This breaks the ability to grep for the warning. Quoting Documentation/CodingStyle, Chapter 2: "However, never break user-visible strings such as printk messages, because that breaks the ability to grep for them."

Current e1000e driver doesn't tell nothing when Link Speed is downgraded due to SmartSpeed. As a result, users suspect that there is something wrong with NIC. If the cause of it is SmartSpeed, there is no means to replace NIC. This patch make e1000e notify users that SmartSpeed worked.
