Hi Chen

Thats a good suggestion indeed.

Networking patches should be sent to netdev@...r.kernel.org (added in
CC)

This list only cares about recent generic kernels, not RedHat ones.

If you want to provide a patch, please base it on David Miller net-next
[1] tree, and make it official (read Documentation/SubmittingPatches for
general advices)

By the way, the %8s should be replaced by %s, there is no need to make
/proc/net/ipv6_route 'beautiful'. In the past, it was *needed* because
each line had to be of a given length, but its not anymore the case.

Thanks
