-Subject: [PATCH 719/744] phylink: add hooks for SFP support
-
-Add support to phylink for SFP, which needs to control and configure
-the ethernet MAC link state. Specifically, SFP needs to:
-
-1. set the negotiation mode between SGMII and 1000base-X
-2. attach and detach the module PHY
-3. prevent the link coming up when errors are reported
-
-In the absence of a PHY, we also need to set the ethtool port type
-according to the module plugged in.
-
