rt2x00: Add WCID to HT TX descriptor

2011-09-14T17:56:56+00:00

When sending an unencrypted frame to a STA the driver might want to pass
a suitable WCID since we don't have a key index to allow tx status
reports to get properly assigned to the correct STA.

rt2x00: Serialize TX operations on a queue.

2011-07-07T17:20:57+00:00

The rt2x00 driver gets frequent occurrences of the following error message
when operating under load:
phy0 -> rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the
non-full queue 2.

This is caused by simultaneous attempts from mac80211 to send a frame via
rt2x00, which are not properly serialized inside rt2x00queue_write_tx_frame,
causing the second frame to fail sending with the above mentioned error
message.

Fix this by introducing a per-queue spinlock to serialize the TX operations
on that queue.

rt2x00: fix queue timeout checks

2011-04-19T19:39:30+00:00

Add a timestamp to each queue entry which is updated whenever
the status of the entry changes, and remove the per-queue
timestamps.  The previous check was incorrect and caused both
false positives and false negatives.

With the corrected check it comes apparent that the TX status
usually times out on rt2800usb unless there is sufficient traffic
(i.e. the next TX will complete the previous TX status).

rt2x00: Make rt2x00_queue_entry_for_each more flexible

2011-04-19T19:39:13+00:00

Allow passing a void pointer to rt2x00_queue_entry_for_each which in
turn in provided to the callback function.

Furthermore, allow the callback function to stop processing by returning
true. And also notify the caller of rt2x00_queue_entry_for_each if the
loop was canceled by the callback.

No functional changes, just preparation for an upcoming patch.

rt2x00: Fix tx aggregation problems with some clients

2011-04-04T20:20:04+00:00

Some clients seem to rely upon the reception of BlockAckReqs to flush
their rx reorder buffer. In order to fix aggregation for these clients
rt2x00 should send a BlockAckReq if the transmission of an AMPDU
subframe fails.

Introduce a new flag TXDONE_AMPDU to indicate that this is an AMPDU
subframe and pass IEEE80211_TX_STAT_AMPDU_NO_BACK to mac80211 if an
AMPDU subframe failed during transmission.

This fixes aggregation problems with Intel 5100 Windows STAs (and maybe
others as well).
