net: phy: fix MDIO bus PM PHY resuming

2020-03-12T22:36:12Z

So far we have the unfortunate situation that mdio_bus_phy_may_suspend() is called in suspend AND resume path, assuming that function result is the same. After the original change this is no longer the case, resulting in broken resume as reported by Geert. To fix this call mdio_bus_phy_may_suspend() in the suspend path only, and let the phy_device store the info whether it was suspended by MDIO bus PM.

net: phy: avoid clearing PHY interrupts twice in irq handler

2020-03-02T03:04:19Z

On all PHY drivers that implement did_interrupt() reading the interrupt status bits clears them. This means we may loose an interrupt that is triggered between calling did_interrupt() and phy_clear_interrupt(). As part of the fix make it a requirement that did_interrupt() clears the interrupt. The Fixes tag refers to the first commit where the patch applies cleanly.

net: phy: add new version of phy_do_ioctl

2020-01-21T09:50:41Z

Add a new version of phy_do_ioctl that doesn't check whether net_device is running. It will typically be used if suitable drivers attach the PHY in probe already. Signed-off-by: Heiner Kallweit Reviewed-by: Florian Fainelli Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: rename phy_do_ioctl to phy_do_ioctl_running

2020-01-21T09:50:41Z

We just added phy_do_ioctl, but it turned out that we need another version of this function that doesn't check whether net_device is running. So rename phy_do_ioctl to phy_do_ioctl_running.

net: phy: add generic ndo_do_ioctl handler phy_do_ioctl

2020-01-20T09:43:24Z

A number of network drivers has the same glue code to use phy_mii_ioctl as ndo_do_ioctl handler. So let's add such a generic ndo_do_ioctl handler to phylib. Signed-off-by: Heiner Kallweit Signed-off-by: David S. Miller

net: phy: Maintain MDIO device and bus statistics

2020-01-17T10:12:44Z

We maintain global statistics for an entire MDIO bus, as well as broken down, per MDIO bus address statistics. Given that it is possible for MDIO devices such as switches to access MDIO bus addresses for which there is not a mdio_device instance created (therefore not a a corresponding device directory in sysfs either), we also maintain per-address statistics under the statistics folder. The layout looks like this: /sys/class/mdio_bus/../statistics/ transfers errrors writes reads transfers_ errors_ writes_ reads_ When a mdio_device instance is registered, a statistics/ folder is created with the tranfers, errors, writes and reads attributes which point to the appropriate MDIO bus statistics structure. Statistics are 64-bit unsigned quantities and maintained through the u64_stats_sync.h helper functions.

net: phy: add MACsec ops in phy_device

2020-01-14T19:31:41Z

This patch adds a reference to MACsec ops in the phy_device, to allow PHYs to support offloading MACsec operations. The phydev lock will be held while calling those helpers. Signed-off-by: Antoine Tenart Signed-off-by: David S. Miller

net: macsec: introduce the macsec_context structure

2020-01-14T19:31:41Z

This patch introduces the macsec_context structure. It will be used in the kernel to exchange information between the common MACsec implementation (macsec.c) and the MACsec hardware offloading implementations. This structure contains pointers to MACsec specific structures which contain the actual MACsec configuration, and to the underlying device (phydev for now).

net: phy: Added IRQ print to phylink_bringup_phy()

2020-01-14T18:56:58Z

The information about the PHY attached to the PHYLINK instance is useful but is missing the IRQ prints that phy_attached_info() adds. phy_attached_info() is a bit long and it would not be possible to use phylink_info() anyway. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller
