   1 /*
   2  * ddi.c        Implement the Device Driver Interface (DDI) routines.
   3  *              Currently, this is only used by the NET layer of LINUX,
   4  *              but it eventually might move to an upper directory of
   5  *              the system.
   6  *
   7  * Version:     @(#)ddi.c       1.0.5   04/22/93
   8  *
   9  * Author:      Fred N. van Kempen, <waltje@uwalt.nl.mugnet.org>
  10  *
  11  *
  12  *      For the moment I'm classifying DDI as 'dead'. However if/when Fred
  13  *      produces a masterpiece of design DDI may get resurrected. With the
  14  *      current kernel as modules work by Peter MacDonald they might be
  15  *      redundant anyway. Thus I've removed all but the protocol initialise.
  16  *
  17  *      We will end up with protocol initialisers and socket family initialisers.
