- Fixes a bunch of bugs related to ematches
- Adds support for the nbyte ematch
- Adds a bison/flex parser for ematch expressions, expressions
may look like this:
ip.length > 256 && pattern(ip6.src = 3ffe::/16)
documenation on syntax follows
- adds ematch support to the basic classifier (--ematch EXPR)
