I had a look at that patch and while it's very neat and clean,
I'd rather not be free'ing the mbuf in so many places, so I
jiggled around with the code a little.
Did you have any sort of test rig to verify this? If so,
can you please try the patch below if you think it also fixes
the problem?
Thanks,
Darren
