Don't populate array route_possibilities on the stack but make it
static const.  Makes the object code a little smaller by 85 bytes:

Before:
   text    data     bss     dec     hex filename
   9901    2448       0   12349    303d dwmac4_core.o

After:
   text    data     bss     dec     hex filename
   9760    2504       0   12264    2fe8 dwmac4_core.o
