3 Diagnostic Tools

The 78Q8430 10/100 Ethernet MAC/PHY Linux device driver provides extensive configuration support

through its IOCTL interface. The 78Q8430 is a uniquely feature rich ethernet solution. As such, the

standard Linux ethernet configuration applications, ethtool and mii-tool, do not address the majority of the

available features. For this reason, a new configuration application, the 8430-tool, is provided with the

driver to support the chip's feature set. The 8430-tool application uses the Linux standard set of sixteen

user definable networking IOCTLs. The diagnostic procedures utilize the following utilities:

• 8430-tool: for the chip features that can not be addressed by the standard Linux ethernet command

interfaces.

• ethtool: for standard Linux ethernet control commands.

• mii-tool: for standard Linux ethernet MII control commands.

This section contains a summary of the 8430-tool, ethtool and mii-tool commands. Refer to the 78Q8430

Linux Driver ARM Platform User Guide for a detailed description of the 8430-tool commands.

3.1 ethtool Command Syntax

The following syntax summary lists the ethtool version 4 command options supported by the 78Q8430

device driver. ethtool can be obtained from: http://sourceforge.net/projects/gkernel/.

The EEPROM modification command described below requires a code conveyed by the 'magic' operand.

The required code is 8430.

~# ethtool –h Displays command syntax (as shown below)

ethtool version 4

Usage:

ethtool DEVNAME Display standard information about device

ethtool -i|--driver DEVNAME Show driver information

ethtool -e|--eeprom-dump DEVNAME Do an EEPROM dump

[ offset N ]

[ length N ]

ethtool -E|--change-eeprom DEVNAME Change bytes in device EEPROM

[ magic 8430]

[ offset N ]

[ value N ]

3.2 mii-tool Command Syntax

The following syntax summary lists the mii-tool version 4 command options supported by the 78Q8430

device driver. mii-tool can be obtained from: http://www.metux.de/pub/mii-tool/mii-tool-1.9.1.1.tar.bz2.

~# mii-tool

Usage: mii-tool [-VvRrwl] [-A media,... | -F media] [interface ...]

-R, --reset reset MII to poweron state

-F, --force=media force specified media technology

media: 100baseT4, 100baseTx-FD, 100baseTx-HD,

10baseT-FD, 10baseT-HD,

(to advertise both HD and FD) 100baseTx, 10baseT
