Configuring the Driver on Different Distributions

  Configuring a network driver to load properly when the system is started is

Multiple Interfaces on Same Ethernet Broadcast Network

  Due to the default ARP behavior on Linux, it is not possible to have

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

(non-partitioned switch) behave as expected.  All Ethernet interfaces

will respond to IP traffic for any IP address assigned to the system.

This results in unbalanced receive traffic.
