Date: Tue, 4 Feb 2014 03:33:09 +0400 From: Max Filippov <jcmvbkbc@...il.com> To: linux-xtensa@...ux-xtensa.org, netdev@...r.kernel.org Cc: Chris Zankel <chris@...kel.net>, Marc Gauthier <marc@...ence.com>, "David S. Miller" <davem@...emloft.net>, Ben Hutchings <ben@...adent.org.uk>, Florian Fainelli <f.fainelli@...il.com>, Max Filippov <jcmvbkbc@...il.com> Subject: [PATCH v3 1/2] net: ethoc: don't advertise gigabit speed on attached PHY OpenCores 10/100 Mbps MAC does not support speeds above 100 Mbps, but does not disable advertisement when PHY supports them. This results in non-functioning network when the MAC is connected to a gigabit PHY connected to a gigabit switch. The fix is to disable gigabit speed advertisement on attached PHY unconditionally. Signed-off-by: Max Filippov <jcmvbkbc@...il.com> --- Changes v2->v3: - don't call phy_start_aneg to force phylib to disable gigabit advertisement. Changes v1->v2: - disable both gigabit advertisement and support. drivers/net/ethernet/ethoc.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/drivers/net/ethernet/ethoc.c b/drivers/net/ethernet/ethoc.c index 5ca7719..6aef639 100644 --- a/drivers/net/ethernet/ethoc.c +++ b/drivers/net/ethernet/ethoc.c @@ -691,6 +691,11 @@ static int ethoc_mdio_probe(struct net_device *dev) } priv->phy = phy; + phy->advertising &= ~(ADVERTISED_1000baseT_Full | + ADVERTISED_1000baseT_Half); + phy->supported &= ~(SUPPORTED_1000baseT_Full | + SUPPORTED_1000baseT_Half); + return 0; } -- 1.8.1.4 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
