...and pray tell how is that done ?? What exactly is the eth0 device file ?

Although, top posting is bad, leaving out context is also just as bad (if not 
worse). Please use interleaved posting.

To the OP, you asked:

What exactly do you mean ? If you do not want the association of eth0:X with the 
IP, how else will you refer to the device associated with the IP ? (for instance 
while using the ifconfig, route or iptable commands).

AFAICT[1], RTNETLINK is refers to the netfilter API to manipulate the kernel 
routing tables not any user space tool to assign IP addresses to NICs
