As it breaks g_ether on my Baytrail FFRD8 device. Everything starts out

Me too, but I can see no other way here. The code is simpler without
locking, indeed, but locking is nee
by moving trace_dwc3_ep_queue() from dwc3_gadget_ep_queue()
to __dwc3_gadget_ep_queue() after usb_request is properly
initialized, makes for a better output always showing a
request with 0 actual and -115 (-EINPROGRESS) status.

The race may happen when a device (e.g. YOTA 4G LTE Modem) is
unplugged while the system is downloading a large file from the Net.
Hardware breakpoints and Kprobes with delays were used to confirm that
the race does actually happen.
The race is on skb_queue ('next' pointer) between usbnet_stop()

Separate the download and boot mode code from download_fw() into two new
helper functions: do_download_mode() and do_boot_mode(), and fix formatting
in some of the comments.

While working on a previous patchset for this driver [1] we were hampered
by the fact that download_fw() is very long and its return paths are so
complicated that we were compelled to the put the request_firmware() call
in edge_startup(), when it much more naturally belong

The bulk queue tests are used to show 'best performance' for bulk
transfer, we are often asked this question by users.
It's result should be very close to IC simulation, in order
to get that, the device side should also need to prepare enough
queue.
