One of my customers comments that he doesn't care about jumbograms of
9K or 4K - what he really wants is to be sure the networks support
MTUs of at least 1600-1700 bytes, so that various combinations of
IPSEC, UDP-padding, PPPoE, etc. don't break the real 1500-byte packets
underneath.

nice to have smart customers!
