Experimental support for FreeBSD. Requires a fairly recent version
of FreeBSD with pkgng installed. The ovs commands remain exactly
the same, however it is necessary to replace invocations of the
ip command with and equivalent ifconfig command in FreeBSD. Also,
appropriate setting of the datapath is also required to make a
bridge actually appear as an interface.
Specified the default expected parameters for vswitch::ovs when
used under FreeBSD. Also, some minor changes were made to the
vswitch::ovs parameters, most notably the addition of a status
parameter for the required services (ovs-vswitchd,ovsdb-server).
