Actually, I'm ok for your suggestion that using a existing option(-m) to
export all memory information. But with a new option is better for us.

Maybe some people use latest iproute source with under kernel 3.3.0, some don't.
-m option will take different user experience, specially for UDP socket.
Currently -m option has no effect on UDP socket which i will submit another patch
to export memory information for. new option, fresh experience.

(Exporting out memory information will help us to analysis dropped packets 
which recorded in RcvbufErrors and SndbufErrors.)
