net: phy: mscc: fix firmware paths

2020-02-27T04:53:09+00:00

The firmware paths for the VSC8584 PHYs not not contain the leading 'microchip/' directory, as used in linux-firmware, resulting in an error when probing the driver. This patch fixes it.

net: phy: mscc: PN rollover support

2020-01-14T19:31:41+00:00

This patch adds support for handling MACsec PN rollover in the mscc PHY driver. When a flow rolls over, an interrupt is fired. This patch adds the logic to check all flows and identify the one rolling over in the handle_interrupt PHY helper, then disables the flow and report the event to the MACsec core.

net: phy: mscc: macsec support

2020-01-14T19:31:41+00:00

This patch adds MACsec offloading support to some Microsemi PHYs, to configure flows and transformations so that matched packets can be processed by the MACsec engine, either at egress, or at ingress. Signed-off-by: Antoine Tenart Signed-off-by: David S. Miller

net: phy: mscc: macsec initialization

2020-01-14T19:31:41+00:00

This patch adds support for initializing the MACsec engine found within some Microsemi PHYs. The engine is initialized in a passthrough mode and does not modify any incoming or outgoing packet. But thanks to this it now can be configured to perform MACsec transformations on packets, which will be supported by a future patch. The MACsec read and write functions are wrapped into two versions: one called during the init phase, and the other one later on. This is because the init functions in the Microsemi PHY driver are called while the MDIO bus lock is taken. Signed-off-by: Antoine Tenart Signed-off-by: David S. Miller

net: phy: remove redundant .aneg_done initialisers

2019-12-19T20:52:34+00:00

Remove initialisers that set .aneg_done to genphy_aneg_done - this is the default for clause 22 PHYs, so the initialiser is redundant. Signed-off-by: Russell King Reviewed-by: Andrew Lunn Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

net: phy: remove calls to genphy_config_init

2019-08-17T19:34:50+00:00

Supported PHY features are either auto-detected or explicitly set. In both cases calling genphy_config_init isn't needed. All that genphy_config_init does is removing features that are set as supported but can't be auto-detected. Basically it duplicates the code in genphy_read_abilities. Therefore remove such calls from all PHY drivers. v2: - remove call also from new adin PHY driver v3: - pass NULL as config_init function pointer for dp83848 Signed-off-by: Heiner Kallweit Signed-off-by: David S.
