I'm working on an application where (through winpcap) packets are received
and sent. I have created two threads: one will only receive packets, the
other will only send packets. Both threads have their own handle to the same
Because the sender never receives packets, it never calls pcap_next (or one
of the other packet retrieving functions). Only pcap_sendpacket() is used.
Which filter should I set to let the driver know about this? I was thinking
of something a filter like "len <= 1". Will this work? Sending packets
should not be limited by the filter in any way.
