Hi, this patch restricts 6lowpan to IEEE802154 devices (in order to make sure that the BUG_ONs in mib.c are not triggered).
I am however currently trying to get 6lowpan running on a tun device. This would enable to use the Linux 6lowpan stack with e.g. Contiki's tunslip6. The only changes needed to enable 6lowpan-on-tun are to replace the calls to ieee802154_mlme_ops(real_dev)->get_XXX(real_dev); where XXX = pan_id|short_addr|dsn Would it be acceptable for the maintainers to have module parameters to 6lowpan specify pan_id and short_addr (while counting dsn in the module itself) when not running on top of a IEEE802154 device?
