But iproute2 assumes that the ifindex is unique within all net
namespaces. This isn't true anymore
after commit aa79e66eee5d525e2fcbd2a5fcb87ae3dd4aa9e9 "net: Make
ifindex generation
per-net namespace".

However, in order to do the right thing iproute2 would have to know
the ifindex of the
link device _and_ its associated netns.

Not sure how to deal with that ...
