That's kind of what I thought. But since my packets have no L2 header
in them, I don't know what hard_start_xmit can look at other than
skb->dst.
I guess hard_header could put some info in skb->cb -- is cb available
for net device use between hard_header and hard_start_xmit, or does
someone else still own it?
Thanks,
Roland
