   2  * INET         An implementation of the TCP/IP protocol suite for the LINUX
   3  *              operating system.  INET is implemented using the  BSD Socket
   4  *              interface as the means of communication with the user level.
   5  *
   6  *              Holds initial configuration information for devices.
   7  *
   8  * NOTE:        This file is a nice idea, but its current format does not work
   9  *              well for drivers that support multiple units, like the SLIP
  10  *              driver.  We should actually have only one pointer to a driver
  11  *              here, with the driver knowing how many units it supports.
  12  *              Currently, the SLIP driver abuses the "base_addr" integer
  13  *              field of the 'device' structure to store the unit number...
