I'm trying to get tcpdump work with DAG interface. I installed the

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?
The problem is that the libpcap being used by tcpdump isn't DAG-
enabled for some reason; it's trying to attach to adapter "dag0" using
BPF, not using the DAG code.
Is HAVE_DAG_API set in config.h in the source directory for the
libpcap you built? If so, what does "ldd" print when you run it on
the tcpdump you built?

This is the tcpdump-workers list.
