[PATCH] hv_netvsc: make const array ver_list static, reduces object code size

From: Colin King
Date: Fri Sep 22 2017 - 11:50:30 EST


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

Don't populate const array ver_list on the stack, instead make it
static. Makes the object code smaller by over 400 bytes:

Before:
text data bss dec hex filename
18444 3168 320 21932 55ac drivers/net/hyperv/netvsc.o

After:
text data bss dec hex filename
17950 3224 320 21494 53f6 drivers/net/hyperv/netvsc.o

(gcc 6.3.0, x86-64)
