2 Linux Driver

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.

This section describes the user space command interfaces provided with the 78Q8430 Linux device

driver. The user space command interfaces include:

• 8430-tool: for the chip features that cannot be addressed by the standard Linux Ethernet command

interfaces.

• ethtool: for standard Linux Ethernet control commands.

• mii-tool: for standard Linux Ethernet control commands.

2.1 8430-tool Application

This section describes the 8430-tool usage. This tool supports many features of the 78Q8430 that are

not covered by ethtool and mii-tool. The 8430-tool application provides support for the following 78Q8430

features:

• BIST execution and reporting.

• ARC definition and control.

• CAM definition and control.

• Firewall support.

• Frame modification and packet control.

• HNR support.

• WOL support for Magic Packet and OnNow.

• PAUSE packet support with user configurable parameters.

• RMON support.

• PHY/MII support (supplemented by ethtool and mii-tool).

• Jumbo packet support up to 8K on Linux.

• MAC reset.

• TCP Offload Engine (TOE) support for ICMP packets.

• Debug support with register access for MAC and PHY.

A summary of the commands and syntax is followed by a detailed description of each command.
