/* smc-ultra.c: A SMC Ultra ethernet driver for linux. */
/*
	This is a driver for the SMC Ultra and SMC EtherEZ ISA ethercards.

	Written 1993-1998 by Donald Becker.

	Copyright 1993 United States Government as represented by the
	Director, National Security Agency.

	of the GNU General Public License, incorporated herein by reference.

	This driver uses the cards in the 8390-compatible mode.
	Most of the run-time complexity is handled by the generic code in
	8390.c.  The code in this file is responsible for

		ultra_probe()	 	Detecting and initializing the card.
		ultra_probe1()
		ultra_probe_isapnp()

		ultra_open()		The card-specific details of starting, stopping
		ultra_reset_8390()	and resetting the 8390 NIC core.
		ultra_close()

		ultra_block_input()		Routines for reading and writing blocks of
		ultra_block_output()	packet buffer memory.
		ultra_pio_input()
		ultra_pio_output()

	This driver enables the shared memory only when doing the actual data
	transfers to avoid a bug in early version of the card that corrupted
	data transferred by a AHA1542.

	This driver now supports the programmed-I/O (PIO) data transfer mode of
	the EtherEZ. It does not use the non-8390-compatible "Altego" mode.
	That support (if available) is in smc-ez.c.

	Changelog:

	Paul Gortmaker	: multiple card support for module users.
	Donald Becker	: 4/17/96 PIO support, minor potential problems avoided.
	Donald Becker	: 6/6/96 correctly set auto-wrap bit.
	Alexander Sotirov : 1/20/01 Added support for ISAPnP cards

	Note about the ISA PnP support:

	This driver can not autoprobe for more than one SMC EtherEZ PnP card.
	You have to configure the second card manually through the /proc/isapnp
	interface and then load the module with an explicit io=0x___ option.

	17
	18	This driver uses the cards in the 8390-compatible mode.
	19	Most of the run-time complexity is handled by the generic code in
	20	8390.c. The code in this file is responsible for
	21
	22	ultra_probe() Detecting and initializing the card.
	23	ultra_probe1()
	24	ultra_probe_isapnp()
	25
	26	ultra_open() The card-specific details of starting, stopping
	27	ultra_reset_8390() and resetting the 8390 NIC core.
	28	ultra_close()
	29
	30	ultra_block_input() Routines for reading and writing blocks of
	31	ultra_block_output() packet buffer memory.
	32	ultra_pio_input()
	33	ultra_pio_output()
	34
	35	This driver enables the shared memory only when doing the actual data
	36	transfers to avoid a bug in early version of the card that corrupted
	37	data transferred by a AHA1542.
	38
	39	This driver now supports the programmed-I/O (PIO) data transfer mode of
	40	the EtherEZ. It does not use the non-8390-compatible "Altego" mode.
	41	That support (if available) is in smc-ez.c.
	42
	43	Changelog:
	44
	45	Paul Gortmaker : multiple card support for module users.
	46	Donald Becker : 4/17/96 PIO support, minor potential problems avoided.
	47	Donald Becker : 6/6/96 correctly set auto-wrap bit.
	48	Alexander Sotirov : 1/20/01 Added support for ISAPnP cards
	49
	50	Note about the ISA PnP support:
	51
	52	This driver can not autoprobe for more than one SMC EtherEZ PnP card.
	53	You have to configure the second card manually through the /proc/isapnp
	54	interface and then load the module with an explicit io=0x___ option.
