Subject: [net-next 7/9] bnx2x: changed iscsi/fcoe mac init and macros
From: Dmitry Kravkov <dmitry@...adcom.com>
This includes changes in macros to better distinguish between the two
protocols, and slightly changed the way their macs are set.
Notice this file contains string print lines with more than 80 characters,
as to not break prints.
