Alfredo Since .ts is the only timestamp in the ZC api, and the igb timestamp is a 20bit value, if you set the ts field to the hardware timestamp then there is no record of the actual date/time of arrival of a packet. Is this correct or am I missing something?
Using DNA you have a function pfring_set_device_clock which was useful. Setting the clock to 0 at the start of a measurement meant I didnt have to deal with clock wrapping. Is there anyway to clear the clock using ZC?
