From 4882057ad434e8a6434fce20dc7b7315d40a9d4a Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 11 Dec 2019 10:56:14 +0000 Subject: 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. Reviewed-by: Andrew Lunn Signed-off-by: Russell King Signed-off-by: David S.
