Subject[PATCH] net: ethernet: ti: cpsw: make array stpa static const, makes object smaller
Date
From: Colin Ian King <colin.king@canonical.com>

Don't populate the array stpa on the stack but instead it
static const. Makes the object code smaller by 81 bytes:

Before:
text data bss dec hex filename
54993 17248 0 72241 11a31 ./drivers/net/ethernet/ti/cpsw_new.o

After:
text data bss dec hex filename
54784 17376 0 72160 119e0 ./drivers/net/ethernet/ti/cpsw_new.o

(gcc version 10.3.0)
