Maybe I wasn't accurate/clear, we do mangle outgoing/incoming ARP 
packets, from/to Ethernet ARPs
to/from IPoIB ARPs.

guests don't interact with IB, I assume you referred to dom0 code, eIPoIB or
another driver in the host. But what mapping exactly? and remember that
this code (VM through eipoib) can talk to any IPoIB element on the 
fabric, native,
virtualized,  HW/SW gateways, etc etc.
