Generally, an interface is configured at network startup time,
and tools such as 'ifconfig' query the driver interface for
information.  How the information is stored and presented to
ifconfig is distribution-dependent-- e.g., RedHat uses files in
/etc/sysconfig/network-scripts, and data from these files is parsed and
used in the network startup script in /etc/rc.d/init.d (and links to
the startup level directories).

You know, it *is* Open Source--just grab a copy of 'ifconfig' and take a look
at it.
