This method you describe should just work -- mbuf_copydata() walks
down the mbuf chain the same way the above code computes the length.
How do you know that you are not seeing the entire IP packet when
you copy the mbuf? Is the more fragments flag set in the IP header?
Wireshark tells me that the packet is broken into two pieces. This
particular packet is an HTTP request. I need to find the "Host:" part
near the end and it doesn't show up in the first half of the packet.
Is the more fragments flag in the ip_off field?
