tcpdump problem with DAG card

["lei wei" <weilei1983 () gmail com>]

Hello,

I'm trying to get tcpdump work with DAG interface. I installed the
dag-enabled libpcap0.9.8 and tcpdump3.9.8 on a FreeBSD5.4 system. When I
typed "tcpdump -i dag0", it gives me the error "tcpdump: BIOCSETIF: dag0:
Device not configured". Could anyone give me any hint on what the problem
is?

Thank you.
