[PATCH net-next 0/3] Adding PHY Loopback tunable
Hi All, This series add support for PHY Loopback tunable, and implement it for MSCC phys. To configure loopback, the ethtool_tunable structure is used. 'id' must be set to 'ETHTOOL_PHY_LOOPBACK' and 'data' specifies the loopback type: ETHTOOL_PHY_LOOPBACK_* (DISABLE, NEAR, FAR or EXTN). Here is how to configure loopback using ethtool: Ethtool Help: ethtool -h for PHY tunables ethtool --set-phy-tunable DEVNAME Set PHY tunable [ loopback off|near|far|extn ] ethtool --get-phy-tunable DEVNAME Get PHY tunable [ loopback ] Ethtool ex: ethtool --set-phy-tunable eth0 loopback near ethtool --set-phy-tunable eth0 loopback far ethtool --set-phy-tunable eth0 loopback extn ethtool --set-phy-tunable eth0 loopback off ethtool --get-phy-tunable eth0 loopback Patches to ethtool will follow shortly. The feature is tested on Beaglebone Black with VSC 8531 PHY. Please review. Best regards Allan and Raju Raju Lakkaraju (3): ethtool: (uapi) Add ETHTOOL_PHY_LOOPBACK to PHY tunables ethtool: Core impl for ETHTOOL_PHY_LOOPBACK tunable. net: phy: Add Loopback support in Microsemi PHYs driver drivers/net/phy/mscc.c | 118 +++ include/uapi/linux/ethtool.h | 8 +++ net/core/ethtool.c | 2 + 3 files changed, 128 insertions(+) -- 2.7.3
