Updates to the Ethernet/RNDIS gadget driver (mostly for RNDIS):
- Fix brown-paper bag goof with RNDIS packet TX ... the wrong length
field got set, so Windows would ignore data packets it received.
- More consistent handling of CDC output filters (but not yet hooking
things up so RNDIS uses the mechanism).
- Zerocopy RX for RNDIS packets too (saving CPU cycles).
- Use the pre-allocated interrupt/status request and buffer, rather
than allocating and freeing one of each every few seconds (which
could fail).
- Some more "sparse" tweaks, making both dual-speed and single-speed
configurations happier.
- RNDIS speeds are reported in units of 100bps, not bps.
Plus two minor cleanups (whitespace, messaging).
