This document describes the usage and errata of the 3Com "Vortex" device

driver for Linux.

This driver supports the following hardware:

        3c590, 3c592, 3c595, 3c597

When loaded as a module the following variables may be set:

 name    type   description

 debug   int    The debug message level, 0 (no messages) to 6 (wordy).

 options int[]  The media type override and card operation settings

                (See list below.)

An example of loading the vortex module is

        insmod 3c59x.o debug=1 options=0,,12

This sets the debug message level to minimal messages, sets the first card to

the 10baseT transceiver, the second to the EEPROM-set transceiver, and the

third card to operate in full-duplex mode using its 100baseTx transceiver.

(Note: card ordering is set by the PCI BIOS.)

Possible media type settings

        1       10Mbs AUI

        2       undefined

        3       10base2 (BNC)

        4       100base-TX

        5       100base-FX

        6       MII (not yet available)

        7       

        8       Full-duplex bit

                8 10baseT full-duplex

                12 100baseTx full-duplex

        16      Bus-master enable bit (experimental use only!)
