Well, there *is* "bridged netflow" in SXE2 or SXF (need to look that up),
but I'm not sure whether you can use the routing engine inside the box
*and* use bridged netflow "from the port to the routing engine" to
get MAC accounting data...

Seems I need to read some docs and run some testing :-)

(OTOH, *if* the box can do this, it should be able to present the data
in "standard MAC accounting" format)
