NAK to this backwards-incompatible change.
At this point there's no way to know how many drivers it breaks ... I do know that counting such SKBs as errors has previously turned up link-level errors, and thus led to bugfixes.

The canonical reason the SKB would be empty is because after rx_fixup() removed all header and trailer data, there was no packet body left. Which is likely a link error, and has been worth accounting as such in the past (turned up bugs on TX or RX sides).

I'd far rather see that driver fixed, than see the core usbnet framework broken to avoid such fixes to a very new driver ...
