Subject: net/mlx4_en: ethtool: make array modes static const, makes object
 smaller
Patch-mainline: v5.4-rc1
Git-commit: c21815f1c199a2ffb77aa862206b0f8d94263d14
References: jsc#SLE-8460

Don't populate the array modes on the stack but instead make it
static const. Makes the object code smaller by 303 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
  51240	   5008	   1312	  57560	   e0d8 mellanox/mlx4/en_ethtool.o

After:
   text	   data	    bss	    dec	    hex	filename
  50937	   5008	   1312	  57257	   dfa9	mellanox/mlx4/en_ethtool.o

(gcc version 9.2.1, amd64)
