Re: handle packets by libipq

[Scott MacKay <scottmackay@yahoo.com>]

You re-inject using ipq_set_verdict.  Moving a packet
from ipv4 to ipv6...dunno.  ipv4 and ipv6 use 2
different interfaces ( ipq_create_handle(0, PF_INET)
vs  ipq_create_handle(0, PF_INET6) and 2 different
ip_queues (ip_queue.o, ip6_queue.o), so not sure if
you can.  More likely would need to drop from 1 and
regenerate on the other, but not sure on that one.
