Hi Folks,

We have a cluster with Voltaire/HP HCAs.  The port GUIDs are HP's (OUI == 
0x0018FE), rather than Voltaire's (OUI == 0x0008F1).  The result is that the 
MAC addresses generated by IPoIB are of the locally administered address type - 
0x02 in the first byte - which breaks DHCP support.

Is there some algorithm for converting these GUIDs be added to IPoIB?  Is it 
the same algorithm as for Voltaire GUIDs, just with a different OUI?

Thanks!
-Fab
