[dpdk-dev] Saving packet timestamp when reading from pcap

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
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.?)
