I know that ifconfig and iwconfig can actually read and write to this
structure in order to control and query the network devices. So, far, it
looks like it will take a few days to slug through the ifconfig or iwconfig
sources. By the way, the ifconfig sources are in net-tools-1.60.tar.bz2 in
case anyone else is interested in how this works.
I did get to ifconfig.c and its cousin, interface.c in those source last
night, but I couldnt quite come to a grok yet.
In any case, back to Rubini's book.
