openvswitch kernel module not shipped

[Stefan Kooman]

openvswitch-switch package does not ship a openvswitch kernel module. Therefore ovs-vswitch cannot start (unable to modprobe the kernel module), and hence openvswitch-switch cannot start.

Kernel modules are provided by the kernel packages linux-modules and linux-modules-extra. openvswitch is in -extras:
