The wiki lists major changes. I see nothing that indicates anything 

Is this your BSP and driver or is this a standard BSP in the source tree ?

If it is your driver a newer compiler may be optimising the code and if 
something needs to be volatile and is not drivers can break.

Also 4.10 has an extended shell. I strongly suggest you run the shell 
with the networking commands enabled. It will provide a valuable 
debugging aid.
