  SVN rev 183102 on 2008-09-16 20:32:29Z by csjp
  
  Implement zero-copy bpf(4) buffer or "zbuf" support for libpcap.  A slightly
  different version has been committed upstream in the libpcap vendor branch.
  This will allow people to experiment with zero-copy bpf(4) without requiring
  external patches.
  
  Note to enable this functionality:
  
      sysctl net.bpf.zerocopy_enable=1
  
  By default, libpcap will use the legacy buffering method unless this sysctl
  variable is set to 1.
  
  For the details about zero-copy bpf(4) implementation see svn change r177548.
