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:
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

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 obtain
~# mii-tool
