Add hardware timestamping support
pcap provides a pcap_set_tstamp_type function, which can be used to request hardware timestamps from a supporting kernel. This patch adds support for aforementioned function as well as two new command line options to dumpcap, wireshark and tshark: --list-time-stamp-types List time stamp types supported for the interface --time-stamp-type <type> Change the interface's timestamp method Name choice mimics those used by tcpdump(1), which already supports this feature. However, unlike tcpdump, we provide both options unconditionally. If Wireshark was configured without pcap_set_tstamp_type being available, --list-time-stamp-types reports an empty list.
