Below changes are done: * Device 80MHz clock should be disabled for 9116 in 20MHz band. * Default edca parameters should be used initially before connection. * Default TA aggregation is 3 for 9116. * Bootup parameters should be loaded first when channel is changed. * 4 byte register writes are possible for 9116.

Initial frame exchange sequence has been changed for 9116 chip. Getting MAC address using EEPROM read frame will be once common device configuration is done and RESET_MAC frame is sending after bootup parameters confirmation is received, which are different from RS9113 device Signed-off-by:

Siva Rebbagondla authored
Till software bootloader ready state, communication with device is common for 9113 and 9116. Hence moved that part of firmware loading to separate function rsi_prepare_fw_load(). Also LMAC_VER_OFFSET is different for 9113 and 9116, so renamed existing macro to LMAC_VER_OFFSET_9113 Signed-off-by:

9116 device id entry is added in both SDIO and USB interfaces. New enumberation value taken for the device model. Based on the device model detected run time, few device specific operations needs to be performed. adding rsi_dev_model to get device type in run time, as we can use same driver for 9113 and 9116 except few firmware load changes.

Sometimes we can get into situation when there are pending statuses, but we do not get INT_SOURCE_CSR_TX_FIFO_STATUS. Handle this situation by arming timeout timer and read statuses (it will fix case when we just do not have irq) and queue work to handle case we missed statues from hardware FIFO. Signed-off-by:

Do not disable txstatus interrupt and add quota of processed tx statuses in one tasklet. Quota is needed to allow to fed device with new frames during processing of tx statuses.

For unknown reasons printk() on some context can cause CPU hung on embedded MT7620 AP/router MIPS platforms. What can result on wifi disconnects. This patch move queue full messages to debug level what is consistent with other mac80211 drivers which drop packet silently if tx queue is full. This make MT7620 OpenWRT routers more stable, what was reported by various users. Signed-off-by:

Some USB host devices/drivers on some conditions can always return EPROTO error on submitted URBs. That can cause infinity loop in the rt2x00 driver. Since we can have single EPROTO errors we can not mark as device as removed to avoid infinity loop. However we can count consecutive EPROTO errors and mark device as removed if get lot of it. I choose number 10 as threshold. Reported-and-tested-by:

Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes, in particular in the context in which this code is being used. So, replace code of the following form: sizeof(*pmkids) + max_pmkids * sizeof(pmkids->bssid_info[0]) with: struct_size(pmkids, bssid_info, num_pmkids) This code was detected with the help of Coccinelle.

In case the the trigger occurrences is zero or force_restart is set, the driver sets IWL_FWRT_STATUS_DUMPING without actually scheduling trigger collection. At this point no other dump collection can be performed. Solve this by setting IWL_FWRT_STATUS_DUMPING bit only when the driver is surely going to schedule dump collection Signed-off-by:

When building with -Wsometimes-uninitialized, Clang warns: drivers/net/wireless/intel/iwlwifi/mvm/sta.c:2114:12: warning: variable 'queue' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] Clang can't evaluate at this point that WARN(1, ...) always returns true because __ret_warn_on is defined as !!(condition), which isn't immediately evaluated as 1.
