Subject: [PATCH WIP RFC 0/3] mpls: support for ler

From: Roopa Prabhu <roopa@...ulusnetworks.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.

Roopa Prabhu (3):
  lwtunnels: basic infra for light weight tunnels like mpls
  ipv4 fib: lwtunnel handling
  mpls: register lwtunnel ops
