find a libpcap using CONFIG_PACKET_MMAP, and you will probably forget about drops IMHO
if you do find it, please let me now
I'm currently using pandora's monitor modified libpcap.... GREAT
I think that Linux is the only OS that provides user space buffers to packet capture... am I wrong?
Maybe this is an offtopic on this mailing list... ...so this is my first and last mail about it here.
