Yes, I know, but I wonder where, in the code, to poll that register. Do 
I need to provide a task as you do? And netif_set_link_up() has to be 
called only from this task?

I have an implementation... Is the sample code provided by NXP in 
KSDK2.2 (our board is very similar to FRDM K64). They do some strange 
things, but they have provided a task that only deals with receiving the 
data from network. PHY polling is done in an high level (application) 
task that deal with UDP packets.
