From 3fb677c69a15b786354c0d6f69825f3270ec9cc2 Mon Sep 17 00:00:00 2001 From: Russell King Date: Fri, 13 Jan 2017 11:17:30 +0000 Subject: net: phy: hook up clause 45 autonegotiation restart genphy_restart_aneg() can only restart autonegotiation on clause 22 PHYs. Add a phy_restart_aneg() function which selects between the clause 22 and clause 45 restart functionality depending on the PHY type.
