Date: Tue, 26 May 2020 17:01:48 +0200 From: Antoine Tenart <antoine.tenart@...tlin.com> To: davem@...emloft.net, andrew@...n.ch, f.fainelli@...il.com, hkallweit1@...il.com Cc: Antoine Tenart <antoine.tenart@...tlin.com>, netdev@...r.kernel.org, linux-kernel@...r.kernel.org, alexandre.belloni@...tlin.com, thomas.petazzoni@...tlin.com, allan.nielsen@...rochip.com, vladimir.oltean@....com Subject: [PATCH net-next 1/2] net: mscc: use the PHY MII ioctl interface when possible Allow ioctl to be implemented by the PHY, when a PHY is attached to the Ocelot switch. In case the ioctl is a request to set or get the hardware timestamp, use the Ocelot switch implementation for now.
