[dpdk-dev] [PATCH v2] net/pcap: propagate timestamp from pcap_pkthdr to mbuf

From: Sylvain Rodon <srn at nexatech.fr>
Timestamp is always set in PCAP header, whether it reads a file or
listen on an interface. This information can be important for some
applications and it cannot be obtained otherwise (especially when
reading a PCAP file, where the timestamp is not the current time).
Timestamp here is the number of microseconds since epoch.
