The case defines a new device tree property 'max-frame-size' for the NIU port devices, and updates the binding accordingly. The interface can be released in a micro/minor version of the firmware. The case is set to expire on 9/3/2008. Steve http://sac.eng.sun.com/Archives/CaseLog/arc/FWARC/2008/552/onepager.txt Copyright 2008 Sun Microsystems 1. Introduction 1.1. New Max Frame Size Property For NIU Hybrid IO 1.2. Name of Document Author/Supplier: Michael Speer 1.3. Date of This Document: 08/26/2008 1.4. Email Aliases: 1.5.2. Responsible Engineer: Michael.Speer@Sun.COM, 1.5.3. Interest List: Raghuram.Kothakota@Sun.COM, Sriharsha.Basavapatna@Sun.COM 2. Project Summary 2.1. Project Description: This project updates the NIU device tree binding to add a new property which will allow a guest domain hybyrid NIU (nxge) device to enable jumbo frame operation. 3. Technical Description: 3.1. Details: 3.1.1 Introduction: The hybrid mode nxge device can be dynamically assigned to a guest domain. It consists of a Virtual Region and a set of RX and TX channels. It is plugged directly into the vnet device that is operating in the hybrid I/O mode. The traditional interfaces GLDv3 layer to configure, operate, and move data between the vnet and the hybrid nxge device are not utilized. Instead, the interface in [1] is utilized. To configure the hybrid NIU device properly for jumbo frames, it must be done at driver attach time. Additionally, when the hybrid NIU's device is created and graphted onto the Solaris device tree, the vnet's DDS[2] service knows whether to add to the device node the property to configure jummbo frame operation or not. 3.1.2 Problem Statement: The nxge driver configures operational parameters such as jumbo frames today as a device property from the device's .conf file or via the Brussels m_setop/m_getop interface. In the guest domain none of these interfaces are available to the guest domain Hybrid NIU (nxge) device driver. Hence, a solution is needed to enable proper jumbo frame operation that does not require large changes and is portable to Solaris 10 Update as well (some interfaces e.g. Brussels is not available in Solaris 10 Update). 3.1.3 Proposal: In order to support jumbo frames in the guest domain via the Hybrid mode nxge device, the device needs the information about the maxframesize that is currently programmed in the MAC. To provide this information to the hybrid mode nxge device node, we are proposing an optional property named max-frame-size that reflects the currently programmed value. At the time the vnet's DDS creates the device node for nxge before it is attached in the guest domain, it will add this property to the device node. Then, the driver will attach and configure properly. 3.2.
