Subject: [PATCH 647/660] net: sfp: move phy_start()/phy_stop() to phylink
|
|
|
|
Move phy_start() and phy_stop() into the module_start and module_stop
|
|
notifications in phylink, rather than having them in the SFP code.
|
|
This gives phylink responsibility for controlling the PHY, rather
|
|
than having SFP start and stop the PHY state machine.
