- When feed-forward clock support is compiled in, change the BPF header to
  contain both a regular timestamp obtained from the system clock and the
  current feed-forward ffcounter value. This enables new possibilities including
  comparison of timekeeping performance and timestamp correction during post
  processing.

- Add the net.bpf.ffclock_tstamp sysctl to provide a choice between timestamping
  packets using the feedback or feed-forward system clock.

Committed on behalf of Julien Ridoux and Darryl Veitch from the University of
Melbourne, Australia, as part of the FreeBSD Foundation funded "Feed-Forward
Clock Synchronization Algorithms" project.
