Subject[PATCH] net: hns3: make array spec_opcode static const, makes object smaller
Date
From: Colin Ian King <colin.king@canonical.com>

Don't populate the array spec_opcode on the stack but instead make it
static const. Makes the object code smaller by 48 bytes.

Before:
text data bss dec hex filename
6914 1040 128 8082 1f92 hns3/hns3vf/hclgevf_cmd.o

After:
text data bss dec hex filename
6866 1040 128 8034 1f62 hns3/hns3vf/hclgevf_cmd.o

(gcc version 9.2.1, amd64)
