bpf or pcap :excluding locally generated packets

["kifah Abbad" <kifah () prz tu-berlin de>]

Hi guys,

in freebsd i noticed a feature of bpf, that lets one exlude locally generated
packets from a sniffing session using 

BIOCSSEESENT ioctl 

or setting bd_seesent = 0

I noticed that on openbsd there is nothing like that (at least not mentioned in
man bpf)

Is there a way when capturing from a device? to make pcap, or whatever used for
capturing exlude locally injected packets?(ignore them)...otherwise i would be
running in a loop.
