thought twice on this topic.
for the sake of non-optimal implementation (such as embedded devices)
i may want to permit packets > 1200 bytes.
but embedded devices are ok to choose outgoing link MTU be 1280, i.e.
never generate fragmented packets - you need some control over TCP MSS,
need some tricky dance in IPv6 TCP IPsec.
KAME IPsec/TCP MSS handling supports such usage, OpenBSD IPsec does not.
