Not AFAIK. Erni is being asked to rethink his approach here, and 
if we're going with a new command perhaps YNL should be on the table.

I'd be very interested to get a final ruling on YNL integration 
into iproute2 -- given its inability to work as a shared object /
library it's not unreasonable for the answer to be "no". 

The page pool sample in the kernel sources is very useful, I find
myself copying to various systems during debug. If there's no clear
path to YNL integration with iproute2 it's time for that sample to
be come a real CLI tool.
