2019-12-25net: Add a layer for non-PHY MII time stamping drivers.Richard Cochran2-0/+127
While PHY time stamping drivers can simply attach their interface directly to the PHY instance, stand alone drivers require support in order to manage their services. Non-PHY MII time stamping drivers have a control interface over another bus like I2C, SPI, UART, or via a memory mapped peripheral. The controller device will be associated with one or more time stamping channels, each of which sits snoops in on a MII bus. This patch provides a glue layer that will enable time stamping channels to find their controlling device.

2019-12-25net: Introduce a new MII time stamping interface.Richard Cochran3-17/+28
Currently the stack supports time stamping in PHY devices. However, there are newer, non-PHY devices that can snoop an MII bus and provide time stamps. In order to support such devices, this patch introduces a new interface to be used by both PHY and non-PHY devices. In addition, the one and only user of the old PHY time stamping API is converted to the new interface.

2019-12-25net: phy: dp83640: Move the probe and remove methods around.Richard Cochran1-90/+90
An upcoming patch will change how the PHY time stamping functions are registered with the networking stack, and adapting this driver would entail adding forward declarations for four time stamping methods. However, forward declarations are considered to be stylistic defects. This patch avoids the issue by moving the probe and remove methods immediately above the phy_driver interface structure.

2019-12-17net: phylink: extend clause 45 PHY validation workaroundRussell King1-9/+13
Commit e45d1f5288b8 ("net: phylink: support Clause 45 PHYs on SFP+ modules") added a workaround to support clause 45 PHYs which dynamically switch their interface mode on SFP+ modules. This was implemented by validating the PHYs supported/advertising using PHY_INTERFACE_MODE_NA, rather than the specific interface mode that we attached the PHY with. However, we already have a situation where phylink is used to connect a Marvell 88X3310 PHY which also behaves in exactly the same way, but which seemingly doesn't need this. The reason seems to be that the mvpp2 driver sets a whole bunch of link modes for PHY_INTERFACE_MODE_10GKR down to 10Mb/s, despite 10GBASE-R not actually supporting anything but 10Gb/s speeds. When testing with drivers that (correctly) take the mvneta approach, where the validate() method only returns what can be supported / advertised for the specified link mode, we find that Clause 45 PHYs do not behave as we expect: their advertisement is restricted to what the current link will support, rather than what the PHY supports through its dynamic switching. Extend this workaround to all such cases; if we have a Clause 45 PHY attaching via any means, except in USXGMII, XAUI and RXAUI which are all unable to support this dynamic switching or have other solutions to it, then we need to validate using PHY_INTERFACE_MODE_NA. This should allow mvpp2 to switch to a more conformant validate() implementation. Signed-off-by: Russell King <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2019-12-17net: phylink: improve clause 45 PHY ksettings_set implementationRussell King1-31/+53
While testing ethtool with the Methode DM7052 module, it was noticed that attempting to set the advertising mask results in the mask being truncated to the support offered by the currently chosen PHY interface mode. When a PHY dynamically changes the PHY interface mode, limiting the advertising mask in this way is not correct - if the PHY happened to negotiate 10GBASE-T, and selected 10GBASE-R as the host interface, we don't want to restrict the advertisement to just 10GBASE-* modes. Rework setting the advertisement to take account of this; do not pass the requested advertisement through phylink_validate(), but rely on the advertisement restriction (supported mask) set when the PHY was initially setup.

Knowing whether we need to delay the MAC configuration because a module may have a PHY is useful to phylink to allow NBASE-T modules to work on systems supporting no more than 2.5G speeds. This commit allows us to delay such configuration until after the PHY has been probed by recording the parsed capabilities, and if the module may have a PHY, doing no more until the module_start() notification is called. At that point, we either have a PHY, or we don't.

2019-12-11net: sfp: add module start/stop upstream notificationsRussell King3-0/+31
When dealing with some copper modules, we can't positively know the module capabilities are until we have probed the PHY. Without the full capabilities, we may end up failing a module that we could otherwise drive with a restricted set of capabilities. An example of this would be a module with a NBASE-T PHY plugged into a host that supports phy interface modes 2500BASE-X and SGMII. The PHY supports 10GBASE-R, 5000BASE-X, 2500BASE-X, SGMII interface modes, which means a subset of the capabilities are compatible with the host. However, reading the module EEPROM leads us to believe that the module only supports ethtool link mode 10GBASE-T, which is incompatible with the host - and thus results in the module being rejected. This patch adds an extra notification which are triggered after the SFP module's PHY probe, and a corresponding notification just before the PHY is removed.
