  SVN rev 200029 on 2009-12-02 15:20:31Z by luigi
  
  small changes for portability and diff reduction wrt/ FreeBSD 7.
  No functional differences.
  
  - use the div64() macro to wrap 64 bit divisions
    (which almost always are 64 / 32 bits) so they are easier
    to handle with compilers or OS that do not have native
    support for 64bit divisions;
  
  - use a local variable for p_numbytes even if not strictly
    necessary on HEAD, as it reduces diffs with FreeBSD7
  
  - in dummynet_send() check that a tag is present before
    dereferencing the pointer.
  
  - add a couple of blank lines for readability near the end of a function
  
  MFC after:      3 days
