queued on different h/w queues, order of delivery between these frames cannot be controlled. This fixes the connection failure seen in P2P case. Signed-off-by: Vivek Natarajan <nataraja@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2012-04-25ath6kl: check for sband existence when creating scan cmdThomas Pedersen
The patch "ath6kl: support fw reporting phy capabilities" gave the firmware the ability to disable certain wiphy supported bands.

2012-04-09ath6kl: Fix 4-way handshake failure in AP and P2P GO modeVasanthakumar Thiagarajan
RSN capability field of RSN IE which is generated (which is what really advertised in beacon/probe response) differs from the one generated in wpa_supplicant. This inconsistency in rsn IE results in 4-way handshake failure. To fix this, configure rsn capability used in wpa_supplicant in firmware using a new wmi command, WMI_SET_IE_CMDID.

2012-01-30ath6kl: Wait for host sleep mode cmd processed event during WOW suspendRaja Mani
For every WMI_SET_HOST_SLEEP_MODE_CMDID command (send from the host), the firmware sends WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENTID as an acknowledgement to the host. In order to being sync with the firmware, the host has to wait for WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENT event before going to the suspend state. This patch ensures ath6kl_wow_suspend() waits until it gets this event after sending set host sleep mode command. This patch adds, * New command WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENTID in WMI event table. * New WMI function ath6kl_wmi_host_sleep_mode_cmd_prcd_evt_rx() to process the event. * New flag HOST_SLEEP_MODE_CMD_PROCESSED in VIF flags to record the arrival of the event.

2012-01-30ath6kl: Configure WOW patterns while going to wow_suspendRaja Mani
First preference is given to the user configured WOW patterns. If the user doesn't configure any patterns (for ex, via iw command), the default patterns will be configured based on the current mode (vif->nw_type) while going to WOW suspend. Summary of changes: * ath6kl_wow_ap() is added to configure the below default patterns when the system enters into WOW suspend in AP mode. + Unicast IP, EAPOL-like and ARP packet pattern + ARP packet pattern + mDNS/SSDP/LLMNR pattern + DHCP broadcast pattern * ath6kl_wow_sta() is added to configure the below default patterns when the system enters into WOW suspend in STA mode. + Unicast packet pattern + mDNS/SSDP/LLMNR pattern * Move the user provided WOW patterns configuration code from ath6kl_wow_suspend() to a separate function called ath6kl_wow_usr(). * Two argument variable's ('filter' and 'mask) data type in ath6kl_wmi_add_wow_pattern_cmd() are changed from 'u8 *' to 'const u8 *'. This is needed to make all pattern and mask arrays to be 'static const u8' in the caller function. * New conditional check is added to make sure user configured pattern count is within the limit (WOW_MAX_FILTERS_PER_LIST).

2012-01-18ath6kl: get rid of AR_DBG_LVL_CHECK()Kalle Valo
We don't need it as debug calls already have a log level and compiler should be smart enough to optimise away the code when ath6kl debug code is not enabled. Also it makes it easier to abstract core code to ath6kl_core.ko. In ath6kl_dump_registers() I had to change the debug level from ANY to IRQ as I removed the AR_DBG_LVL_CHECK() check before calling the function. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2012-01-13ath6kl: Add support for uAPSDThirumalai Pachamuthu
* A new APSD power save queue is added in the station structure. * When a station has APSD capability and goes to power save, the frame designated to the station will be buffered in APSD queue. * When the host receives a frame which the firmware marked as trigger, host delivers the buffered frame from the APSD power save queue. Number of frames to deliver is decided by MAX SP length. * When a station moves from sleep to awake state, all frames buffered in APSD power save queue are sent to the firmware. * When a station is disconnected, all frames bufferes in APSD power save queue are dropped. * When the host queues the first frame to the APSD queue or removes the last frame from the APSD queue, it is indicated to the firmware using WMI_AP_APSD_BUFFERED_TRAFFIC_CMD. kvalo: fix buggy handling of sks queues, made it more obvious the user priority when wmm is disabled, remove unneed else block and combined some variable declarations Signed-off-by: Thirumalai Pachamuthu <tpachamu@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2011-12-14ath6kl: support for P2P mgmt operations on station interfaceAarthi Thiruvengadam
This patch enables support for doing P2P management operations like device discovery on top of a station interface. After group formation, the station interface will become a P2P GO/client interface as the case may be. This feature requires modifications to a couple of existing WMI structures and therefore new command ids and structures have been defined in order to be compatible with older firmware versions and other chips. The exception here is the wmi_connect_cmd. Adding a new field to the end of the structure will not cause any issues with previous firmware versions since firmware only checks for minimum length of the command. The other structures are of variable length, hence it was not possible to add new fields to the end. The new command ids have to be added to the end of enum wmi_cmd_id, so it has updated to match the firmware. The driver will support both the 'old' and the 'new' commands for a while by checking the firmware capabilities.

2011-12-13ath6kl: implement scheduled scanKalle Valo
ath6kl firmware supports scheduled scan functionality with the wow ssid filter.

2011-11-13ath6kl: Fix target minimum length requirement for WMI_SEND_PROBE_RESPONSE_CMDIDAarthi Thiruvengadam
The firmware expects the minimum length of WMI_SEND_PROBE_RESPONSE_CMDID to be 13. However, when the device is a P2P GO and it needs to send a probe response to a non-P2P client, there are no P2P IEs to be added, and therefore the length of the WMI command is 12. This command gets rejected by the firmware. To fix this, add an extra byte to satisfy the minimum length requirement.

Even though only a single concurrent remain-on-channel operation is supported, there may be two pending remain-on-channel events (one to indicate end of a canceled operation and another to indicate start of a new operation). User space won't be able to distinguish these events unless unique cookies are used. The previous behavior resulted in wpa_supplicant getting quite confused about the driver's offchannel state in various sequences and this made the P2P state machine behave incorrectly.
