From de1d66333983e0c80b551518ab62f11102969e6a Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 26 Aug 2019 12:19:35 +0100 Subject: net: phy: provide phy driver start/stop hooks Provide phy driver start/stop hooks so that the PHY driver knows when the network driver is starting or stopping. This will be used for the Marvell 10G driver so that we can sanely refuse to start if the PHYs firmware is not present, and also so that we can sanely support SFPs behind the PHY.
