To test my program and for some other uses I sometimes use vdev (libpcap pmd) to read data from a pcap file.
Those tests would be a lot easier if the packet timestamp (which is in the cap) was supplied by DPDK, but alas it is not. So I could access it, I placed it in mbuf's userdata for the timebeing. In rte_eth_pcap.c I added this after line 171: mbuf->userdata = (void*) header.ts.tv_sec; Obviously this isn't the prettiest and it lacks the microseconds the struct supplies. Does anyone have any better ideas on how to do it, or is this a feature planned for any future version (seems easy enough to add some more fields to the mbuf struct to accommodate this, and maybe in the future hardware timestamps, etc.?) Thanks, Dor.
