Why TUNSETLINK to ARPHRD_6LOWPAN

[alexaring]

Hi,

do you have a good reason why setting the interface type to ARPHRD_6LOWPAN if defined? In case of Linux, do you use any feature which is provided by the in-kernel 6LoWPAN feature? @mcr and I currently try to solve some issues inside the kernel do deal with this tun feature and probably like to disallow to change to this type which ends in a -ENOTSUPP or something else.
