Method and Apparatus to provide a Generic Menu Handler (GMH) for Network

Adapters

A method to provide Generic Menu Handler (GMH) for network adapters with in a data processing system is being disclosed. The GMH will be setting various parameters such as speed and duplex for a given network adapter . In the proposed disclosure by using the new GMH, system firmware would be independent in regards to introducing a new adapter to a system. Every adapter will be served in the same manner. Not only the time for additional coding and testing would be saved per adapter, but also additional coding and testing will be saved per platform. The new GMH will be more user-friendly. The existing menus require multiple display menus for speed and duplex in order to set the adapter's parameters, whereas GMH will need only one menu.

At the probe time, during initial program load (IPL), the Open Firmware (OF) adapter driver for a particular adapter will be executed. As part of execution, variety of properties are created in the device's node under device tree. Among those properties there is a property called supported-network-types. This property is defined in Open Firmware Recommended Practice - Device Support Extensions version 1.0 by open firmware working group. The property reports all possible types of "networks" the device can support. For example, supported-network-types for a particular adapter could be:

" ethernet,auto,rj45,auto" " ethernet,10,rj45,half" " ethernet,10,rj45,full" " ethernet,...
