^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) This driver uses the cards in the 8390-compatible mode.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) Most of the run-time complexity is handled by the generic code in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) 8390.c. The code in this file is responsible for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) ultra_probe() Detecting and initializing the card.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) ultra_open() The card-specific details of starting, stopping
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) ultra_reset_8390() and resetting the 8390 NIC core.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) ultra_block_input() Routines for reading and writing blocks of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) ultra_block_output() packet buffer memory.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) This driver enables the shared memory only when doing the actual data
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) transfers to avoid a bug in early version of the card that corrupted
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) data transferred by a AHA1542.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) This driver now supports the programmed-I/O (PIO) data transfer mode of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) the EtherEZ. It does not use the non-8390-compatible "Altego" mode.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) That support (if available) is in smc-ez.c.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 44)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 45) Paul Gortmaker : multiple card support for module users.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 46) Donald Becker : 4/17/96 PIO support, minor potential problems avoided.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 47) Donald Becker : 6/6/96 correctly set auto-wrap bit.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 48) Alexander Sotirov : 1/20/01 Added support for ISAPnP cards
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 49)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 50) Note about the ISA PnP support:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 51)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 52) This driver can not autoprobe for more than one SMC EtherEZ PnP card.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 53) You have to configure the second card manually through the /proc/isapnp
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 54) interface and then load the module with an explicit io=0x___ option.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 498) byte-sequentially to IOPA, with no intervening I/O operations, and the
