[edk2-devel] [edk2-platforms: PATCH 0/3] Platform/RPi3: Improve timeout handling in DwUsbHostDxe

[Pete Batard]

Networking applications (e.g. iPXE) might experience failures when submitting
a bulk IN for the NIC's RX endpoint, because the bulk IN (correctly) times out
when no received packet is waiting, but DwUsbHostDxe.c treats this as a fatal
error.

With these patches, iPXE is able to successfully download a 128MB test file
via HTTP.

Michael Brown (3):
  Platform/RPi3: Use Wait4Bit return value consistently
  Platform/RPi3: Gracefully disable USB channel after a timeout
  Platform/RPi3: Reduce debug noise when using a USB network device
