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).

rt2x00: Use an enum instead of u16 for the rate_mode TX descriptor field

2011-03-04T19:06:48+00:00

This makes the code less error-prone.

rt2x00: Move TX descriptor field "ifs" into plcp substruct

2011-03-04T19:06:47+00:00

"ifs" is only used by no-HT devices. Move it into the plcp substruct and
fill in the value only for no-HT devices.

rt2x00: Optimize TX descriptor memory layout

2011-03-04T19:06:47+00:00

Some fields only need to be u8 and for ifs and txop we can use the
already available enums.

rt2x00: Optimize TX descriptor handling

2011-03-04T19:06:47+00:00

HT and no-HT rt2x00 devices use a partly different TX descriptor.
Optimize the tx desciptor memory layout by putting the PLCP and HT
substructs into a union and introduce a new driver flag to decide which
TX desciptor format is used by the device.

This saves us the expensive PLCP calculation fOr HT devices and the HT
descriptor setup on no-HT devices.
