 Does IPOIB in this stack support transparent fail over between ports and

I am working on a patch to the linux bonding driver which will allow it 
to enslave also IPoIB devices for the active-backup mode. I will send an 
RFC to netdev for review next week. Does this meets your needs?

Does by virtual IP you mean an ***alias address*** assigned at one point 
of time to one ipoib device and in another point of time (eg during 
fail-over) to a second ipoib device?  does this approach have any 
advantage on the bonding approach?

Or.

Supporting IPOIB fail over with the Bonding driver will work - we
currently use this for GE, etc.

You can also get failover with IPoIB if you're willing to use SCTP as
the transport.
