* | | ath9k: Advertize beacon_int_infra_matchMohammed Shafi Shajakhan2012-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently ath9k need to have beacon interval matched between STA mode and beaconing mode. Advertize this through interface combinations.

* | | ath9k: Ensure we set FTP_STOMP_LOW weight when WLAN is idleMohammed Shafi Shajakhan2012-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When WLAN is idle ensure we downgrade to FTP_STOMP_LOW weight (from STOMP_LOW) to provide more bandwidth for BT FTP profile. WLAN's idleness can be estimated by taking into account of the rx data packets and just ignore beacons, qos nullfunc etc. Also update bt_wait_time even if the chip is in NETWORK SLEEP mode. This should help BT throughput when WLAN is idle. Signed-off-by: Mohammed Shafi Shajakhan <mohammed@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* | | carl9170: fix spurious transmissions in sniffer modeChristian Lamparter2012-10-29
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several people have complained about an unusual and undocumented feature of the AR9170 hardware: In siffer mode, the hardware generates spurious ACK frames for every received frame... even broadcasts. The reason for this malfunction is unknown: <http://marc.info/?l=linux-wireless&m=134517238506033> But there's a workaround: Instead of the special sniffer mode, the hardware will be put into station mode and all rx filters are disabled.

* | ath9k: perform ANI cycle in idle stateRajkumar Manoharan2012-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As of now the ANI cycle is executed only when the chip is awake. On idle state case, the station wakes up from network sleep for beacon reception. Since most of the time, ANI cycle is not syncing with beacon wakeup, ANI cycle is ignored. Approx 5 mins once, the calibration is performed. This could affect the connection stability when the station is idle for long. Even though the OFDM and CCK phy error rates are too high, ANI is unable to tune its immunity level as quick enough due to rare execution. Here the experiment shows that OFDM and CCK levels are at default even on higher phy error rate. listenTime=44 OFDM:3 errs=121977/s CCK:2 errs=440818/s ofdm_turn=1 This change ensures that ANI calibration will be exectued atleast once for every 10 seconds. The below result shows improvements and immunity levels are adopted quick enough. listenTime=557 OFDM:4 errs=752/s CCK:4 errs=125/s ofdm_turn=0 Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W.

* | carl9170: handle traps from firmware loaderChristian Lamparter2012-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the way the driver deals with command responses and traps which are sent through the special interrupt input endpoint 3. While the carl9170 firmware does not use this endpoint for command responses or traps, the firmware loader on the device does. It uses it to notify the host about 'watchdog triggered' in case the firmware/hardware has crashed. Note: Even without this patch, the driver is still able to detect the mishap and reset the device. But previously it did that because the trap event caused an out-of-order message sequence number error, which also triggered a reset.

This benefits processes that have very many mostly idle sockets, which is quite common. From Eric Dumazet. 10) Use up to 32K for page fragment allocations, with fallbacks to smaller sizes when higher order page allocations fail. Benefits are a) less segments for driver to process b) less calls to page allocator c) less waste of space. From Eric Dumazet. 11) Allow GRO to be used on GRE tunnels, from Eric Dumazet. 12) VXLAN device driver, one way to handle VLAN issues such as the limitation of 4096 VLAN IDs yet still have some level of isolation. From Stephen Hemminger. 13) As usual there is a large boatload of driver changes, with the scale perhaps tilted towards the wireless side this time around. Fix up various fairly trivial conflicts, mostly caused by the user namespace changes. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1012 commits) hyperv: Add buffer for extended info after the RNDIS response message. hyperv: Report actual status in receive completion packet hyperv: Remove extra allocated space for recv_pkt_list elements hyperv: Fix page buffer handling in rndis_filter_send_request() hyperv: Fix the missing return value in rndis_filter_set_packet_filter() hyperv: Fix the max_xfer_size in RNDIS initialization vxlan: put UDP socket in correct namespace vxlan: Depend on CONFIG_INET sfc: Fix the reported priorities of different filter types sfc: Remove EFX_FILTER_FLAG_RX_OVERRIDE_IP sfc: Fix loopback self-test with separate_tx_channels=1 sfc: Fix MCDI structure field lookup sfc: Add parentheses around use of bitfield macro arguments sfc: Fix null function pointer in efx_sriov_channel_type vxlan: virtual extensible lan igmp: export symbol ip_mc_leave_group netlink: add attributes to fdb interface tg3: unconditionally select HWMON support when tg3 is enabled.

The idea is that for WLAN to check if BT owns LNA control and BT is in sleep mode when WLAN just resumes from sleep mode. If the condition is true, do a BTCOEX_RC_WARM_RESET for WLAN to take back the control of shared LNA. Now the issue is the BT sleep value read from MCI register is overlooked by assigning u32 into u8. Hence the above condition never be met so that WLAN used to report beacon losses and frequent connection drops.

This patch fixes the issue by not accessing 'hif_dev' after 'complete(&hif_dev->fw_done)' inside ath9k_hif_usb_firmware_fail(). Cc: ath9k-devel@lists.ath9k.org Cc: "Luis R.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ensure that led pin is filled and set to OFF before starting the driver. With recent changes, drv_start is being called even before led_init is being completed. This is causing led is always OFF on driver load when the interface is UP. This patch splits the led init and fills the led pin before register hw. Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before processing BT profiles or status messages, check whether it is requested to flush BT profile. Otherwise it might increase number of BT profiles that affects the WLAN performance. Also flush the profiles when MCI is recovering from broken rx. After flushing BT profiles, query BT topology to refetch them. Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
