I have mixed feelings about this.  Yes, it makes it easier to identify
packets coming from Open vSwitch, but I'm not sure that that is too
useful (has anyone on the list ever had a need for it?) and it kind of
gives up control over Nicira's OUI.

Also, there are only 22 bits of randomness instead of 46 if we fix all
those bits.

The dpid is a little different, since it isn't used as a source MAC
anywhere as far as I know.
