none of the implementations out there are complete nor can compete
with iproute2.
iproute2 is maintained by netdev community and always is up-todate
with the latest
networking api.

Nothing against pyroute2 but we wrote our own for other reasons and we
carry additional burden of maintaining it and keeping it up-todate for
every networking api..
that gets added to iproute2 (and the implementation of netlink
is often very easy in C).

Also, for external automation and orchestration tools (to whom this
patch-set is addressed),
there is no reason for them to write and maintain their own tools
using netlink when they
can use iproute2 directly to create a link or query its properties.
