‘Insmod’ Command Line Parameters
The following parameters are used by entering them on the command line with the modprobe or insmod command. For example, with Intel based card model (ex. 5262, 5164, etc.) entering:
insmod dpm [ChipSelector=1] IntrHoldOff=0
loads the dpm driver setting it for Intel chipset and setting the Interrupt Holdoff latency to zero (disabled).
Parameter Name | Valid | Default | Description | |
Range/Settings | ||||
|
|

|
|
|
| |
SetAutoNeg | 0,1 | 1 | This parameter specifies the enabling of auto | |
negotiation. | ||||
| 0,1,2 |
| Defines the direction in which data is allowed to | |
|
| flow. Can be either one or | ||
DuplexMode |
|
| ||
(0=half, 1=full, | 1 | If auto negotiation is enabled, defines modes | ||
| 2=both) |
| advertised. If auto negotiation is disabled sets | |
|
| duplex to this value. | ||
|
|
| ||
PauseFlowEn | 0, 1 | 1 | This parameter enables or disables pause frame | |
flow control (typically enabled). | ||||
|
|
|
| |
|
|
| This value delays the generation of receive | |
|
|
| interrupts in units of 100 microseconds. Receive | |
IntrHoldOff | 0, 1 or 2 (0=off) | 1 | interrupt reduction can improve CPU efficiency if | |
properly tuned for specific network traffic. | ||||
|
|
| Increasing this value adds extra latency to frame | |
|
|
| reception and if set too high could decrease the | |
|
|
| throughput of TCP traffic. | |
|
|
| If auto negotiation id disabled, speed forces the | |
|
|
| line speed to the specified value in megabits per | |
MediaSpeed | 10, 100, 1000 | 1000 | second (Mbps). If auto negotiation is enabled, | |
sets the highest speed advertised. | ||||
|
|
| (adapters using copper connections only) | |
|
|
|
| |
|
|
| This value is the number of transmit and receive | |
NumBufDescs |
|
| descriptors allocated by the driver. Increasing | |
80 - 4096 | 256 | this value allows the driver to queue more | ||
|
|
| transmit and receive buffers. Each descriptor is | |
|
|
| 16 bytes. | |
|
|
|
| |
MaxMtuSize | 1500 | This value is the maximum mtu size supported in | ||
the driver. | ||||
MaxBufferSize | 2048, 4096, | 2048 | Sets the maximum buffer size supported in the | |
8192, 16384 | driver. | |||
AccAllUni | 0, 1 | 0 | Setting this parameter to one instructs the driver |
