Make the mii_*() functions report advertised settings when autonegotiation if disabled. Suggested-by: Andrew Lunn Signed-off-by: Łukasz Stelmach Reviewed-by: Andrew Lunn --- This is the third version of ("net: phy: Prevent reporting advertised modes when autoneg is off") patch[1] that started as change for phy.c to make phy_ethtool_ksettings_get() work like mii_*() below. After suggestions from Russell King came v2[2]. Following Andrew Lunn's suggestions[2] to report advertised parameters even when autonegotiation is off I decided to drop changes to phy.c and make appropriate to mii.c Changes in v3: - drop changes to phy.c - introduce changes to mii.c Changes in v2: - clear lp_advertising - set ETHTOOL_LINK_MODE_TP_BIT and ETHTOOL_LINK_MODE_MII_BIT in advertising [1] https://lore.kernel.org/lkml/20201014125650.12137-1-l.stelmach@samsung.com/ [2] https://lore.kernel.org/lkml/20201015084435.24368-1-l.stelmach@samsung.com/ drivers/net/mii.c | 20 +++++++++++--------- 1 file changed, 11 insertions(+), 9 deletions(-) diff --git a/drivers/net/mii.c b/drivers/net/mii.c index f6a97c859f3a..e71ebb933266 100644 --- a/drivers/net/mii.c +++ b/drivers/net/mii.c @@ -84,15 +84,16 @@ int mii_ethtool_gset(struct mii_if_info *mii, struct ethtool_cmd *ecmd) ctrl1000 = mii->mdio_read(dev, mii->phy_id, MII_CTRL1000); stat1000 = mii->mdio_read(dev, mii->phy_id, MII_STAT1000); } + + ecmd->advertising |= mii_get_an(mii, MII_ADVERTISE); + if (mii->supports_gmii) + ecmd->advertising |= + mii_ctrl1000_to_ethtool_adv_t(ctrl1000); + if (bmcr & BMCR_ANENABLE) { ecmd->advertising |= ADVERTISED_Autoneg; ecmd->autoneg = AUTONEG_ENABLE; - ecmd->advertising |= mii_get_an(mii, MII_ADVERTISE); - if (mii->supports_gmii) - ecmd->advertising |= - mii_ctrl1000_to_ethtool_adv_t(ctrl1000); - if (bmsr & BMSR_ANEGCOMPLETE) { ecmd->lp_advertising = mii_get_an(mii, MII_LPA); ecmd->lp_advertising |= @@ -171,14 +172,15 @@ void mii_ethtool_get_link_ksettings(struct mii_if_info *mii, ctrl1000 = mii->mdio_read(dev, mii->phy_id, MII_CTRL1000); stat1000 = mii->mdio_read(dev, mii->phy_id, MII_STAT1000); } + + advertising |= mii_get_an(mii, MII_ADVERTISE); + if (mii->supports_gmii) + advertising |= mii_ctrl1000_to_ethtool_adv_t(ctrl1000); + if (bmcr & BMCR_ANENABLE) { advertising |= ADVERTISED_Autoneg; cmd->base.autoneg = AUTONEG_ENABLE; - advertising |= mii_get_an(mii, MII_ADVERTISE); - if (mii->supports_gmii) - advertising |= mii_ctrl1000_to_ethtool_adv_t(ctrl1000); - if (bmsr & BMSR_ANEGCOMPLETE) { lp_advertising = mii_get_an(mii, MII_LPA); lp_advertising |=
