From 4ed311b08a91fe0a214714605d8159fc51166982 Mon Sep 17 00:00:00 2001 From: Gerhard Engleder Date: Thu, 19 Aug 2021 15:11:52 +0200 Subject: net: phy: Support set_loopback override phy_read_status and various other PHY functions support PHY specific overriding of driver functions by using a PHY specific pointer to the PHY driver. Add support of PHY specific override to phy_loopback too. Signed-off-by: Gerhard Engleder Signed-off-by: David S.
