NOTE: order of components start at boot
/etc/rc.d/rc3.d/S09openvswitch
/etc/rc.d/rc3.d/S10network

reverse at shutdown.
So possible for a restart of all the stack you could run something
like this in a unique command if you are not directly at console
# service network stop; service openvswitch stop; service openvswitch
start; service network start

BTW: you could find the config I'm using in this thread:

This is the output of the command above on my system (after the line
regarding shutdown of bond0 there is one minute before you see on
terminal all the other lines)
