2012-03-12iwlwifi: convert bad state message into warningJohannes Berg1-14/+14
Looking at logs, I see that we did get the bad state message a few times for some reason, but it doesn't indicate why or where it came from, so make it a warning in order to identify it.

Mohammed Shafi ran into [1] the SEQ_RX_FRAME workaround warning with a statistics notification, this means we can't just remove it as we'd hoped. Abstract it out so that the higher layer can configure this as a kind of "filter" in the transport.

2012-03-12rt2x00: Fix beacon skew in rt2800pciHelmut Schaa2-0/+33
rt2800pci is suffering from beacon skew in AP mode. Some powersaving clients (like VOIP phones) are getting into trouble after some time when the beacon skew is getting too big. The ralink legacy drivers contain a function that indicates that the beacon timer is off by 1us per tbtt. And this function works around that by reducing the beacon interval for every 64th beacon transmission by 64us (the smallest possible value). Do the same in rt2800pci. This allows proper powersaving when rt2800pci is used in AP mode. Signed-off-by: Helmut Schaa <[email protected]> Signed-off-by: John W. Linville <[email protected]>

2012-03-12rt2x00: fix random stallsStanislaw Gruszka3-1/+17
Is possible that we stop queue and then do not wake up it again, especially when packets are transmitted fast. That can be easily reproduced with modified tx queue entry_num to some small value e.g. 16. If mac80211 already hold local->queue_stop_reason_lock, then we can wait on that lock in both rt2x00queue_pause_queue() and rt2x00queue_unpause_queue(). After drooping ->queue_stop_reason_lock is possible that __ieee80211_wake_queue() will be performed before __ieee80211_stop_queue(), hence we stop queue and newer wake up it again. Another race condition is possible when between rt2x00queue_threshold() check and rt2x00queue_pause_queue() we will process all pending tx buffers on different cpu. This might happen if for example interrupt will be triggered on cpu performing rt2x00mac_tx(). To prevent race conditions serialize pause/unpause by queue->tx_lock.

Adding the Pantech UML290 and all non-QDL Gobi device IDs from the qcserial driver now that we have support for shared net/QMI USB interfaces. Most of these are not yet tested with this driver, but should be mostly identical to tested devices, except for device IDs. Gobi devices provide several different interfaces (serial/net/other) using the exact same class, subclass and protocol values. This driver will only support the net/QMI function while there are other drivers supporting other device functions. The net/QMI interface number may also differ from device to device. It has been noted that all the other interfaces have additional functional descriptors, so we use that to detect the interface supported by this driver.

2012-03-09net: usb: qmi_wwan: New driver for Huawei QMI based WWAN devicesBjørn Mork3-0/+251
Some WWAN LTE/3G devices based on chipsets from Qualcomm provide near standard CDC ECM interfaces in addition to the usual serial interfaces. The Huawei E392/E398 are examples of such devices. These typically cannot be fully configured using AT commands over a serial interface. It is necessary to speak the proprietary Qualcomm MSM Interface (QMI) protocol to the device to enable the ethernet proxy functionality. The devices embed the QMI protocol in CDC on the control interface, using standard CDC commands and notifications. The do not otherwise use CDC commands for the ethernet function. This driver does therefore not need access to any other aspects of the control interface than the descriptors attached to it. Another driver, cdc-wdm, will provide userspace access to the QMI protocol independently of this driver. To facilitate this, this driver avoids binding to the control interface, and uses only the associated data interface after parsing the common CDC functional descriptors on the control interface. You will want both the cdc-wdm and option drivers as companions to this driver, to have full access to all interfaces and protocols exported by the device.

Only the ucode_flags are needed to configure the transport layer, not the sku which _must_ be set after the EEPROM is read.
