Scott Feldman says:
====================
rocker cleanups
Pushing out some rocker cleanups I've had in my queue for a while. Nothing
major, just some sync-up with changes that already went into device code
(hard-coding desc err return values and lport renaming). Also fixup
port fowarding transitions prompted by some DSA discussions about how to
restore port state when port leaves bridge.
