- If the misc/pf-ring-load-balancing script is loaded, the correct environment variables will be set to enable automatic flow based load balancing used pf_ring if Bro is built against the pf_ring libpcap wrapper. Loading the script on non-Linux OSs or when Bro isn't linked against the correct libpcap has no known side effects since the script just sets environment variables. - Added a BiF named setenv for setting environment variables.
