That was just an example because someone mentioned PPP earlier.
Originally, this came from someone (Octavian?) trying to setup
a gazillion netdevs for testing purposes and then needing to
do "ip link ls dummy*" which causes a gazillion messages between
kernel and user space and all the filtering of what dummy* being
done in user space.

You still havent said what you want this grouping for. What is your
use case? ;->
