[Bro] Huge number of "Bad_IP_Checksum" warnings on FreeBSD8 captured traffic.

I have not counted but nearly every packet captured through tcpdump on
FreeBSD 8 i386 when analyzed by Bro
generates a "Bad IP Checksum" weird warning.This only happens to me on
FreeBSD and I run a lot of systems:
Windows7,MacOSX,Linuxes,Solaris...
So,how can I avoid this and filter only the normal warnings,because it seems
very related to FreeBSD 8 network
interfaces,tcpdump on FreeBSD 8 ,etc.


      Thanks.
