Today all the interface drivers (usb/pcie/sdio) assign the adapter->dev in the register_dev() callback, although they have this piece of info well before hand. This patch makes the device structure available for mwifiex right at the beginning, so that it can be used for early initialization if needed. This is needed for subsequent patches in this patchset that intend to unify and consolidate some of the code that would otherwise have to be duplicated among the interface drivers (sdio, pcie, usb).

If adapter is null the error exit path in mwifiex_shutdown_sw is to down the semaphore sem and print some debug via mwifiex_dbg. However, passing a NULL adapter to mwifiex_dbg causes a null pointer deference when accessing adapter->dev. This fix checks for a null adapter at the start of the function and to exit without the need to up the semaphore and we also skip the debug to avoid the null pointer dereference.

This patch implements pre and post FLR handlers to support PCIe FLR functionality. Software cleanup is performed in pre-FLR whereas firmware is downloaded and software is re-initialised in post-FLR handler. Following command triggers FLR. echo "1" > /sys/bus/pci/devices/$NUMBER/reset This feature can be used as a recovery mechanism when firmware gets hang.

Beacon report radio measurement requires reporting observed BSSs on the channels specified in the beacon request. If the measurement mode is set to passive or active, it requires actually performing a scan (passive or active, accordingly), and reporting the time that the scan was started and the time each beacon/probe was received (both in terms of TSF of the BSS of the requesting AP). If the request mode is table, this information is optional. In addition, the radio measurement request specifies the channel dwell time for the measurement. In order to use scan for beacon report when the mode is active or passive, add a parameter to scan request that specifies the channel dwell time, and add scan start time and beacon received time to scan results information. Supporting beacon report is required for Multi Band Operation (MBO).

Calling sdio_claim_host() from the interface independent part of the mwifiex driver is not only a layering violation, but also causes a link error if MMC support is disabled, or if CONFIG_MMC=m and CONFIG_MWIFIEX=y: drivers/net/built-in.o: In function `mwifiex_fw_dpc': :(.text+0xff138): undefined reference to `sdio_claim_host' :(.text+0xff158): undefined reference to `sdio_release_host' The right way to do this is to have the sdio specific code in the sdio driver front-end, and we already have a callback pointer that we can use for this after exporting the generic fw download function from the core driver.

The action 'check for winner' and 'download firmware' should be an atomic action. This is true for btmrvl driver but not mwmfiex, which cause firmware download to fail when the following senerio happens: 1) mwifiex check winner status: true 2) btmrvl check winner status: true, and start downloading firmware 3) mwfieix tries to download firmware, but failed because btmrvl is already downloading. This won't happen if 1) and 3) is an atomic action. This patch adds sdio_claim/release_host call around those two actions to make sure it's atomic.

Host hang is observed if card is removed before firmware download gets completed. In this case, firmware will be failed to download and adapter structure gets freed. In other thread, mwifiex_remove_card() waits on semaphore until the firmware download fails. This wait is not necessary and may result in invalid adapter access.

When hostapd/ wpa_supplicant asks for ack status of an EAPOL/ACTION frame, driver maintains a cloned skb for the packet until TX_STATUS event is received from firmware.

This will expose in /sys whether the ifname of a device is set by userspace or generated by the kernel. The latter kind (wlanX, etc) is not deterministic, so userspace needs to rename these devices to names that are guaranteed to stay the same between reboots. The former, however should never be renamed, so userspace needs to be able to reliably tell the difference.

This patch brings in support for SDIO single port rx aggregation to mwifiex. Maximum read size support by SDIO cmd53 is 64K. Based on multi port aggregation which is already part of mwifiex, idea here is multiple packets received in FW can be aggregated into single buffer. A separate upload type is defined for such packet aggregated to single port. Packets from this single buffer are later deaggregated into individual packets. This way, driver can receive more packets each time through single SDIO cmd53; thereby reducing no of times MMC bus is accessed. SDIO SP aggregation support is advertised by FW during load time and driver would get FW block size in command response of HostCmd_CMD_SDIO_SP_RX_AGGR_CFG.

This patch handles a corner case where TX packet would remain in driver queue till next packet comes in. Here is sequence: 1. TX packet is queued via hard_start_xmit and main_work is queued 2. SDIO interrupt comes in which directly call mwifiex_main_process. This starts executing main superloop. 3. Now work from step1 is scheduled but at first check itself it sees mwifiex_processing is set and exits. 4. Now if superloop from step2 has passed TX processing part of superloop this packet would remain in queue until next packet/command/SDIO interrupt arrives and queues main_work. This patch fixes this corner case by defining more_task flag which is set when mwifiex_processing is found to be true. At end of superloop we again check if more_task flag is set and if set, execute superloop again.
