Not sure if I'm hijacking the thread, or if this patch is related, but
I've been seeing xHC hangs and timeouts with the dwc_3_1 controller.
Protocol Trace: https://0paste.com/59611 or
https://photos.app.goo.gl/54DGJJuH4kQa9Psy6
kernel trace: https://0paste.com/59613
This hang happens on transactions larger than 16K regardless of the
number of TRBs. I only see this on SS and not 2.0.
