Follow-up Comment #1, task #6861 (project lwip):

I have a patch against lwIP 1.1 to allow ip_frag to either use a static
buffer (like the current implementation) or create a sequence of PBUF_REFs
pointing into the payload of the original buffer.

I'll check if I'm allowed to post it.

Note that if you allow reassembled packets to be given as a chain, care (or
at least a config option) would be needed to prevent running out of pool
pbufs and locking the stack (because they were sitting on a chain waiting for
the last bits to be reassembled).
