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.
