Every packet records a timestamp.
I'm not aware of anything in IP routing that requires a timestamp for every packet. To me it sounds like we could rip that out too.

Maybe as a configurable option, since it would make tcpdump less useful. Seems like we could kludge it up so that we used the TSC (or whatever that really fast hardware clock is) to provide some relative stamp that could be converted to a time_val later?
It does seem a bit wasteful to do the gettimeofday when most of the time the result is ignored.
(Or, are there things other than tcpdump that need the gettimeofday stamp?)
