2010-11-15rt2x00: Add watchdog functions for HW queueIvo van Doorn1-2/+14
Add watchdog functions for managing the Queues inside the hardware. Normally the driver doesn't have much to do with these queues directly, but the Ralink drivers did implement watchdog functions for these. These watchdog functions are not triggered that often, compared to the other watchdog functions, but I have at least seen them trigger once or twice during a long stresstest run. v2: Add extra documentation for register fields Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Acked-by: Gertjan van Wingerde <gwingerde@gmail.com> Signed-off-by: John W.

2010-10-05rt2x00: Update comment about the AMPDU flag in the TXWIHelmut Schaa1-1/+7
During testing with AMPDUs it turned out that the rt2800 hw will aggregate consecutive frames with the same RA and TID when the first frame in a possible aggregate has set AMPDU=1 in the TXWI. If a following frame has set AMPDU=0 in its TXWI it might sill end up in the aggregate of the previous frame. Update the comment accordingly.

2010-10-05rt2x00: Improve TX status entry validationIvo van Doorn1-1/+13
The TX_STA_FIFO contains some information for identifying a outgoing frame, however matching by WCID and ACK status is not sufficient to 100% identify the macthing queue_entry structure (containing the SKB buffer) which belongs to the status report. Within TX_STA_FIFO we have a 4-bit field named PACKETID, which is currently used to encode the queue id. The queue ID is however limited to values from 0 to 3, which means 2 bits are sufficient to encode the value. With the remaining 2 bits we can encode a partial queue_entry index number. The value of PACKETID is not allowed to become 0, with the queue ID ranging from 0 to 3, at least one of the bits for the entry identification must be 1. That leaves us with 3 possible values we can still encode in the bits. Altough this doesn't allow 100% accurate matching of the TX_STA_FIFO queue to a queue_entry structure, it at least improves the accuracy. This allows us to better detect if we have missed the TX_STA_FIFO report, which in turn reduces the number of watchdog warnings regarding the TX status timeout.

2010-08-25rt2x00: Fix max TX power settingsIvo van Doorn1-0/+7
During initialization each driver reads the default TX power for each individual channel. However mac80211 only accepts the maximum value (which is also handled as default value). As a result, the TX power of the device was being limited to the default value, which is often quite low compared to the real maximum acceptable value. This patch allows each driver to set the maximum value on a per-channel basis which is forwarded to mac80211. The default value will be preserved for now, in case we want to update mac80211 to differentiate between the maximum and default txpower. This fixes bug complaining about limited TX power values like: https://bugzilla.kernel.org/show_bug.cgi?id=16358 Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Acked-by: Helmut Schaa <helmut.schaa@googlemail.com> Signed-off-by: John W.

2010-07-13rt2x00: Use pretbtt irq for fetching beacons on rt2800pciHelmut Schaa1-1/+7
Updating the beacon on pre tbtt instead of beacondone allows much lower latency in regard to TIM updates. Hence, use the pre tbtt interrupt for updating the beacon in rt2800pci (older devices don't provide a pre tbtt interrupt). Also, add a new driver flag to indicate if a driver has pre tbtt support or not and implement the according behavior in rt2x00lib.

2010-07-13rt2x00: Convert AGC value from descriptor to RSSI (dBm)Ivo van Doorn1-1/+1
The RSSI values in the RXWI descriptor aren't true RSSI values. Instead they are more like the AGC values similar to rt61pci. And as such, it needs the same conversion before it can be passed to rt2x00lib/mac80211. This requires the struct queue_entry to be passed to rt2800_process_rxwi rather then the skb structure which is contained in the queue_entry. This is required to obtain the lna_gain information from the rt2x00_dev structure. This fixes connection problems when using wpa_supplicant which would try to connect to the worst AP's rather then the best ones.
