-Subject: [PATCH 720/744] sfp: add phylink based SFP module support
-
-Add support for SFP hotpluggable modules via phylink.  This supports
-both copper and optical SFP modules, which require different Serdes
-modes in order to properly negotiate the link.
-
-Optical SFP modules typically require the Serdes link to be talking
-1000base-X mode - this is the gigabit ethernet mode defined by the
-802.3 standard.
-
-Copper SFP modules typically integrate a PHY in the module to convert
-from Serdes to copper, and the PHY will be configured by the vendor
-to either present a 1000base-X Serdes link (for fixed 1000base-T) or
-a SGMII Serdes link.  However, this is vendor defined, so we instead
-detect the PHY, switch the link to SGMII mode, and use traditional
-PHY based negotiation.
