ethtool: implement Energy Detect Powerdown support via phy-tunable

2019-09-16T20:02:45Z

The `phy_tunable_id` has been named `ETHTOOL_PHY_EDPD` since it looks like this feature is common across other PHYs (like EEE), and defining `ETHTOOL_PHY_ENERGY_DETECT_POWER_DOWN` seems too long. The way EDPD works, is that the RX block is put to a lower power mode, except for link-pulse detection circuits. The TX block is also put to low power mode, but the PHY wakes-up periodically to send link pulses, to avoid lock-ups in case the other side is also in EDPD mode. Currently, there are 2 PHY drivers that look like they could use this new PHY tunable feature: the `adin` && `micrel` PHYs. The ADIN's datasheet mentions that TX pulses are at intervals of 1 second default each, and they can be disabled. For the Micrel KSZ9031 PHY, the datasheet does not mention whether they can be disabled, but mentions that they can modified. The way this change is structured, is similar to the PHY tunable downshift control: * a `ETHTOOL_PHY_EDPD_DFLT_TX_MSECS` value is exposed to cover a default TX interval; some PHYs could specify a certain value that makes sense * `ETHTOOL_PHY_EDPD_NO_TX` would disable TX when EDPD is enabled * `ETHTOOL_PHY_EDPD_DISABLE` will disable EDPD As noted by the `ETHTOOL_PHY_EDPD_DFLT_TX_MSECS` the interval unit is 1 millisecond, which should cover a reasonable range of intervals: - from 1 millisecond, which does not sound like much of a power-saver - to ~65 seconds which is quite a lot to wait for a link to come up when plugging a cable Reviewed-by: Andrew Lunn Reviewed-by: Florian Fainelli Signed-off-by: Alexandru Ardelean Signed-off-by: David S.

ethtool: Add SFF-8436 and SFF-8636 max EEPROM length definitions

2019-05-01T21:39:16Z

Added max EEPROM length defines for ethtool usage: #define ETH_MODULE_SFF_8636_MAX_LEN 640 #define ETH_MODULE_SFF_8436_MAX_LEN 640 These definitions are used to determine the EEPROM data length when reading high eeprom pages. For example, SFF-8636 EEPROM data from page 03h needs to be stored at data[512] - data[639]. Signed-off-by: Erez Alfasi Signed-off-by: Saeed Mahameed

ethtool: avoid signed-unsigned comparison in ethtool_validate_speed()

2019-04-08T23:30:43Z

When building C++ userspace code that includes ethtool.h with "-Werror -Wall", g++ complains about signed-unsigned comparison in ethtool_validate_speed() due to definition of SPEED_UNKNOWN as -1. Explicitly cast SPEED_UNKNOWN to __u32 to match type of ethtool_validate_speed() argument. Signed-off-by: Michael Zhivich Signed-off-by: David S. Miller

ethtool: add PHY Fast Link Down support

2019-03-27T20:51:49Z

This adds support for Fast Link Down as new PHY tunable. Fast Link Down reduces the time until a link down event is reported for 1000BaseT. According to the standard it's 750ms what is too long for several use cases. v2: - add comment describing the constants Signed-off-by: Heiner Kallweit Reviewed-by: Florian Fainelli Reviewed-by: Michal Kubecek Signed-off-by: David S.
