I want to capture some traffic with tcpdump. After i run the commnad i
see an greatly number of packets dropped by kernel. I flush all ipfw
rules but nothing.

[root at freebsd #] tcpdump -i fxp0 > out
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on fxp0, link-type EN10MB (Ethernet), capture size 96 bytes
packets captured
5099 packets received by filter
4342 packets dropped by kernel

Where is the problem?
