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
A12345-001. Match this to the list of numbers above.

Command Line Parameters
=======================
If the driver is built as a module, the following optional parameters are
used by entering them on the command line with the modprobe or insmod command
using this syntax:
modprobe e100 [<option>=<VAL1>,<VAL2>,...]
insmod e100 [<option>=<VAL1>,<VAL2>,...]
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.
The default value for each parameter is generally the recommended setting,
unless otherwise noted.
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: 1-65535
Default Value: 6
This parameter holds the maximum number of small packets (less than 128
bytes) 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 sets the adapter to auto-negotiate. Other values
set the adapter to forced speed and 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
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: 0-65535 (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 1536 (upon initialization). Suggested values range from
512 to 2048. 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. It is used only at
half duplex.
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
Valid Range: 0-1 (0=off, 1=on)
Default Value: 0 for 82558-based adapters
1 for 82559, 82550, and 82551-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=1
Not available on 82557-based adapters.
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.
Not available on 82557 and 82558-based adapters.
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 small frames (less than 128 bytes)
specified to arrive before generating the interrupt. When BundleSmallFr is
disabled, the adapter does not bundle small packets. Such small packets are
often, but not always, control packets that are better served immediately;
therefore, BundleSmallFr is disabled by default.
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.
