Subject: [PATCH 31/62] netxen: 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
  18658	  16443	   4312	  39413	   99f5	drivers/net/netxen/netxen_nic_hw.o.new
  18714	  16443	   4312	  39469	   9a2d	drivers/net/netxen/netxen_nic_hw.o.old

Changed nx_p3_nic_add_mac to take a const u8 *
Used ARRAY_SIZE instead of magic number.
