on sdio remove the bus_if should be configured for close, so new data from higher layers will be blocked. Also the access to bus_if in the watchdog should be checked for null pointer access on sdio remove. Reviewed-by:

when brcmf_sdbrcm_probe_attach results in error then cleanup will result in null pointer access. In brcmf_sdbrcm_release and in brcmf_ops_sdio_remove. This patch fixes order of init and de-init. Reviewed-by:

In brcmf_sdbrcm_probe only error ELINK is seen as error. However brcmf_bus_start can return many more error codes and all should result in failed init of driver. Reviewed-by:

The IF event need special care. It can be either an ADD, DEL, or CHANGE. For an ADD we need to call brcmf_add_if() before the event handler call. Upon a DEL we need to call brcmf_del_if() after the event handler call. CHANGE does not require special attention. Reviewed-by:

The function brcmf_add_if() is called with mac address set to NULL for the primary interface. When handling IF ADD events the firmware provides a address mask in the event to derive its mac address from the primary mac address. Rename the parameter and use it as a mask. Reviewed-by:

Testing revealed the IF ADD event contains the interface index of the new interface. This would result in a NULL pointer access when handling the event. Reviewed-by:

virtual netdevice interface like P2P client and GO need different callbacks for .open and .down. This patch adds those. Reviewed-by:

The brcmf_add_if() function had a struct device as parameter to accomodate the bus specific code to use this function. The driver has been reworked so the bus specific code does not need this function. Better replace the parameter with a more specific driver object, ie. struct brcmf_pub. Reviewed-by:

Handling of firmware event has been reworked into a seperate code file. The change is needed as firmware event can be received in interrupt context. Decoupling of the event handling has been lowered to allow event processing to sleep. Reviewed-by:

An issue is reported in AR9462 & AR9565 that NF_cal_not_done is not observed when HW peak detector calibration is disabled. At that state, the HW is stuck at NF calibration which prevents tx output. The root cause is wrong peak detector offset calibrated by HW. To resolve this issue, peak detector calibration is done manually by SW for AR9462 and AR9565. Signed-off-by:

The firmware supports 8 macid's corresponding to 8 BSS that can be created in an MBSS environment. Currently, BASTREAM commands were always sent with macid 0. This macid is used to configure the hardware ampdu registers with appropriate BSS address in an MBSS environment. This mac address is used by the hardware for various ampdu related requirements e.g. source address in BAR generation, BA interpretation e.t.c. Using invalid macid results in this mac address not getting appropriately configured in the hardware which results in issues during ampdu traffic. Fix this by sending the BASTREAM commands with appropriate macid. Signed-off-by:

Set tx packet timestamp to 0 in following scenarios:- - All packets in STA mode - Mgmt packets in AP mode - Eapol packets in AP mode In STA mode, this field is unused in the firmware. In AP mode, we should not be expiring mgmt and eapol frames. Setting timestamp to 0 will ensure that. Signed-off-by:

ksdioirqd has higher priority than kworker. Process RX packets in SDIO IRQ thread (ksdioirqd/mmcX) directly instead of deferring the work to kworker to avoid the extra latency. This improves TCP throughput 15~20% on an ARM platform with SDIO 2.0 controller. Signed-off-by:
