The recent mailing list thread about MPLS reminded me that the FAQ needs an

    packet.  Kernel datapath support is unchanged from earlier
    versions.
 
-   Open vSwitch version 2.2 will be able to match, push, or pop up to
-   3 MPLS labels.  Looking past MPLS labels into the encapsulated
-   packet will still be unsupported.  Both userspace and kernel

 Q: I'm getting "error type 45250 code 0".  What's that?
