This file describes the Linux* Base Driver for the Intel(R) PRO/1000 Family
-of Adapters, version 4.3.x. This driver includes support for
+of Adapters, version 4.4.x. This driver includes support for
Itanium(TM)-based systems.
This release version includes the following:
default in supporting kernels. It is not supported on the Intel(R)
PRO/1000 Gigabit Server Adapter.
-New features include:
+Features include:
- Support for the 82545 and 82546-based adapters listed below
RxIntDelay
Valid Range: 0-65535 (0=off)
-Default Value: 0 (82542, 82543, and 82544-based adapters)
- 128 (82540, 82545, and 82546-based adapters)
+Default Value: 0
This value delays the generation of receive interrupts in units of 1.024
microseconds. Receive interrupt reduction can improve CPU efficiency if
properly tuned for specific network traffic. Increasing this value adds
may be set too high, causing the driver to run out of available receive
descriptors.
- CAUTION: When setting RxIntDelay to a value other than 0, adapters based
- on the Intel 82543 and 82544 LAN controllers may hang (stop
- transmitting) under certain network conditions. If this occurs a
- message is logged in the system event log. In addition, the
- controller is automatically reset, restoring the network
- connection. To eliminate the potential for the hang ensure that
- RxIntDelay is set to 0.
