nanosecond timestamp precision and packet trailers in pcapy.dumper about pcapy HOT 2 OPEN

update: i ran a tcpdump capture with and without -K. both displayed the trailer, so -K makes no difference.

deep in the documentation for dpkt i found an example that had an additional argument "nano" in their Writer function. replacing the pcapy dumper with the dpkt writer resolves my issue with the timestamps in the header being reported only in microseconds. What this tells me, is that the reading of the binary data with the pcapy.open_live() does not need to be looked at; it is only the dumper that needs an extra argument.

example working function in dpkt:

dumper = dpkt.pcap.Writer(open(path + filename)+'.pcap', 'wb+'),nano=True)
dumper.writepkt(ethernet)
