> Pcap interfaces can have colons in their name, which confuses the new packet source code, as it uses "xxx:" to identify the type of source to use (e.g., "dag0:0" isn't handed over to pcap; instead Bro looks for a plugin "dag0" to handle the interface "0".)
> As a work-around, it should work to use "-i pcap:dag:0".
> Possible fixes:
>   - we use a different prefix separator (e.g., "-i netmap!em3")
>   - fallback to pcap if prefix not known.
>   - make the work around the solution (i.e., if in doubt, specify pcap explicitly)
> Reported by John Donaldson.
