Browse Source 
The recent mailing list thread about MPLS reminded me that the FAQ needs an
update.

@ -1239,12 +1239,14 @@ A: Before version 1.11, Open vSwitch did not support MPLS. That is,
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
datapaths will be supported, but MPLS processing always happens in
userspace either way, so kernel datapath performance will be
disappointing.
Open vSwitch version 2.3 can 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 datapaths will be
supported, but MPLS processing always happens in userspace either
way, so kernel datapath performance will be disappointing.
Open vSwitch version 2.4 will have kernel support for MPLS,
yielding improved performance.
Q: I'm getting "error type 45250 code 0". What's that?
