Description

Current suricata is not able to use the hardware timestamping. To enable this, is is enough to call setsockopt with the PACKET_TIMESTAMP option. A good place to put that in is l.1411 in source-af-packet.c.

The possible option value regarding af_packet are:
- SOF_TIMESTAMPING_SYS_HARDWARE
- SOF_TIMESTAMPING_RAW_HARDWARE

(value define in linux/net_tstamp.h)
