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.
Scott Feldman (3):
rocker: fix non-portable err return codes
rocker: rename lport to pport
rocker: put port in FORWADING state after leaving bridge

The rocker device returns error codes if something goes wrong with descriptor
processing. Originally the device used standard errno codes for different
errors, but since those errno codes aren't portable across ARCHs, the device
now returns hard-coded error codes that stay constant across diff ARCHs. Fix
driver to use those same hard-coded values.

This is just a rename of physical ports from "lport" to "pport". Not a
functional change. OF-DPA uses logical ports (lport) for tunnels, but the
driver (and device) were using "lport" for physical ports. Renaming physical
ports references to "pport", freeing up "lport" for use later with tunnels.

From: Scott Feldman <sfeldma@gmail.com>
Cleanup the port forwarding state transitions for the cases when the port
joins or leaves a bridge, or is brought admin UP or DOWN. When port is
bridged, we can rely on bridge driver putting port in correct state using
STP callback into port driver, regardless if bridge is enabled for STP or not.
When port is not bridged, we can reuse some of the STP code to enabled or
disable forwarding depending on UP or DOWN.
Tested by trying all the transitions from bridge/not bridge, and UP/DOWN, and
verifying port is in the correct forwarding state after each transition.

You might as well use dense error numbers and then an array for the conversion.
If you want to avoid confusion, then offset the error numbers from zero.
