When initialization within brcmf_bus_start() fails on steps before the brcmf_net_attach() the net_device for the primary interface needs to be freed. This patch resolves a panic during kernel boot as reported by Stephen Warren. ref.: http://mid.gmane.org/51AD1F22.2080004@wwwdotorg.orgTested-by:

When data is available and fw signalling is enabled then TIM information should be sent to firmware. If it can piggy back on existing packet then do that otherwise create dummy packet to get information out. Cc: Dan Carpenter <dan.carpenter@oracle.com> Reviewed-by:

In brcmf_net_attach() the hard_header_len is set to sum of ETH_HLEN and the headroom needed by the bus interface. Better use increment instead as hard_header_len is already initialized upon alloc_netdev(). Reviewed-by:

The BDC header contains PropTx TLV signals that are useful to capture for debugging. This event captures the header and tlv's in binary form. This can be post-processed using trace-cmd plugin. Reviewed-by:

Currently suppressed packets get enque-ed with header which then gets pulled before transmit. It is more logical and clean to pull the header on return and push it unconditionally on xmit. Reviewed-by:

During P2P testing it turned out that the firmware sents multiple multiple creditmap event messages. Only the first message from the firmware should be processed. Otherwise the firmware-signalled flow control can run haywire when it has packets outstanding in firmware. Reviewed-by:

The destination entries for firmware-signalled flow control have the interface id stored. This needs to be translated to bsscfg index when looking up the ifp object for the interface. Reviewed-by:

In case of TDLS find the correct MAC descriptor for fw signalling data. In case of TDLS each destination gets its own entry. This was not handled correctly for P2P client. Reviewed-by:

When credit borrowing is active the BE credits have been depleted, however the worker should still be scheduled. In case of credit borrowing correct credit map to make sure worker remains active. Reviewed-by:

Currently on a bus flow control both fws is informed and netif queue gets closed. In case of fw signalling enabled, let the flow control be handled by fw signalling only. Reviewed-by:

The debug logging in firmware-signalling code was rather extensive and for a large part in the data path. This patch removes large part or the level is changed to DATA level. Reviewed-by:

Firmware can request the driver for transmit packets using two different signals. Only for one signal a flag was set in the sk_buff control buffer. This patch adds explicit flag for the other signal as well. Reviewed-by:

On bus flow control (no more host bus resources to send packets to device) the netif flow control was toggled, however credit management should also take this status into account. Since there are multiple sources handling this flow control necessary spinlocks were added to protect flow control related data/states. Reviewed-by:

The brcmf_skbuff_cb structure contain if_flags and htod fields. Both have a bitfield defined to hold the fifo number. With a small code change we get rid of the fifo bitfield in if_flags. Reviewed-by:

The firmware-signal API specification defines length for the different tlv. During testing on different devices it turned out not all firmware used the tlv length according specification. Therefore the length check is made less strict with this patch. Reviewed-by:

The extra_tx_headroom field of struct rt2x00_ops indicates the extra TX headroom size required for a given device. This data is redundant, the value can be computed from the desc_size and winfo_size fields of the TX queues. Move the extra_tx_headroom field to struct rt2x00_dev, compute its value in the probe routine and use the cached value in the rest of the code. Signed-off-by:

PATCH "mwifiex: scan delay timer cleanup in unload path" adds code to cancel scan delay timer in unload path. It causes a regression for USB interface. USB8797 card gets enumerated twice. First enumeration is for firmware download and second enumeration expects firmware initialization. It was observed that we are trying del_timer_sync() without setting up the timer when remove handler is called after first enumeration. This patch moves setup_timer() call to appropriate place so that timer is setup for both the enumerations. Signed-off-by:

If the queue_init callback is implemented by a driver it gets used instead of the data_queue_desc based initialization. The queue_init callback is implemented for each drivers now, so the old initialization method is not used anymore. Remove the unused data_queue_desc structure and all of the related code.

The generic rt2x00 code has been changed to allow the drivers toimplement dynamic data_queue initialization. Remove the static data queue descriptor structures and implement the queue_init callback instead. The actual chipset is already known when the callback is used. This allows us to use a single callback for all supported devices. Signed-off-by:

The driver uses static data structures for initializing specific fields of a given data queue. These static queue data descriptor structures are containing values which related to a given chipset. Even though the values are chip specific, the actual selection of the used structure is based on device specific vendor/product identifiers. This approach works, but it is not always reliable. Sometimes the vendor and/or device IDs of the PCI and USB devices contains improper values which makes it impossible to select the correct structure for such devices. The patch adds a new callback to tr2x00_ops which is called after the chipset detection is finished. This allows the drivers to do dynamic initialization of the data_queue structure for a given queue based on the actual chipset. After each driver implements the queue_init callback, the data_queue_desc structure will be removed. Signed-off-by:

Use the queue->limit value instead of the qdesc->entry_num to compute the threshold. The two source values are the same and the data queue descriptor structure will be removed by a later patch. Also separate the computation from the rest of the init code to make further changes easier. Signed-off-by:

The beacon data queue is initialized already, so fetch the number of the queue entries from that instead of using the entry_num field of the data queue descriptor. The two values are the same, and the use of the rt2x00dev->bcn->limit value allows us to get rid of a superfluous pointer dereference. Signed-off-by:
