oxm_value
itself is not at the start of the packet, and is not aligned within the
ofp_ox_match. I'm not familiar enough with the open flowz to know if
ofp_ox_match is guaranteed to start at a 4-byte alignment (which would
push oxm_value out to an 8 byte alignment), but I suspect that's not the
case.

well, and based

It was easy to implement, so I added it and sent a patch. If

My website generator is a little stupid at times. It generates
