I agree with the cost too.

Robert, I was thinking of responding to your series to add netlink stats for 
AF_MPLS in
 rtnl_af_ops (similar to  IFLA_INET6_STATS). But, soon realized that it is 
currently used by ipv6 alone
and it also ended up with a skip filter (RTEXT_FILTER_SKIP_STATS). So, 
extending that interface for
mpls is not the right thing to do either.

There is work being done for a separate netlink infrastructure for stats.
I would wait for that infrastructure to be ready to add mpls stats. It should 
be available soon.

thanks,
Roopa
