From 7ff4f3f315db361e35c1d61a6fdbfddbe345b633 Mon Sep 17 00:00:00 2001 From: Antoine Tenart Date: Tue, 26 May 2020 17:01:48 +0200 Subject: [PATCH] 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. Signed-off-by: Antoine Tenart Reviewed-by: Andrew Lunn Signed-off-by: David S.
