On the NXP LS1028A, PTP over IP, under a bridge, works with netfilter rules.
I have a Marvell 6390 switch which supposedly supports timestamping, but
I never got that to work, not even L2, and never had the time to sit
down with it and figure out what's wrong. I think I saw a discussion
initiated by George McCollister saying the same thing.
