Occasionally the hardware can send out tx status information with the wrong TID. In that case, the BA status cannot be trusted and the aggregate must be retransmitted. Signed-off-by:

If the receive path gets stuck, a full hardware reset is necessary to recover from it. If this happens during a scan, the whole scan might fail, as each channel change bypasses the full reset sequence. Fix this by resetting the fast channel change flag if stopping the receive path fails. This will reduce the number of error messages that look like this: ath: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x40000020 Signed-off-by:

On AR9285, the antenna switch configuration register uses more than just 16 bits. Because of an arbitrary mask applied to the EEPROM value that stores this configuration, diversity was broken in some cases, leading to a significant degradation in signal strength. Fix this by changing the callback to return a 32 bit value and remove the arbitrary mask. Signed-off-by:

All callback functions are gathered in rt2x00dev->ops except for the callback functions which are used in rt2800lib to acces rt2800pci/usb. Move the priv pointer from rt2x00dev to rt2x00dev->ops and rename it to drv to make it obvious that it is the driver callback structure. Signed-off-by:

Currently rt2x00 uses the TSF_SYNC_BEACON mode for all beaconing interface types. However, TSF_SYNC_BEACON is meant for IBSS networks and thus implements TSF merging in the hardware. Rename TSF_SYNC_BEACON to TSF_SYNC_ADHOC to better express its purpose and introduce the missing TSF sync mode TSF_SYNC_AP_NONE which should be used for beaconing modes that don't need TSF merging.

Using the set_tim callback without managing the DTIM count and the broad- and multicast buffering in hw, fw or the driver results in wrong DTIM count values being sent out in beacons. Since all PCI drivers fetch new beacons periodically and hence get an updated TIM we can just remove the set_tim callback from these. The rt2x00 USB drivers don't update the beacon periodically and thus rely on the set_tim callback to get a correct TIM for beacon transmission. USB devices still suffer from the DTIM count being wrong under some circumstances but removing the set_tim callback from these would cause more harm then good. Signed-off-by:

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. Signed-off-by:

Although mac80211 buffers broad- and mutlicast frames for us in AP mode we still have to send them out after a DTIM beacon. Implement this behavior by sending out the buffered frames when the beacondone interrupt is processed. Signed-off-by:

Since all rt2x00 PCI drivers use threaded interrupts now we don't need to schedule a work just to update the beacon. The only place where the beacon still gets updated in atomic context is from the set_tim callback. Hence, move the work scheduling there. Signed-off-by:

Use threaded interrupts for all rt2x00 PCI devices. This has several generic advantages: - Reduce the time we spend in hard irq context - Use non-atmic mac80211 functions for rx/tx Furthermore implementing broad- and multicast buffering will be much easier in process context while maintaining low latency and updating the beacon just before transmission (pre tbtt interrupt) can also be done in process context.

Implement watchdog monitoring for USB devices (PCI support can be added later). This will determine if URBs being uploaded to the hardware are actually returning. Both rt2500usb and rt2800usb have shown that URBs being uploaded can remain hanging without being released by the hardware. By using this watchdog, a queue can be reset when this occurs. For rt2800usb it has been tested that the connection is preserved even though this interruption. Signed-off-by:

Currently vgc_level_reg and vgc_level are equal to eachother, while the purpose of vgc_level_reg is the value last written to the register and is remembered through link tuning resets. The vgc_level is the currently active level, which is reset during link tuning resets. The usage of these variables depends on the drivers, some drivers need both, while others need only one of the two. Signed-off-by:

Rename CONFIG_DISABLE_LINK_TUNING to DRIVER_SUPPORT_LINK_TUNING Link tuning support is not only based on EEPROM decisions, but also if the device actually supports it. Currently only rt2500usb doesn't support link tuning because of hardware problems. But rt2800usb is also suspected of having problems with link tuning. Signed-off-by:

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. Signed-off-by:

In hostap_add_interface() we do: sprintf(dev->name, "%s%s", prefix, name); dev->name has IFNAMSIZ (16) characters. prefix is local->dev->name. name is "wds%d" strlen() returns the number of characters in the string not counting the NULL so if we have a string with 11 characters we get "12345678901wds%d" which is 16 characters and a NULL so we're past the end of the array.

Ever since mac80211/drivers are no longer fully in charge of keeping track of the auth status, trying to make them do so will fail. Instead of warning and reporting the deauthentication to userspace, cfg80211 must simply ignore it so that spurious deauthentications, e.g. before starting authentication, aren't seen by userspace as actual deauthentications.

This patch is a complete rewrite of the scanning code. It now includes a state machine to scan all four possible sets of channels independently: 2.4GHz active, 2.4GHz passive, 5GHz active and 5GHz passive. The wl1271 firmware doesn't allow these sets to be mixed, so up to several scan commands have to be issued. This patch also allows scanning more than 24 channels per set, by breaking the sets into smaller parts if needed (the firmware can scan a maximum of 24 channels at a time). Previously, the scanning code was erroneously scanning all channels possible actively, not complying with the CRDA values. This is also fixed with this patch. Signed-off-by:

The scanning code is going to get a bit more complex, with proper support for active/passive scans together with 2.4GHz and 5GHz. In the future, also a new type of scan (periodic scan) will be added. When all this is implemented, the code is going to be much more complex, so we'd better separate it into a separate file. This patch doesn't have any impact on functionality. Signed-off-by:
