Andy, there's a question for you below.

The Quectel EP06 (and EM06/EG06) LTE modem supports updating the USB
configuration, without the VID/PID or configuration number changing.
When the configuration is updated and interfaces are added/removed, the
interface numbers are updated. This causes our current code for matching
EP06 not to work
For stream capable endpoints, uas layer can queue mulpile requests on
single ep with different stream ids. So, there can be multiple pending
requests waiting to be transferred. This patch changes the code to check
for any pending requests waiting to be transferred on ep started_list and
calls __dwc
For stream capable endpoints, stream id related information
needs to be updated into DEPCMD while issuing START TRANSFER.
This patch does the same.

The stream capable endpoints require stream id to be given
when issuing START TRANSFER. While issuing no-op trb the
stream id is not yet known, so don't issue no-op trb's on
stream capable endpoints.

The present code in dwc3_gadget_ep_reclaim_completed_trb() will check
for IOC/LST bit in the event->status and returns if IOC/LST bit is
set. This logic doesn't work if multiple TRBs are queued per
request and the IOC/LST bit is set on the last TRB of that request.
Consider an example where a queue
Availability of TRB's is calculated using dwc3_calc_trbs_left(), which
