from my point of view this is not a good idea, because libpcap is for
Ethernet traffic. But ask the libpcap guys what they think about it.

This should be the way to go, because live capturing is not always what
you want. However ethereal can read from stdin and we can modifiy
hcidump to output the raw packages to stdout.
