I think using CDL is a nicer solution. I've made the interrupt
priority a CDL option with a default value of 3 so we retain the
original behavior. You can then override it as needed. 

In the hardware specific part of the ethernet driver put something like

   requires CYGNUM_DEVS_ETH_SMSC_LAN91CXX_INT_PRIO==4

The CDL engine will then override the default value with 4.

Please could you test this patch and let me know how it goes.
