From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Don't populate const array patterns on the stack, instead make it
static. Makes the object code smaller by over 60 bytes:
Before:
text data bss dec hex filename
1953 496 0 2449 991 i40e_diag.o
After:
text data bss dec hex filename
1798 584 0 2382 94e i40e_diag.o
(gcc 6.3.0, x86-64)
