+In This Release
+===============
+
+This file describes the Linux* Base Driver for the Intel(R) PRO/100 Family of
+Adapters, version 2.0.x.  This driver includes support for Itanium(TM)-based 
+systems.
+
+New for this release:
+
+   - Additional ethtool functionality, including link status test and EEPROM 
+     read/write. A third-party application can use the ethtool interface to 
+     get and set driver parameters.
+
+   - Support for Zero copy on 82550-based adapters. This feature provides 
+     faster data throughput and significant CPU usage improvement in systems 
+     that use the relevant system call (sendfile(2)).
+
+   - Support for large MTU-enabling interface (1504 bytes) with kernel's 
+     VLAN module
+
+   - Support for polling on RX
+
+   - Support for Wake On LAN* on 82550 and 82559-based adapters
+
+
+Supported Adapters
+==================
+
+The following Intel network adapters are compatible with the drivers 
+in this release:

+
+To verify that your adapter is supported, find the board ID number on the 
+adapter. Look for a label that has a barcode and a number in the format 
+123456-001 (six digits hyphen three digits). Match this to the list of 
+numbers above.
+
+For more information on how to identify your adapter, go to the Adapter & 
+Driver ID Guide at:
+
+  http://support.intel.com/support/network/adapter/pro100/21397.htm
+
+For the latest Intel PRO/100 network driver for Linux, see:
+
+  http://appsr.intel.com/scripts-df/support_intel.asp
+
+
+Command Line Parameters
+=======================
+
+The following parameters are used by entering them on the command line with 
+the modprobe or insmod command. For example, with two Intel PRO/100 PCI 
+adapters, entering:
+	
+     modprobe e100 TxDescriptors=32,128
+
+loads the e100 driver with 32 TX resources for the first adapter and 128 TX 
+resources for the second adapter. This configuration favors the second 
+adapter. The driver supports up to 16 network adapters concurrently.
+
+NOTE: Giving any command line option the value "-1" causes the driver to use 
+      the appropriate default value for that option, as if no value was 
+      specified.
+
+
+BundleMax
+Valid Range: 0x1-0xFFFF
+Default Value: 6
+   This parameter holds the maximum number of packets in a bundle. Suggested 
+   values range from 2 to 10. See "CPU Cycle Saver."
+
+BundleSmallFr
+Valid Range: 0-1 (0=off, 1=on)
+Default Value: 0
+   The value 1 (on) causes small packets (less than 128 bytes) to be bundled. 
+   See "CPU Cycle Saver."
+
+e100_speed_duplex
+Valid Range: 0-4 (1=10half;2=10full;3=100half;4=100full)
+Default Value: 0
+   The default value of 0 is set to auto-negotiate if the link partner is set
+   to auto-negotiate. If the link partner is forced, e100_speed_duplex 
+   defaults to half-duplex. 
+   Example usage: insmod e100.o e100_speed_duplex=4,4 (for two adapters)
+
+flow_control
+Valid Range: 0-1 (0=off, 1=on)
+Default Value: 0
+   This parameter controls the automatic generation(Tx) and response(Rx) to 
+   Ethernet PAUSE frames. flow_control should NOT be set to 1 when the e100 
+   adapter is connected to an interface that does not support Ethernet PAUSE 
+   frames and when the e100_speed_duplex parameter is NOT set to zero. 
+
+IntDelay
+Valid Range: 0-0xFFFF (0=off)
+Default Value: 1536
+   This parameter holds the number of time units (in adapter terminology)
+   until the adapter generates an interrupt. The recommended value for 
+   IntDelay is 0x600 (upon initialization). Suggested values range from 
+   0x200h to 0x800. See "CPU Cycle Saver."
+
+IFS
+Valid Range: 0-1 (0=off, 1=on)
+Default Value: 1
+  Inter Frame Spacing (IFS) aims to reduce the number of Ethernet frame
+  collisions by altering the time between frame transmissions. When IFS is 
+  enabled the driver tries to find an optimal IFS value. However, some 
+  switches function better when IFS is disabled.
+
+PollingMaxWork
+Valid Range: 1-1024 (max number of RxDescriptors)
+Default Value: Specified number of RxDescriptors
+  This value specifies the maximum number of receive packets that are 
+  processed on a single polling call. This parameter is invalid if 
+  RxCongestionControl is set to 0.
+
+RxCongestionControl
+Valid Range: 0-1 (0=off, 1=on)
+Default Value: 1
+  1 enables polling mode. When the link is congested, the driver can decide 
+  to handle received packets by polling them, instead of waiting until 
+  interrupts occur.
+
+RxDescriptors
+Valid Range: 8-1024
+Default Value: 64
+   This parameter defines the number of receive descriptors allocated by 
+   the driver. Increasing this value allows the driver to buffer more 
+   incoming packets before the driver is required to service an interrupt. 
+   The maximum value for Itanium-based systems is 64.
+
+TxDescriptors
+Valid Range: 19-1024
+Default Value: 64
+   This value is the number of transmit descriptors allocated by the driver. 
+   Increasing this value allows the protocol stack to queue more transmits at
+   the driver level. The maximum value for Itanium-based systems is 64.
+
+ucode (not available for 82557-based adapters)
+Valid Range: 0-1 (0=off, 1=on)
+Default Value: 0 for 82558-based adapters
+               1 for 82559(and higher)-based adapters
+   On uploads the micro code to the adapter, which enables CPU Cycle Saver. 
+   See the section "CPU Cycle Saver" below.
+   Example usage: insmod e100.o ucode=0  (does not reduce CPU usage)
+
+XsumRX
+Valid Range: 0-1 (0=off, 1=on)
+Default Value: 1
+   On allows Rx checksum offloading for TCP/UDP packets. Requires that the 
+   hardware support this feature.
+
+
+CPU Cycle Saver
+================
+
+CPU Cycle Saver reduces CPU utilization by reducing the number of interrupts 
+that the adapter generates.
+
+When CPU Cycle Saver is turned off, the adapter generates one interrupt for 
+every frame that is received. This means that the operating system stops what
+it is doing and switches to the network driver in order to process the 
+receive.
+
+When CPU Cycle Saver is on, the adapter does not generate an interrupt for 
+every frame it receives. Instead, it waits until it receives several frames 
+before generating an interrupt. This reduces the amount of time spent 
+switching to and from the driver. 
+
+CPU Cycle Saver consists of these arguments: IntDelay, BundleMax and 
+BundleSmallFr. When IntDelay is increased, the adapter waits longer for 
+frames to arrive before generating the interrupt. By increasing BundleMax, 
+the network adapter waits for the number of frames specified to arrive before 
+generating the interrupt. When BundleSmallFr is disabled, the adapter does 
+not bundle packets that are smaller than 128 bytes. Such small packets are 
+often, but not always, control packets that are better served immediately.
+
+For most users, it is recommended that CPU Cycle Saver be used with the 
+default values specified in the Command Line Parameters section. However, in 
+some cases, performance problems may occur with CPU Cycle Saver. If such 
+problems are observed, we recommend turning off this feature by setting 
+ucode=0.
