because : those tow packages used rc.d. so we only need to install them

inherit autotools update-rc.d

INITSCRIPT_PACKAGES = "${PN}-switch ${PN}-controller"
INITSCRIPT_NAME_${PN}-switch = "openvswitch-switch"
INITSCRIPT_PARAMS_${PN}-switch = "defaults 71"

INITSCRIPT_NAME_${PN}-controller = "openvswitch-controller"
INITSCRIPT_PARAMS_${PN}-controller = "defaults 72"

I will send V2 tomorrow
