From 9b1120455f33d5bf98831444820e679a912479c4 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.
