LLIPort Valid Range:0-65535 (0=off) Default Value:0 LLI is configured with the LLIPort command-line parameter, which specifies which TCP port should generate Low Latency Interrupts. See the section "InterruptThrottleRate" in README. Inother words, minimizing the receive and/or transmit absolute delays does not force the controller to generate more interrupts than what the Interrupt Throttle Rate allows. NOTE: InterruptThrottleRate takes precedence over the TxAbsIntDelay and RxAbsIntDelay parameters. Un-supported Adapters: InterruptThrottleRate is NOT supported by 82542, 82543 or 82544-based adapters. If this is the case, change this value to 0. However this setting may result in slower overall transfer speeds if network traffic consists mostly of small packets. The default setting is configured to optimize interrupts for bulk throughput while keeping CPU utilization low. Dynamic mode uses a heuristic algorithm to adjust InterruptThrottleRate based on the current traffic load. InterruptThrottleRate is another setting used in interrupt moderation. For example: modprobe igb InterruptThrottleRate=16000,16000 InterruptThrottleRate Valid Range: 0,1,3,100-100000 (0=off, 1=dynamic, 3=dynamic conservative) Default Value: 3This represents the maximum number of interrupts per second the controller generates.
OPTIONSThe following optional parameters are used by entering them on the command line with the modprobe command. This driver supports 2.5 Gbps operating speed on 2500BASE-KX only for I354-based network connections. All hardware requirements listed apply to use with Linux. For questions related to hardware requirements, refer to the documentation supplied with your Intel adapter. Intel is not supplying patches against the kernel source toallow for static linking of the driver. This driver is only supported as a loadable module at this time. This driver includes support for Intel(R) Itanium(R)2-based systems. SYNOPSISmodprobe igb DESCRIPTIONThis driver is intended for 2.4.x and 2.6.x kernels. To determine whether your driver type requires that you store information under specific registry keys, see the sections of this documentation that discuss your driver's device type by using the table of contents.NAMEigb -This file describes the Linux* Base Driver for the Gigabit Family of Adapters. Your driver's INF file can contain INF AddReg directives that set registry values under the hardware key using INF DDInstall.HW sections. Your driver can call WdfFdoInitOpenRegistryKey and WdfDeviceOpenRegistryKey to open a device's hardware key. Settings related to the hardware (such as interrupt settings) can be stored here by drivers. When a driver stack informs the Plug and Play (PnP) manager that a device is connected to the system, the PnP manager creates a hardware key for the device.

Your driver's INF file can contain INF AddReg directives that set registry values under the software key using INF DDInstall sections. Your driver can call WdfFdoInitOpenRegistryKey and WdfDeviceOpenRegistryKey to open a device's software key. The system stores information about each driver under its software key. Subsequently, the driver can obtain the path by calling WdfDriverGetRegistryPath.Ī driver's software key is also called its driver key.
Your driver must pass this path to WdfDriverCreate. When the system calls your driver's DriverEntry routine, it passes the driver a path to the driver's key in the appropriate Services tree. The subkey for the driver always uses the driver's service name, even if the driver binary's file name differs from the service name. For User-Mode Driver Framework (UMDF) drivers, this key is located in the HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WUDF\Services tree, under the driver's service name. For Kernel-Mode Driver Framework (KMDF) drivers, this key is located in the appropriate Services tree for the driver. The driver's Parameters key can contain configuration information for your driver and can be accessed by calling WdfDriverOpenParametersRegistryKey. Your driver might access the following registry keys:
#INTEL I210 DRIVER PARAMETERS DRIVERS#
Drivers typically use a set of system-defined registry keys to store or access driver-specific or device-specific information.
