Since the addition of the TXQ stats to cfg80211, the station_info struct has grown to be quite large, which results in warnings when allocated on the stack. Fix the affected places to do dynamic allocations instead. Fixes: 52539ca8 ("cfg80211: Expose TXQ stats and parameters to userspace") Reviewed-by:

While carrying energy detection(ED) tests, the chip will stop transmission upon detecting an energy in the connected channel. As a feedback, driver will stop dequeuing TX packets and due to which wmm_tx_pending keep incremeting. Once wmm_tx_pending reaches 100, driver calls netif_tx_stop_queue(). If TX ques is not restarted within 5(watchdog_timeo) seconds, it will result in TX timeout. The ED test is carried out for one minute and the current threshold of 100 is easily overcome by the traffic, cuasing TX timeouts. To fix this increase the threshold to 400. Signed-off-by:

Add support for the BCM43364 chipset via an SDIO interface, as used in e.g. the Murata 1FX module. The BCM43364 uses the same firmware as the BCM43430 (which is already included), the only difference is the omission of Bluetooth. However, the SDIO_ID for the BCM43364 is 02D0:A9A4, giving it a MODALIAS of sdio:c00v02D0dA9A4, which doesn't get recognised and hence doesn't load the brcmfmac module. Adding the 'A9A4' ID in the appropriate place triggers the brcmfmac driver to load, and then correctly use the firmware file 'brcmfmac43430-sdio.bin'. Signed-off-by:

We have check if queue is not empty when start flushing queues on by mac80211 callback, but we also can start flushing queues by internal driver calls. So move check into rt2x00queue_flush_queue() to assure we do not flush empty queue anytime. Additionally add warning if we start to kick empty queue as in such situation we set wrong index in the HW queue, what can confuse the HW and have various negative consequences. Signed-off-by:

Revision 7 of PCIe dongle interface increases the item size of tx and rx complete rings to accommodate extra payload for new feature. This patch simply bump up the size of these two rings without adding the support for utilizing the new space. This makes brcmfmac compatible with rev7 firmware. Reviewed-by:

pm_runtime handles sdio power on and power off transitions. An old workaround for trying to control the power explicitly from the driver was in fact causing failures on suspend/resume as the mmc layer already power the module on resume. In case of resume pm_runtime_get sync returns a positive device's usage count causing the driver to try an re-initialize an already initialized device. This was causing sdio bus failure on resume. Remove this manual power on/off sequence as it is in-fact not needed. Signed-off-by:

dma_tx_fragment() is never called in atomic context. dma_tx_fragment() is only called by b43legacy_dma_tx(), which is only called by b43legacy_tx_work(). b43legacy_tx_work() is only set a parameter of INIT_WORK() in b43legacy_wireless_init(). Despite never getting called from atomic context, dma_tx_fragment() calls alloc_skb() with GFP_ATOMIC, which does not sleep for allocation. GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL, which can sleep and improve the possibility of sucessful allocation. This is found by a static analysis tool named DCNS written by myself. And I also manually check it. Signed-off-by:

In case of "any" wowlan trigger is configured, no valid wakeup filter was configured. Moreover, the fw assumes there's no connection when there are no configured wakeup filters. This leads to the station info not being updated on D3 command, causing rate_n_flags to be 0 when the offloading code sends tx frame (triggering SYSASSERT_102C due to invalid antenna param) Note: "any" trigger is currently assumed to only be used when entering d0i3 (which has a different flow). However, we still reach this code when using d3_test. Signed-off-by:

The bitfield we use in struct iwl_cfg contains 17 bits, but we declare it as u16. The compiler doesn't seem to have any problems with that (it probably automatically makes it u32), but it's cleaner to use a type that is long enough for all the flags. Signed-off-by: -

If we fail to to grab NIC access because the device is not responding (i.e. CSR_GP_CNTRL returns 0xFFFFFFFF), remove the device from the PCI bus, to avoid any further damage, and to let the user space rescan. In order to inform the userspace that a rescan is needed, we send a kobject uevent with "INACCESSIBLE". This functionality is disabled by default, but can be enabled via a new module parameter called "remove_when_gone". In the future we may change this module parameter to include 3 modes instead: do nothing; auto-rescan or; send uevent. Signed-off-by:
