New Revision: 351479
URL: https://svnweb.freebsd.org/changeset/base/351479

Log:
  MFC r350881:
  
  Calculate the number interface array elements using the new FR_NUM macro
  instead of the hard-coded value of 4. This is a precursor to increasing
  the number of interfaces speficied in "on {interface, ..., interface}".
  Note that though this feature is coded in ipf_y.y, it is partially
  supported in the ipfilter kld, meaning it does not work yet (and is yet
  to be documented in ipf.5 too).
