LGTM, thanks Robert

[PATCH net-next 0/2] mpls: Packet stats

[Robert Shearman]

This patchset records per-interface packet stats in the MPLS
forwarding path and exports them using a nest of attributes root at a
new IFLA_STATS_AF_SPEC attribute as part of RTM_GETSTATS messages:

[IFLA_STATS_AF_SPEC]
 -> [AF_MPLS]
  -> [MPLS_STATS_LINK]
   -> struct mpls_link_stats

The first patch adds the rtnl infrastructure for this, including a new
callbacks to per-AF ops of fill_stats_af and get_stats_af_size. The
second patch records MPLS stats and makes use of the infrastructure to
export them. The rtnl infrastructure could also be used to export IPv6
stats in the future.

[PATCH net-next 0/2] mpls: packet stats and ttl propagation config

[Robert Shearman]

This patch series implements new bits of mpls functionality: keeping
statistics on packets as they pass through the box and allowing ttl
propagation to be configured.
