I think bumping the minimal version of libbpf with every iproute2 release
is necessary as well.
Today iproute2-next should require 0.2.0. The cycle after it should be 0.3.0
and so on.
This way at least some correlation between iproute2 and libbpf will be
established.
Otherwise it's a mess of versions and functionality from user point of view.
