Subject: [PATCH] net: phy: fix marvell phy status reading
Date: Tue, 30 May 2017 16:21:51 +0100	[thread overview]
Message-ID: <E1dFixz-00062r-0n@rmk-PC.armlinux.org.uk> (raw)

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.
