2012-03-07ath6kl: Set optimal listen intvl,bmiss,scan params while going to wow suspendRaja Mani
* In order to save the target power in WOW suspend state, configure the best optimal values for the below parameters, - listen interval. - beacon miss interval. - scan parameters. Default values for above attributes are reverted in wow resume operation. * The default listen interval is set before the host issue connect request. * New function is added to configure beacon miss count. kvalo: minor changes to fix open parenthesis alignment Signed-off-by: Raja Mani <rmani@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2012-02-27ath6kl: Add unicast mgmt frame bufferingNaveen Gangadharan
PS buffering of unicast Action frames that are sent in a context of a BSS. In AP mode when the recepient station goes to powersave and PS_POLL flag is not set, we would buffer the frames. Send out unicast mgmt bufferred frame when PS_POLL is received.

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).

2012-01-13ath6kl: 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>

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: Avoid taking struct as argument in ath6kl_wmi_set_ip_cmdRaja Mani
In this way, caller is free to pass only the value of IP addr to configure. In addition to this, * 'ips' variable data type in struct wmi_set_ip_cmd is changed from __le32 to __be32 in order to match network byte order. * ipv4_is_multicast() is used to validate multicast ip addr. * New argument if_idx is added to supply correct vif index to ath6kl_wmi_cmd_send().

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. 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>

2011-11-11ath6kl: add aborted parameter to ath6kl_cfg80211_scan_complete_event()Kalle Valo
Currently it takes an error code as status, but what we really want to tell is if the scan was aborted or not. Also fix a bug where we were comparing firmware scan status values with kernel error codes, which is obviously wrong. This meant that ath6kl didn't detect when firmware informed about failed scans. I doubt that this fix doesn't make any difference in practise but it still needs to be fixed. This is fixed by adding an enum for the success status code and checking for that.

2011-09-22ath6kl: Remove unnecessary bssinfo event header conversionJouni Malinen
There is no point in unconditionally converting the bssinfo header to the old version since only the new header is being used and the driver can as well read the values from it when needed. Leaving out the conversion saves some extra memory copying. In addition, use the calculated "rssi" value snr - 95 dBm to get the proper value in cfg80211 BSS table (i.e., something that more or less matches with the value used in STA info).

2011-09-06ath6kl: Fix AP mode connect event parsing and TIM updatesJouni Malinen
This cleans up the connect event parsing by defining a union in struct wmi_connect_event to match with the three possible sets of fields that the target uses depending on which type of connect event is being indicated. In addition, two AP cases are now separated from ath6kl_connect_event() so that correct field names can be used to make it actually possible to understand what the code is doing. The bug hiding in the previous mess was in parsing the AID incorrectly when processing the new station connecting event in AP mode.
