there is already a way to change eth/ib via
echo 'eth' > /sys/bus/pci/drivers/mlx4_core/0000:02:00.0/mlx4_port1

sounds like this is another way to achieve the same?
Why not hide echo/cat in iproute2 instead of adding parallel netlink api?
Or this is for switches instead of nics?
Then why it's not adding to switchdev?
