- This driver should work with many programmed-I/O 8390-based ethernet
- boards. Currently it supports the NE1000, NE2000, many clones,
- and some Cabletron products.
-
- Changelog:
-
- Paul Gortmaker : use ENISR_RDC to monitor Tx PIO uploads, made
- sanity checks and bad clone support optional.
- Paul Gortmaker : new reset code, reset card after probe at boot.
- Paul Gortmaker : multiple card support for module users.
- Paul Gortmaker : Support for PCI ne2k clones, similar to lance.c
- Paul Gortmaker : Allow users with bad cards to avoid full probe.
- Paul Gortmaker : PCI probe changes, more PCI cards supported.
- rjohnson@analogic.com : Changed init order so an interrupt will only
- occur after memory is allocated for dev->priv. Deallocated memory
- last in cleanup_modue()
- Richard Guenther : Added support for ISAPnP cards
- Paul Gortmaker : Discontinued PCI support - use ne2k-pci.c instead.
- Hayato Fujiwara : Add m32r support.

- * From the driver distribution kit by Thomas Redelberger:
- *
- * Hardware circuit description (see directory ETHERNEC for schematics)
- *
- * As there is no reset line on the CP, a resistor and a capacitor are
- * used to reset the NE card on power up.
- *
- * Reading from the NE card is done by a read cycle on the CP at address
- * /ROM4 + 512*ISA address as the ISA address lines A0-A4 are connected
- * to CP A9-A13. /ROM4 going low will start the ISA read cycle, enable
- * the ISA bus buffers of the NE card and start decoding of the ISA IO
- * address by the NE card. /ROM4 going high ends the cycle and the
- * processor latches the data.
- *
- * Because the CP is read only writing to the NE card must be done with
- * the trick to read from addresses that stand for the data. Dummy reads
- * at /ROM3 base address + data*2 + ISA address*512 effect this. You
- * might wonder why everything appears to be shifted up one bit. There is
- * no CP "A0" address line. There are the signals /UDS and /LDS instead
- * typical for the 68000 family. The original design which generated an
- * "A0" worked on an ST and an STE but did not on a Falcon.
- *
- * The falling edge of /ROM3 enables the CP address lines A1-A8 onto the
- * data bus and starts the ISA write cycle. The rising edge will end the
- * ISA write cycle and the NE latches the data. The processor will also
- * see and just read this same data but that is harmless.
- * Elmar Hilgart reported that the bus buffer IC shall be an TTL F-type
- * to keep up with the fast cycles on the Falcon.
- *
- * Base addresses:
- * rom4 EQU $00fa0000 ; ROM4 base address
- * rom3 EQU $00fb0000 ; ROM3 base address
- *

- PACKETBUF_MEMSIZE. Reported Cabletron packet buffer locations are:
- E1010 starts at 0x100 and ends at 0x2000.
