[PATCH v2 0/2] 6lowpan default hardware address

[PATCH v2 0/2] 6lowpan default hardware address

[Alan Ott]

Alexander Aring suggested that devices desired to be linked to 6lowpan
be checked for actually being of type IEEE802154, since IEEE802154 devices
are all that are supported by 6lowpan at present.

Alan Ott (2):
  6lowpan: Only make 6lowpan links to IEEE802154 devices
  6lowpan: Sync default hardware address of lowpan links to their wpan

[PATCH v2 1/2] 6lowpan: Only make 6lowpan links to IEEE802154 devices

[Alan Ott]

Refuse to create 6lowpan links if the actual hardware interface is
of any type other than ARPHRD_IEEE802154.

[PATCH v2 2/2] 6lowpan: Sync default hardware address of lowpan links to their wpan

[Alan Ott]

When a lowpan link to a wpan device is created, set the hardware address
of the lowpan link to that of the wpan device.
