My understanding of the in-kernel rtnetlink code is far from complete, 
but it doesn't seem to have much in the way of provisions for unit 
conversion, which would suggest no nice suffix-based ui as in tc, and ip 
is already doing some massaging of units on the display side for a 
couple of the other parameters, so I'm at something of a loss.
