silence ifconfig errors related to carp demotion at boot time This happens when nsh is started by /etc/rc.d/nsh during boot. The /etc/rc script starts package scripts with carp-interlock already enabled, and both ifconfig and nsh would attempt to reset the carp demotion counter. Generally, this is harmless, apart from an error message displayed by ifconfig which might mislead users into assuming there was a problem: starting package daemons: nsh. ifconfig: carp: SIOCSIFGATTR: Invalid argument To avoid this issue, nsh can check whether the demotion counter has already been set to the desired level and only change the counter if changing it is indeed required.

fix typo in exit command in bridge commands struct This is the intended change from commit cfd60254

! without arguments should not fork a new shell This Diff changes the behaviour of nsh interactively by checking if ! has been entered without any arguments, if the user is in global config mode or privileged mode the user is returned to the same prompt. if the user is in interface config mode or bridge config mode the user is returned to the global configuration mode This is to facilitate users copying and pasting nshrc configuration from one device to another interactively.
