Yes, it's not macvlan to blame, I just tested it in SR-IOV scheme with igb/igbvf and
I see the same problem, only ping that goes through / targeted to the IP address of the first
VF device routing hit works, which means SR-IOV isn't really usable with 2.6.31 when you want 
a multiple VMs scheme, each attached to a different VF and all VMs on the same network segment.

Or.
