[PATCH net-next v17 02/14] net: sfp: pass the phy_device when disconnecting an sfp module's PHY

From: Maxime Chevallier
Date: Tue Jul 09 2024 - 02:31:50 EST


Pass the phy_device as a parameter to the sfp upstream .disconnect_phy
operation. This is preparatory work to help track phy devices across
a net_device's link.
