Looks good - one picky point - if your overhead means only 4 bytes
padding at default mtu are needed, then reducing mtu to be "optimal" for
IP and above levels may be less efficient from the point of view of the
tcp data because of the reduced payload vs fixed overheads.
I haven't done the maths on that :-)
Andy.
