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 :-)
