avg_off: the average observed offset of the transport header in packets. This should converge to 14 on Ethernet.
max/min_tran: tracking the transport-layer size of packets; max_tran = max_len-avg_off if GSO is off.
max/min_adj: tracking the overhead-adjusted size of packets; these should be the adjusted sizes of the corresponding transport-layer sizes, so can be used to check the calculations.
It's probably feasible to lay these out better in the output, so they take up fewer lines on screen.
