Do you see any scale problems with using notifiers ?. as you know these ascis can scale to
32k-128k routes.

I don't see any problem there. What do you think might be wrong?

we had seen some overheads with link notifiers in older kernels with
large number of links flaps.
But that could have been due to rtnl lock. don't have any more data
than that. so, ignore that.
I don't see anything obvious from perf perspective....rtnl is already
held. but, thought i did just ask.
