The tcp_info struct is now also available under FreeBSD.
Known bugs with this commit:
- The SMSS is printed in the wrong column (CA state instead SMSS)
- The units of the header are wrong since BSD is a byte based stack
Merge remote-tracking branch 'upstream/master'
Header for tcp_info struct in now in bytes for BSD stacks
flowgrind accesses wrong column of header_info if ca_state is not
available (like FreeBSD). As a result the pmtu column wasn't visible.
Merge pull request #4 from alexander-zimmermann/master
