Hi Felipe and Paul,
I am seeing an issue while testing iperf for USB ethernet gadget with
dwc3 controller in 2.0 mode. After debugging I figured out that:
1. Network gadget queues say 3 requests. (for IN endpoint)
2. It turns out with req.no_interrupt flag,
DWC3 driver issues START_TRANSFER

Hi Felipe,
In DWC3 driver, for three stage Control OUT transfer there is a check:
else if (!IS_ALIGNED(req-request.length, dep-endpoint.maxpacket)
(dep-number == 0)) {.
}
I understand that we check for alignment of sizes and if not we
prepare trb with maxpacket and enable

please prepend this with xudc_, it makes tracing a lot easier.
