could you pls make your changes sepcific to the d-link product ?
b/c your patch will break any DMAC adress that starts with 0000.
an idea would be to match against the DLINK OUI in the source MAC address.

Hello everybody,
I'm using two D-Link DWL-2000 AP+ in bridge-mode. They use some odd
protocol. Before 802.2 header there is two bytes of src mac address. I
don't know, why they do so, but I made a little patch to decode this
packets.
Best Regards, m0sia.
