[PATCH net-next 0/6] net: another round of extack handling for routing

[David Ahern <dsahern@gmail.com>]

This set focuses on passing extack through lwtunnel and MPLS with
additional catches for IPv4 route add and minor cleanups in MPLS
encountered passing the extack arg around.

David Ahern (6):
  net: ipv4: Add extack message for invalid prefix or length
  net: lwtunnel: Add extack to encap attr validation
  net: plumb extack arg down to lwtunnel build state
  net: Fill in extack for mpls lwt encap
  net: mpls: Add extack messages for route add and delete failures
  net: mpls: minor cleanups
