2012-03-15rt2x00: rt2800usb: limit tx queues lengthStanislaw Gruszka1-1/+1
TX status fifo is limited to 16 elements. When we send more frames than that, we can easily loose status, what is not good for rate scaling algorithm. On my testing the change does not degrade performance, actually make is slightly better. Additionally with the patch I can see much less various rt2x00 warnings in dmesg.

2012-03-15rt2x00: rt2800usb: do not check packedid for aggregated framesStanislaw Gruszka1-2/+3
Tx statuses of aggregated subframes contain packetid of first subframe in the AMPDU. We can not identify AMPDU subframes based on packedid, so simply assume that status match first pending frame in the queue. Thats mostly the same what 2800pci do.

2012-03-15rt2x00: rt2800usb: rework txstatus codeStanislaw Gruszka5-64/+101
Currently we read tx status register after each urb data transfer. As callback procedure also trigger reading, that causing we have many "threads" of reading status. To prevent that introduce TX_STATUS_READING flags, and check if we are already in process of sequential reading TX_STA_FIFO, before requesting new reads. Change timer to hrtimer, that make TX_STA_FIFO overruns less possible. Use 200 us for initial timeout, and then reschedule in 100 us period, this values probably have to be tuned. Make changes on txdone work. Schedule it from rt2800usb_tx_sta_fifo_read_completed() callback when first valid status show up. Check in callback if tx status timeout happens, and schedule work on that condition too. That make possible to remove tx status timeout from generic watchdog. I moved that to rt2800usb. Loop in txdone work, that should prevent situation when we queue work, which is already processed, and after finish work is not rescheduled again.

2012-03-15rt2x00: rt2800usb: rework txdone codeStanislaw Gruszka1-41/+31
Patch change txdone code to make it similar like txdone in rt2800pci, process only one entry from queue matching tx status. Before we processed all pending entries from queue until PACKEDID match, that caused that we do not report tx statuses correctly.

2012-03-13mac80211: rename bss_conf timestamp to last_tsfJohannes Berg3-3/+3
This value is not really very useful by itself, yet some drivers (including iwlwifi until I can figure out what it should do) use it. At least rename it to "last_tsf" to indicate the meaning and add a note that it may be really old. I suspect the value may become useful combined with the rx_status->mactime, but we don't (yet) store that value and pass it to the driver.

2012-03-13b43: Load firmware from a work queue and not from the probe routineLarry Finger2-27/+35
Recent changes in udev are causing problems for drivers that load firmware from the probe routine. As b43 has such a structure, it must be changed. As this driver loads more than 1 firmware file, changing to the asynchronous routine request_firmware_nowait() would be complicated. In this implementation, the probe routine starts a queue that calls the firmware loading routines. Signed-off-by: Larry Finger <[email protected]> Signed-off-by: John W. Linville <[email protected]>
