Hi Alfredo: I just want to describe my use case. I have a machine with 16 Intel 10G interfaces, basically serving as a pcap recorder. I can record alot of packets but I'm interested in having better timestamp resolution on the packets, right now they are at millisecond and micro-second level. I was wondering if hardware timestamping can be used for this scenario. The only information I have thus far in addition to linux ptp (which i'm not sure fits my use case) is this white paper about high resolution packet capture. http://icai.ektf.hu/pdf/ICAI2010-vol2-pp237-245.pdf
