Exactly.

It's not.

Please test: create a bridge with STP disabled, add an interface to the
bridge and set that interface down. You get the message "... entering
forwarding state". That's wrong because it's "about to enter" disabled
state some lines later.

All other (4) calls to br_log_state are located after the state change,
see for example br_stp_enable_port() just some lines above the patch.

Wolfgang
