Is the new API fixing the issue that the 6LoWPAN device creation is
done by iproute e.g.:

ip link add link wpan0 name lowpan0 type lowpan

or is there a special bluetooth API call needed, like the current case
with debugfs.
I know hcis are not netdevs, but it bothers me that we running into
two different worlds on how to deal with that and it just requires
"more" special bluetooth specific handling in user space applications.
Later more "netdev" capable link layers will maybe support 6LoWPAN and
then bluetooth might the only subsystem where different handling is
needed to do such job like that.

We maybe need to support a special handling in "ip link add" to map to
bluetooth instead moving that to people in user space?
