Comments, suggestions, spelling nitpicks? 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 :-) Which I should have done first :-) If timestamps are off it's still about 1 1/3 bytes per frame more efficient. If they are on (default on linux costing 12 bytes) the smaller mtu is about 1 byte per frame less efficient.
