Miller" <davem@...emloft.net>, Willy Tarreau <w@....eu> Subject: [PATCH 3.10 102/139] net: phy: fix marvell phy status reading From: Russell King <rmk+kernel@...linux.org.uk> commit 898805e0cdf7fd860ec21bf661d3a0285a3defbd upstream. 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.
