I've written protocol stacks for other OSes but not Linux.
Can I set the protocol in mac802154_process_data()?
skb->protocol = htons(ETH_P_6LOWPAN);
skb->pkt_type = PACKET_HOST;
if (in_interrupt())
return netif_rx(skb);
And then register my protocol in af_ieee802154 as part of the
PF_IEEE802154 family?
What would be a good example for me to follow as a model of the
architecture of the protocol?
In RFC4944 6lowpan has a dispatch byte at the front. 00xxxxxx is
reserved for other protocols. Does that happen to mesh with ZigBee,
etc?

A diagram showing the relationships of the components and mapping them
to the 802.11 equivalents would make a good slide.
