Hi,

I have been using libpcap 0.4 which comes packed with
RH6.2. I'll be migrating to libpcap 0.6, soon. The
changelog says that Linux implementation of libpcap
now uses PF_PACKET sockets and the filtering itself is
done in the kernel. So am I correct in assuming that
in 0.4, the filtering in linux was actually done in
userland (even though the timestamping was  done at
the time packet appears on the wire) ? 

And so with the kernel filtering, will applications
running libpcap 0.6  on Linux, perform perceptibly
better (assuming high packet traffic rate, longer
per-packet processing time and a CPU starved linux
6.2, which causes the packet drops currently with
libpcap 0.4) ?

Is there any reason why upgrading to 0.7 may be a
better idea instead ? (The changelog for 0.7 didnt
show anything which my application cares about.)

Thanks for your suggestions,
Joe
