2011-12-19brcm80211: fmac: register a dummy irq handler for SDIO function 2Franky Lin
When there is data available in dongle for driver to fetch, an interrupt will be triggered and both SDIO function 1 and 2 will be flagged by default in bcm4329. These two interrupt flags are identical and only need to be handled once. Since there is no way to turn off one flag from the dongle side, a dummy handler for function 2 interrupt is placed.

2011-12-19b43: avoid packet losses in the dma worker code.francesco.gringoli@ing.unibs.it
Following Rafal request, we verified that on "modern" CPUs using one or more workers is equivalent. Here is patch V3 that addresses the packet loss bug in the dma engine using only one worker. ------- This patch addresses a bug in the dma worker code that keeps draining packets even when the hardware queues are full. In such cases packets can not be passed down to the device and are erroneusly dropped by the code. This problem was already discussed here http://www.mail-archive.com/b43-dev@lists.infradead.org/msg01413.html and acknowledged by Michael. Number of hardware queues is now defined in b43.h (B43_QOS_QUEUE_NUM).

2011-12-16iwlwifi: we can wake SW queues even when draining HW queuesEmmanuel Grumbach
In the very first implementation of HT, the driver was responsible for the queueing: stopping and waking the queues while the HW queues where being drained. In this implementation, we had to deal with the case where we were draining the AGG queue because we wanted to tear down the BA agreement. In the normal flow (when we don't drain any HW queue), when packets are reclaimed, we wake the SW queue in case the SW queue was stopped which can happen when the HW queues are too full. While draining a HW queue, we must make sure that we don't wake the SW queue, since the whole point of the draining is to empty totally the HW queue and not only get below a certain threshold. This is why there is condition in the reclaim function: if (NOT EMPTYING DELBA) wake the SW queue is applicable Since then, a lot has changed and mac80211 is now able to buffer packets that are being sent to a packet list that will be spliced after the driver has reported it has drained its HW queues. Hence, there is no need for the for aforementioned if, and we can safely wake up the queue even if we are draining HW queues. Removing this if, also allows us to remove the wake_queue in check_empty that was there in order to deal with a corner case created by the if.

2011-12-16iwlwifi: don't count the tfds in HW queue any moreEmmanuel Grumbach
Since packets sent to an RA / TID in AGG are sent from a separate HW Tx queue, we may get into a race: the regular queue isn't empty while we already begin to send packets from the AGG queue. This would result in sending packets out of order. In order to cope with this, mac80211 waits until the driver reports that the legacy queue is drained before it can send packets to the AGG queue. During that time, mac80211 buffers packets for the driver. These packets will be sent in order after the driver reports it is ready. The way this was implemented in the driver is as follows: We held a counter that monitors the number of packets for an RA / TID in the HW queues. When this counter reached 0, we knew that the HW queues were drained and we reported to mac80211 that were ready to proceed. This patch changes the implementation described above. We now remember what is the wifi sequence number of the first packet that will be sent in the AGG queue (lets' call it ssn). When we reclaim the packet before ssn, we know that the queue is drained, and we are ready to proceed. This will allow us to move this logic in the upper layer and eventually remove the tid_data from the shared area.
