4.9-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit a8bf879af7b1999eba36303ce9cc60e0e7dd816c ]
Add the two 1000BaseLX enum values to the X550's check for 1Gbps modules, allowing the core driver code to establish a link over this SFP type.
This is done by the out-of-tree driver but the fix wasn't in mainline.
