Hub-initiated LPM is not good for USB communications devices. Comms devices should be able to tell when their link can go into a lower power state, because they know when an incoming transmission is finished. Ideally, these devices would slam their links into a lower power state, using the device-initiated LPM, after finishing the last packet of their data transfer. If we enable the idle timeouts for the parent hubs to enable hub-initiated LPM, we will get a lot of useless LPM packets on the bus as the devices reject LPM transitions when they're in the middle of receiving data. Worse, some devices might blindly accept the hub-initiated LPM and power down their radios while they're in the middle of receiving a transmission. The Intel Windows folks are disabling hub-initiated LPM for all USB communications devices under a xHCI USB 3.0 host. In order to keep the Linux behavior as close as possible to Windows, we need to do the same in Linux. Set the disable_hub_initiated_lpm flag for for all USB communications drivers. I know there aren't currently any USB 3.0 devices that implement these class specifications, but we should be ready if they do.

Some RNDIS devices include a bogus CDC Union descriptor pointing to non-existing interfaces. The RNDIS code is already prepared to handle devices without a CDC Union descriptor by hardwiring the driver to use interfaces 0 and 1, which is correct for the devices with the bogus descriptor as well. So we can reuse the existing workaround.

The MC77xx devices can operate in two modes: "Direct IP" or "QMI", switchable using a password protected AT command. Both product ID and USB interface configuration will change when switched. The "sierra_net" driver supports the "Direct IP" mode. This driver supports the "QMI" mode. There are also multiple possible USB interface configurations in each mode, some providing more than one wwan interface. Like many other devices made for Windows, different interface types are identified using a static interface number. We define a Sierra specific interface whitelist to support this.

Commit 4231d47e(net/usbnet: avoid recursive locking in usbnet_stop()) fixes the recursive locking problem by releasing the skb queue lock, but it makes usb_unlink_urb racing with defer_bh, and the URB to being unlinked may be freed before or during calling usb_unlink_urb, so use-after-free problem may be triggerd inside usb_unlink_urb. The patch fixes the use-after-free problem by increasing URB reference count with skb queue lock held before calling usb_unlink_urb, so the URB won't be freed until return from usb_unlink_urb.

asix_rx_fixup() is complex, and does some unnecessary memory copies (at least on x86 where NET_IP_ALIGN is 0) Also, it tends to provide skbs with a big truesize (4096+256 with MTU=1500) to upper stack, so incoming trafic consume a lot of memory and I noticed early packet drops because we hit socket rcvbuf too fast. Switch to a different strategy, using copybreak so that we provide nice skbs to upper stack (including the NET_SKB_PAD to avoid future head reallocations in some paths) With this patch, I no longer see packets drops or tcp collapses on various tcp workload with a AX88772 adapter.

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.
