From: Roopa Prabhu <ro...@cumulusnetworks.com> This is still WIP and incomplete. Posting it here because of the other discussions happening around mpls ler in the context of Roberts code and I happened to mention this implementation.
This was in response to earlier email thread with Eric on net-next of possibly using xfrm style stacked destination approach. I introduce a new set of tunnel ops for light weight tunnels (lwt), but this could be merged with the other ip_tunnels code if possible. I had this code for 3.2 kernel initially, and as I was pulling out code, I realize i had to separate out some other mpls code that i have been working on and quite likely this will not even compile. Sorry abt that.
