Doc Text:	tcpdump supports -J, -j, and --time-stamp-precision options As kernel, glibc, and libpcap now provide APIs to obtain nanosecond resolutions timestamps, tcpdump has been updated to leverage this functionality. Users can now query which timestamp sources are available (-J), set a specific timestamp source (-j), and request timestamps with a specified resolution (--time-stamp-precision).	Story Points:	---

Description of problem:

Need tcpdump to support new libpcap nanosecond timestamping

libpcap now supports nanonsecond timestamps via BZ below

https://bugzilla.redhat.com/show_bug.cgi?id=916749 

At [1] you can find tcpdump built against libpcap containing high precision timestamp patches. Please note -P switch and also switches -j/-J.
