Last update on this.

"udelay( 100 + net_random % 300 )" seems to work much better and i have 
not had a single problem getting the link up within 10 seconds of a cold 
or warm-boot, and most often the link comes up directly without any sort 
of delay instead like before when it could hang for 30 seconds before 
getting a link, if you even got a link.
