2012-02-06ath9k: cleanup a min_t() castDan Carpenter1-1/+1

2012-01-30ath6kl: Wait for host sleep mode cmd processed event during WOW suspendRaja Mani4-0/+35
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 Mani3-44/+193
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).

2012-01-30ath6kl: Re-architect suspend mode handling in ath6kl_sdio_suspendRaja Mani3-38/+64
Using this patch, the user can bypass existing auto suspend mode selection logic and force ath6kl to enter into the suspend mode what he/she wants. If the user doesn't choose any suspend mode while doing insmod of the driver, auto suspend mode selection logic will kick in and choose suspend mode based on the host SDIO controller capability. Generic module parameter is required to specify suspend mode including Deep Sleep and WOW while doing insmod. Renaming existing mod param variable suspend_cutpower would be sufficient to meet this requirement. New module parameter suspend_mode can take any one of the below suspend state, 1. cut power 2. deep sleep 3. wow Signed-off-by: Raja Mani <rmani@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2012-01-30ath6kl: Fix kernel panic during rx aggregationVasanthakumar Thiagarajan3-5/+7
"ath6kl: Define a structure for connection specific aggregation information" introduces this. In aggr_conn_init(), vif->aggr_cntxt is assigned to aggr_conn->aggr_info, but vif->aggr_cntxt is not initialized at this point, this would end up accessing an invalid pointer in aggregation receive path. Fix this by passing the correct aggr_info to aggr_conn_init(). The panic trace would look like.

2012-01-18ath6kl: add back beginnings of USB supportKalle Valo8-8/+479
John Linville had to revert the part of USB support which was already in ath6kl due to build problems in commit cb00ec382b ("ath6kl: revert USB support"). Now that I fixed the build problems properly by adding ath6kl_core.ko kernel module it's possible to add back the (incomplete) USB support. This patch is a revert of John's patch and adds back the USB code which as already in ath6kl, only difference being minor changes in Makefile and adapting usb.c to new core function names. Note that USB support in ath6kl is not complete yet. This code only makes it possible to boot firmware but as HTC layer does not yet support USB it's not possible to send any WMI commands nor data packets to the firmware. That will be added soon.

Documentation states that the KeyMiss flag is only valid if RxFrameOK is unset, however empirical evidence has shown that this is false. When KeyMiss is set (and RxFrameOK is 1), the hardware passes a valid frame which has not been decrypted. The driver then falsely marks the frame as decrypted, and when using CCMP this corrupts the rx CCMP PN, leading to connection hangs.

2012-01-12ath6kl: Fix listen interval handlingSujith Manoharan4-33/+24
This patch addresses a few problems with the commit: "ath6kl: Implement support for listen interval from userspace" * The debugfs file required for reading/writing the listen interval wasn't created. Fix this. * The interface index was being hardcoded to zero. Fix this. * Two separate parameters, "listen_interval_time and listen_interval_beacons" were being used. This fails to work as expected because the FW assigns higher precedence to "listen_interval_beacons" and "listen_interval_time" ends up being never used at all. To handle this, fix the host driver to exclusively use listen interval based on units of beacon intervals.

2012-01-12ath6kl: Fix SDIO error pathSujith Manoharan1-1/+0
sdio_release_host() would be called twice if sdio_set_block_size() fails for some reason, which would result in the following warning.

2012-01-11ath9k: Fix regression in channelwidth switch at the same channelRajkumar Manoharan2-6/+3
The commit "ath9k: Fix invalid noisefloor reading due to channel update" preserves the current channel noisefloor readings before updating channel type at the same channel index. It is also updating the curchan pointer. As survey updation is also referring curchan pointer to fetch the appropriate index, which might leads to invalid memory access. This patch partially reverts the change and stores the noise floor history buffer before updating channel type w/o updating curchan.
