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.

If existing bpf features in iproute2 work fine with version 0.1.0, what
is the justification for an arbitrary requirement for iproute2 to force
users to bump libbpf versions just to use iproute2 from v5.11?
