Configuring the Driver on Different Distributions
-------------------------------------------------
Configuring a network driver to load properly when the system is started is
distribution dependent. Typically, the configuration process involves adding
an alias line to /etc/modprobe.d/*.conf as well as editing other system
startup scripts and/or configuration files. Many popular Linux
distributions ship with tools to make these changes for you. To learn the
proper way to configure a network device for your system, refer to your
distribution documentation. If during this process you are asked for the
driver or module name, the name for the Linux Base Driver for the Intel
PRO/100 Family of Adapters is e100.

Viewing Link Messages

entering the following on the command line before loading the e100 driver::

Due to the default ARP behavior on Linux, it is not possible to have
one system on two IP networks in the same Ethernet broadcast domain

will respond to IP traffic for any IP address assigned to the system.
This results in unbalanced receive traffic.
