** init() Initialize controller
**
** int init(int netno, char *params);
**
** PARAMETERS:
** (in) netno Index into nets[] array
** (in) params Pointer to parameter list
**
** RETURNS:
** 0 Initialization successful
** NE_PARAM Bad parameters
**
** DESCRIPTION:
** Configure and start up the ethernet controller. Process the
** user-level text parameters and store the values into the net
** table. Read the address from the Ethernet board and set up the
** board. Store the interrupt address and enable the interrupt.
**
** USAGE/COMMENTS:
** Called indirectly using pointer defined in PTABLE
**
** * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
**
** MODIFICATION HISTORY:
**
** 22-JUN-2000 BTS Only enable MC when MC support is included
** 19-JAN-1999 SCD Add function header
