rt2x00: change beaconing setup on RT2800

2014-06-19T19:49:15+00:00

As reported by Matthias, on 5572 chip, even if we clear up TXWI
of corresponding beacon, hardware still try to send it or do other
action that increase power consumption peak up to 1A.

To avoid the issue, setup beaconing dynamically by configuring offsets
of currently active beacons and MAC_BSSID_DW1_BSS_BCN_NUM variable,
which limit number of beacons that hardware will try to send.

rt2x00: Fix FSF address in file headers

2013-12-11T15:56:19+00:00

Several files refer to an old address for the Free Software Foundation
in the file header comment.  Resolve by replacing the address with
the URL  so that we do not have to keep
updating the header comments anytime the address changes.

rt2x00: remove data_queue_desc struct

2013-06-12T18:59:38+00:00

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.

rt2x00: rt2x00queue: add priv_size field to struct data_queue

2013-06-12T18:59:33+00:00

Add a new field into struct data_queue and store
the size of the per-queue_entry private data in
that. Additionally, use the new field in the
rt2x00queue_alloc_entries function to compute
the size of the queue entries for a given queue.

The patch does not change the current behaviour
but makes it possible to remove the queue_desc
parameter of the rt2x00queue_alloc_entries function.
That will be done by a subsequent patch.

rt2x00: provide separate information about TXWI & RXWI sizes

2013-04-22T19:20:20+00:00

On new 2800 hardware sizes of TXWI & RXIW can be different than TXD
& RXD sizes, so we need to difference between them. Let's define
winfo_size as size of in buffer descriptor (TXWI & RXWI), and desc_size
of as size of additional descriptor - in separate DMA coherent buffer
for PCI hardware (TXD & RXD) and yet another in buffer descriptor for
USB hardware (TXINFO & RXINFO).

Change is rt2x00 wild, but should affect only 2800 driver.

Patch also fix beaconing for 5592usb AP mode.

rt2x00: Fix tx status reporting for reordered frames in rt2800pci

2013-03-18T20:38:29+00:00

rt2800 hardware sometimes reorders tx frames when transmitting to
multiple BA enabled STAs concurrently.

For example a tx queue
	[ STA1 | STA2 | STA1 | STA2 ]
can result in the tx status reports
	[ STA1 | STA1 | STA2 | STA2 ]
when the hw decides to put the frames for STA1 in one AMPDU.

To mitigate this effect associate the currently processed tx status
to the first frame in the tx queue with a matching wcid.

This patch fixes several problems related to incorrect tx status
reporting. Furthermore the tx rate selection is much more stable when
communicating with multiple STAs.

rt2x00: Revert "rt2x00: remove unused argument"

2013-03-18T20:38:29+00:00

This reverts commit db36f792370959ff26458f80942cf98fe8249d95
since I'm going to use the data pointer that was removed in
a follow up patch.

rt2x00: rt2800usb: rework txstatus code

2012-03-15T17:40:31+00:00

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.
