Is your ethernet device really named "if" not "eth0". You must be
using nameif or something to rename it.

Perhaps the name isn't what you expect.  Look at things like: 
	ifconfig -a
and
	ls /sys/class/net

What ever you are using to assign the name "if" to the device is (which defaults to eth0)
probably got confused
