[PATCH] net: stmmac: make const array route_possibilities static

From: Colin King
Date: Tue Jul 11 2017 - 07:18:55 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

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
