    share/man/man4       bpf.4 
    sys/net              bpf.c bpf.h bpfdesc.h 
  Log:
  Introduce a new bd_seesent flag to the BPF descriptor, indicating whether or
  not the current BPF device should report locally generated packets or not.
  This allows sniffing applications to see only packets that are not generated
  locally, which can be useful for debugging bridging problems, or other
  situations where MAC addresses are not sufficient to identify locally
  sourced packets.  Default to true for this flag, so as to provide existing
  behavior by default.
  
  Introduce two new ioctls, BIOCGSEESENT and BIOCSSEESENT, which may be used
  to manipulate this flag from userland, given appropriate privilege.
  
  Modify bpf.4 to document these two new ioctl arguments.
