I think this number comes up because NICs tend to have power-of-2
sized memory, and 2k is (was?) a common number for cheap NICs. So a
full-sized packet and a fragment that fit into the 2k is less of a
problem than a more-than-2k-total burst of fragments, and perhaps the
fragmentation isn't much of a problem in the local network situation.
