From 898805e0cdf7fd860ec21bf661d3a0285a3defbd Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 30 May 2017 16:21:51 +0100 Subject: [PATCH] net: phy: fix marvell phy status reading The Marvell driver incorrectly provides phydev->lp_advertising as the logical and of the link partner's advert and our advert. This is incorrect - this field is supposed to store the link parter's unmodified advertisment. This allows ethtool to report the correct link partner auto-negotiation status.
