I'm trying to take "hand-built" sk_buffs with little more than some data
and a dev member and push them to the NIC for transmission. I would
like to simply give them to dev_queue_xmit. Does anybody know what
state I should have them in before handing them to dev_queue_xmit? Should skb->data point to the start of a MAC header or an IP header?

Also, given an IP address in skb->nh.iph->daddr, what's the easiest way
to get the appropriate MAC address?

use ip_route_output_key() and then skb->dst->output(), that way it will work on all media
and you don't have to care about l2 resolving at all.
