From 5255c03037737fc58839e519adf6e595e0f778ef Mon Sep 17 00:00:00 2001 From: Vincent Perot Date: Tue, 3 Jun 2014 17:37:09 -0400 Subject: [PATCH] tmf: Initial commit of Pcap Parser This commit is the first step toward adding pcap-reading abilities to TMF. It only adds the parser, and as such it is completely independent from TMF. The parser supports four protocols (Ethernet, IPv4, TCP, UDP) and both microsecond and nanosecond pcap files.
