Hi. It appears the when I send a frame with pcap_inject, and then do a pcap_next, I get back the same frame I just sent. Is there a way to turn this off? There is a BIOCFEEDBACK ioctl on the underlying bpf fd but that does not appear to have any effect. The reason I don't want this behaviour is that GNS3 does not work when connecting to a host via bpf; the router sees its own packets, which breaks things like IPv6 DAD, bridging, etc. Cheers Michiel
