net: phylink: add phylink_expects_phy() method

2023-04-13T15:02:37Z

[ Upstream commit 653a180957a85c3fc30320cc7e84f5dc913a64f8 ] Provide phylink_expects_phy() to allow MAC drivers to check if it is expecting a PHY to attach to. Since fixed-linked setups do not need to attach to a PHY. Provides a boolean value as to if the MAC should expect a PHY. Returns true if a PHY is expected.

net: remove explicit phylink_generic_validate() references

2022-11-08T01:54:57Z

Virtually all conventional network drivers are now converted to use phylink_generic_validate() - only DSA drivers and fman_memac remain, so lets remove the necessity for network drivers to explicitly set this member, and default to phylink_generic_validate() when unset. This is possible as .validate must currently be set. Any remaining instances that have not been addressed by this patch can be fixed up later.

net: phylink: add phylink_get_link_timer_ns() helper

2022-10-29T04:48:30Z

Add a helper to convert the PHY interface mode to the required link timer setting as stated by the appropriate standard. Inappropriate interface modes return an error. Signed-off-by: Russell King (Oracle) Signed-off-by: Jakub Kicinski

net: phylink: add mac_managed_pm in phylink_config structure

2022-10-15T10:51:51Z

The recent commit 'commit 744d23c71af3 ("net: phy: Warn about incorrect mdio_bus_phy_resume() state")' requires the MAC driver explicitly tell the phy driver who is managing the PM, otherwise you will see warning during resume stage. Add a boolean property in the phylink_config structure so that the MAC driver can use it to tell the PHY driver if it wants to manage the PM.

net: phylink: Adjust advertisement based on rate matching

2022-09-23T10:55:36Z

This adds support for adjusting the advertisement for pause-based rate matching. This may result in a lossy link, since the final link settings are not adjusted. Asymmetric pause support is necessary. It would be possible for a MAC supporting only symmetric pause to use pause-based rate adaptation, but only if pause reception was enabled as well.

net: phylink: Adjust link settings based on rate matching

2022-09-23T10:55:35Z

If the phy is configured to use pause-based rate matching, ensure that the link is full duplex with pause frame reception enabled. As suggested, if pause-based rate matching is enabled by the phy, then pause reception is unconditionally enabled. The interface duplex is determined based on the rate matching type. When rate matching is enabled, so is the speed. We assume the maximum interface speed is used. This is only relevant for MLO_AN_PHY. For MLO_AN_INBAND, the MAC/PCS's view of the interface speed will be used. Although there are no RATE_ADAPT_CRS phys in-tree, it has been added for comparison (and the implementation is quite simple).

net: phylink: Generate caps and convert to linkmodes separately

2022-09-23T10:55:35Z

If we call phylink_caps_to_linkmodes directly from phylink_get_linkmodes, it is difficult to re-use this functionality in MAC drivers. This is because MAC drivers must then work with an ethtool linkmode bitmap, instead of with mac capabilities. Instead, let the caller of phylink_get_linkmodes do the conversion. To reflect this change, rename the function to phylink_get_capabilities. Signed-off-by: Sean Anderson Signed-off-by: David S. Miller

This function is convenient for MAC drivers. They can use it to add or remove particular link modes based on capabilities (such as if half duplex is not supported for a particular interface mode). Signed-off-by: Sean Anderson Signed-off-by: David S. Miller
