net: phylink: add phylink_expects_phy() method

2023-03-31T08:23:41+00:00

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. Reviewed-by: Russell King (Oracle) Signed-off-by: Michael Sit Wei Hong Signed-off-by: David S.

net: phylink: support validated pause and autoneg in fixed-link

2023-02-15T10:35:27+00:00

In fixed-link setup phylink_parse_fixedlink() unconditionally sets Pause, Asym_Pause and Autoneg bits to "supported" bitmap, while MAC may not support these. This leads to ethtool reporting: > Supported pause frame use: Symmetric Receive-only > Supports auto-negotiation: Yes regardless of what is actually supported. Instead of unconditionally set Pause, Asym_Pause and Autoneg it is sensible to set them according to validated "supported" bitmap, i.e. the result of phylink_validate().

net: phylink: move phy_device_free() to correctly release phy device

2023-02-03T09:13:53+00:00

After calling fwnode_phy_find_device(), the phy device refcount is incremented. Then, when the phy device is attached to a netdev with phy_attach_direct(), the refcount is also incremented but only decremented in the caller if phy_attach_direct() fails. Move phy_device_free() before the "if" to always release it correctly. Indeed, either phy_attach_direct() failed and we don't want to keep a reference to the phydev or it succeeded and a reference has been taken internally.

drivers/net/phy: add the link modes for the 10BASE-T1S Ethernet PHY

2023-01-11T08:35:02+00:00

This patch adds the link modes for the IEEE 802.3cg Clause 147 10BASE-T1S Ethernet PHY. According to the specifications, the 10BASE-T1S supports Point-To-Point Full-Duplex, Point-To-Point Half-Duplex and/or Point-To-Multipoint (AKA Multi-Drop) Half-Duplex operations.

net: phylink: fix PHY validation with rate adaption

2022-11-28T11:12:39+00:00

Tim Harvey reports that link modes which he does not expect to be supported are being advertised, and this is because of the workaround we have for PHYs that switch interface modes. Fix this up by checking whether rate matching will be used for the requested interface mode, and if rate matching will be used, perform validation only with the requested interface mode, rather than invoking this workaround.

net: remove explicit phylink_generic_validate() references

2022-11-08T01:54:57+00:00

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.

phylink: require valid state argument to phylink_validate_mask_caps()

2022-10-27T02:07:43+00:00

state is deferenced earlier in the function, the NULL check is pointless. Since we don't have any crash reports presumably it's safe to assume state is not NULL.
