  Modified files:
    sys/net              bpf.c 
  Log:
  Check for a NULL free buffer pointer in BPF before invoking
  bpf_canfreebuf() in order to avoid potentially calling a non-inlinable
  but trivial function in zero-copy buffer mode for every packet
  received when we couldn't free the buffer anyway.
