Would be very helpful if this PR can include a package-info.java file to
describe this work. For example, what is pcap? Links to good sources? What
features of Drill does it use (push-downs)? Etc.

> Project: Apache Drill
> Issue Type: New Feature
> Reporter: Ted Dunning
>
> PCAP files [1] are the de facto standard for storing network capture data. In
> security and protocol applications, it is very common to want to extract
> particular packets from a capture for further analysis.
> At a first level, it is desirable to query and filter by source and
> destination IP and port or by protocol. Beyond that, however, it would be
> very useful to be able to group packets by TCP session and eventually to look
> at packet contents. For now, however, the most critical requirement is that
> we should be able to scan captures at very high speed.
> I previously wrote a (kind of working) proof of concept for a PCAP decoder
> that did lazy deserialization and could traverse hundreds of MB of PCAP data
> per second per core. This compares to roughly 2-3 MB/s for widely available
> Apache-compatible open source PCAP decoders.
> This JIRA covers the integration and extension of that proof of concept as a
> Drill file format.
> Initial work is available at https://github.com/mapr-demos/drill-pcap-format
