This will need to change when we add new OpenFlow versions, but I
don't expect that new OpenFlow versions will actually change anything
in the barrier request. So I'd be inclined to do something like:
raw = (version == OFP10_VERSION
? OFPRAW_OFPT10_BARRIER_REQUEST
: OFPRAW_OFPT11_BARRIER_REQUEST);
instead of a switch that definitely needs to be updated.
Thanks,
Ben.
