wl12xx: use kstrtoul_from_user

2011-09-14T08:47:43+00:00

simplify code by calling kstrtoul_from_user() (instead of
copy_from_user() + kstrtoul())

wl12xx: add beacon_filtering debugfs file

2011-09-14T08:47:18+00:00

Allow enabling/disabling beacon_filtering by debugfs,
in order to reduce the log size while debugging (beacon
filtering is disabled by default in AP mode, as beacons
are needed for ERP configuration).

wl12xx: schedule TX packets according to FW packet occupancy

2011-08-22T09:35:30+00:00

When selecting packets for transmission, prefer the ACs that are least
occupied in the FW. When packets for multiple ACs are present in the FW,
it decides which to transmit according to WMM QoS parameters.

With these changes, lower priority ACs should not be starved when higher
priority traffic is present.

wl12xx: update fw status struct

2011-08-22T09:35:23+00:00

Update the fw status struct according to the new fw api
(fw >= 6/7.0.0.35).
All the roles use the same struct now.

The memory accounting was changed a bit according to
the struct changes.

wl12xx: remove rx filtering stuff

2011-08-22T09:35:23+00:00

The new fw doesn't support rx_filtering configuration (as a
stand-alone command. the rx filtering is done automatically
according to the active role).

wl12xx: Revert "wl12xx: schedule TX packets according to FW occupancy"

2011-08-22T09:35:22+00:00

This does not make sense in fw >= 6/7.3.0.0.75 (wl127x/wl128x) -
we don't use Tx blocks to measure FW occupancy anymore.

This reverts commit 9e374a37b6fa2310b71d3c5657cd0c1e693120c6.

wl12xx: start/stop queues according to global per-AC counters

2011-07-08T06:39:47+00:00

Split tx_queue_count to count per-AC skb's queued, instead of relying on
the skb-queue len. The skb queues used were only valid in STA-mode, as
AP-mode uses per-link queues.

This fixes a major regression in AP-mode, caused by the patch
"wl12xx: implement Tx watermarks per AC". With that patch applied, we
effectively had no regulation of Tx queues in AP-mode. Therefore a
sustained high rate of Tx could cause exhaustion of the skb memory pool.

it decides which to transmit according to WMM QoS parameters.

wl12xx: fix Tx security sequence number handling

2011-07-05T18:33:19+00:00

Do not reset the security sequence number when issuing a join command or
interface is removed. Instead, reset the counter only during the unjoin
command.

Added the notion of counter wrap-around to the LSB number in
wl1271_tx_complete_packet.

Added post recovery padding to adjust for potential security number
progress during the recovery process by the firmware and avoid
potential interop issues in encrypted networks.

wl12xx: Avoid recovery while one is already in progress

2011-06-27T12:05:15+00:00

During recovery work commands sent to the FW could fail and schedule
additional recovery work. Since the chip is going to be powered off,
avoid recursive recoveries.
