The driver_info field that is used for describing each of the usb-net
drivers using the usbnet.c core all declare their information as const
and the usbnet.c itself does not try and modify the struct.
It is therefore a good idea to make this const in the usbnet.c structure
in case anyone tries to modify it.

Recent firmware revisions have added the ability to force
these modems to USB2 mode, hiding their SuperSpeed
capabilities from the host. The driver has been using the
SuperSpeed capability, as shown by the bcdUSB field of the
device descriptor, to detect the need to enable the DTR
quirk. This method fails when the modems are forced to
USB2 mode by the modem firmware.
Fix by unconditionally enabling the DTR quirk for the
affected device IDs.

Quectel EP06 (and EM06/EG06) supports dynamic configuration of USB
interfaces, without the device changing VID/PID or configuration number.
When the configuration is updated and interfaces are added/removed, the
interface numbers change. This means that the current code for matching
EP06 does not work.
This patch removes the current EP06 interface number match, and replaces
it with a match on class, subclass and protocol. Unfortunately, matching
on those three alone is not enough, as the diag interface exports the
same values as QMI. The other serial interfaces + adb export different
values and do not match.
The diag interface only has two endpoints, while the QMI interface has
three. I have therefore added a check for number of interfaces, and we
ignore the interface if the number of endpoints equals two.

When unplugging an r8152 adapter while the interface is UP, the NIC
becomes unusable. usb->disconnect (aka rtl8152_disconnect) deletes
napi. Then, rtl8152_disconnect calls unregister_netdev and that invokes
netdev->ndo_stop (aka rtl8152_close). rtl8152_close tries to
napi_disable, but the napi is already deleted by disconnect above. So
the first while loop in napi_disable never finishes. This results in
complete deadlock of the network layer as there is rtnl_mutex held by
unregister_netdev.
So avoid the call to napi_disable in rtl8152_close when the device is
already gone.
The other calls to usb_kill_urb, cancel_delayed_work_sync,
netif_stop_queue etc. seem to be fine. The urb and netdev is not
destroyed yet.

The USB completion callback does not disable interrupts while acquiring
the lock. We want to remove the local_irq_disable() invocation from
__usb_hcd_giveback_urb() and therefore it is required for the callback
handler to disable the interrupts while acquiring the lock.
The callback may be invoked either in IRQ or BH context depending on the
USB host controller.
Use the _irqsave() variant of the locking primitives.
