I was digging around, trying to understand whether libpcap can get HW
time stamps via the packet_mmap interface, and I found this.

packet_mmap: expose hw packet timestamps to network packet capture utilities
Maybe you could ask Scott for help?
[ It looks to me like that patch is kinda useless, since the user has
no way to tell whether the time stamps are from HW or SW. ]
