Hi Greg,

We have a usb core function that handles these "short reads are an
error" issue. Perhaps usbnet_read_cmd() should be converted to use it
instead?
I thought about it. I am not sure, that there are no callers, that
expect various length data. I remember, that I met such problem in atusb
driver, but it uses plain usb API.
I believe, we can provide new usbnet API, that will use
usb_control_msg_{recv,send} and сarefully convert drivers to use it.
When there won't be any callers of the old one we can just rename it.
I might be missing something about usbnet, so, please, correct me if I
am wrong here :)
With regards,
