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
       0       10baseT
       1       10Mbs AUI
       2       undefined
       3       10base2 (BNC)
       4       100base-TX
       5       100base-FX
       6       MII (not yet available)
       7       <Use default setting>

       8       Full-duplex bit
               8 10baseT full-duplex
               12 100baseTx full-duplex
       16      Bus-master enable bit (experimental use only!)
