Great to know. libpcap is leveraged for filtering purposes ('filter'
keyword in pre_tag_map and 'aggregate_filter') and this is a known
limitation (perhaps the most annoying) of libpcap-based filters. It's
some time i'm thinking would be good to find viable (ie. also more
efficient) alternatives to that.

Cheers,
Paolo
