Subject: [PATCH 28/62] ixgb: Use static const

Using static const generally increases object text and decreases data size.
It also generally decreases overall object size.

   text	   data	    bss	    dec	    hex	filename
   4115	    416	    448	   4979	   1373	drivers/net/ixgb/ixgb_param.o.old
   3998	    416	    448	   4862	   12fe	drivers/net/ixgb/ixgb_param.o.new

Change struct ixgb_opt_list to const struct and
change char *str to const char *str.
