Thanks for your time. I will work on your comments. Meanwhile please let me know the additional comments you have.

Could you please, add > notes about the difference to both: description of PUSH/POP_MPLS > and encap/decap(mpls) in the ovs-actions.7.rst ? > I think the description of encap/decap MPLS is little confusing and could be made better. I think it is better to fix the description than referring ENCAP/DECAP in push_mpls/pop_mpls & vice versa. I am planning to change like below Encap The ``encap(mpls(ethertype=....))`` adds an MPLS header at the start of the packet. Decap Otherwise, if the packet is encapsulated inside a MPLS header, removes the MPLS header and classifies the inner packet as mentioned in the packet type argument of the decap.
