This patch add support for usb multi endpoints resync. Once multi channel event is received from firmware, update usb_mc_setp flag to block TX data until setup is over. And available data endpoint will be attached to BSS interface. Signed-off-by:

This patch fix missing tx data_sent flag update for usb interface. Except USB interface, data_sent flag has been updated in specific file such as sdio.c and pcie.c. So only USB interface type need check when TX data completed. Signed-off-by:

We have preallocated buffer pool for Tx data. During high data traffic, all buffers are submitted to USB and driver needs to wait until one of the buffers get available for next Tx packet. "data: -ENOSR is returned" errors is expected in this case. Let's lower the priority of this message. Signed-off-by:

Preallocated PCIe buffer is being reused for all PCIe interface events. Physical address of the buffer is shared with firmware so that it can perform DMA on it. As event length is specified in the header, there should not be a problem if the buffer gets overwritten. We will save some cycles by avoiding memset everytime while submitting the buffer to firmware. Fixes: 2728cecd(mwifiex: corrections in PCIe event skb) Signed-off-by:

This NULL pointer dereference is observed during suspend resume stress test. All pending commands are cancelled when system goes into suspend state. There a corner case in which host may receive response for last scan command after this and try to trigger extra active scan for hidden SSIDs. The issue is fixed by adding a NULL check to skip that extra scan. Fixes: 2375fa2b (mwifiex: fix unable to connect hidden SSID..) Cc: <stable@vger.kernel.org> [v4.2+] Signed-off-by:

64k Tx and Rx buffers are allocated during driver initialization for SDIO level data aggregations. When host is under memory pressure situation, kzalloc() request for 64k may fail. We will try allocating 32k buffers and disable our rx single port aggreagation feature in this situation. If the allocation still fails, we will disable our sdio multport aggregation feature as well. In this way, we will transmit and receive packets one by one, thus reduce the demand for big memory. Signed-off-by:

When PCIE type devices are being FW reloaded without being properly reset then the device ends up in a locked state, requiring the device to be completely powered down. This patch adds a reset through watchdog at the moment the device (cores) has been recognized. This will solve warm reboot issues. Cc: Rafal Milecki <zajec5@gmail.com> Reviewed-by:

In case of error during brcmf_bus_start() the network interfaces were freed using free_netdev(). However, the interfaces may have additional memory allocated which is not freed. The netdev has destructor set to brcmf_cfg80211_free_netdev() which frees the additional memory if allocated and call free_netdev(). The brcmf_net_detach() either calls brcmf_cfg80211_free_netdev() directly or uses unregister_netdev() when struct net_device::reg_state indicates the netdev was registered. Reported-by:

Both PCIe and SDIO devices have the possibility to log the firmware console output in kernel log. For PCIe it is logged when PCIE debug level is enabled. For SDIO it is logged when user specifies a non-zero console interval through debugfs. This patch tries to make it a bit more consistent. The firmware console output is only logged when FWCON debug level is enabled. Reviewed-by:

Because the P2P Device interface in firmware uses the same interface index as the primary interface we use the bsscfg index as index in the struct brcmf_pub::iflist. However, in the data path we get the interface index and not the bsscfg index. So we need a mapping of interface index to bsscfg index, which can be determined upon handle adding the interface.
