In the past all the rings were allocated with cycle state equal to 1. Now the driver may expand an existing ring, and the new segments shall be allocated with the same cycle state as the old one. This affects ring allocation and cached ring re-initialization.

In the past, the room_on_ring() check was implemented by walking all over the ring, which is wasteful and complicated. Count the number of free TRBs instead. The free TRBs number should be updated when enqueue/dequeue pointer is updated, or upon the completion of a set dequeue pointer command.

The latest released errata for USB2.0 ECN LPM adds new fields to USB2.0 extension descriptor, defines two BESL values for device: baseline BESL and deep BESL. Baseline BESL value communicates a nominal power savings design point and the deep BESL value communicates a significant power savings design point. If device indicates BESL value, driver will use a value count in both host BESL and device BESL. Use baseline BESL value as default.

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.

Use the new cdc-wdm subdriver interface to create a device management device even for USB devices having a single combined QMI/wwan USB interface with three endpoints (int, bulk in, bulk out) instead of separate data and control interfaces.

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.

This driver can be used as a subdriver of another USB driver, allowing it to export a Device Managment interface consisting of a single interrupt endpoint with no dedicated USB interface. Some devices provide a Device Management function combined with a wwan function in a single USB interface having three endpoints (bulk in/out + interrupt). If the interrupt endpoint is used exclusively for DM notifications, then this driver can support that as a subdriver provided that the wwan driver calls the appropriate entry points on probe, suspend, resume, pre_reset, post_reset and disconnect. The main driver must have full control over all interface related settings, including the needs_remote_wakeup flag. A manage_power function must be provided by the main driver. A manage_power stub doing direct flag manipulation is used in normal driver mode.
