Dear Rob,

from our experience MPLS in kernel is already implemented in the master 
OVS branch (2.3.9)

we succeeded in testing basic push/pop, we were also able to push 3 MPLS 
lables in a node

we have problems with multiple POPs in a node, as we posted in a recent 
message with subject "MPLS double POP bug?"

ciao
Stefano
