ok but:
o They should at least be aware of that unexpected behavior because
this will break AH protected TCP-connections in the _default_ case
o mangling of such packet is equivalent to a drop for them, except
that it will be a mess to debug at the other side (packet will flow,
but will be invalid)
anyway, who uses AH ? ;)
