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.
