net: phy: correct format of block comments

2021-06-16T19:34:07+00:00

Block comments should not use a trailing */ on a separate line and every line of a block comment should start with an '*'. Signed-off-by: Wenpeng Liang Signed-off-by: Weihang Li Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: Document core PHY structures

2020-09-24T01:02:49+00:00

Add kerneldoc for the core PHY data structures, a few inline functions and exported functions which are not already documented. v2 Typos g/phy/PHY/s Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller

ethtool: Add support for 100Gbps per lane link modes

2020-07-08T22:30:42+00:00

Define 100G, 200G and 400G link modes using 100Gbps per lane LR, ER and FR are defined as a single link mode because they are using same technology and by design are fully interoperable. EEPROM content indicates if the module is LR, ER, or FR, and the user space ethtool decoder is planned to support decoding these modes in the EEPROM.

net: mdiobus: add clause 45 mdiobus accessors

2020-05-26T22:31:45+00:00

There is a recurring pattern throughout some of the PHY code converting a devad and regnum to our packed clause 45 representation. Rather than having this scattered around the code, let's put a common translation function in mdio.h, and provide some register accessors. Convert the phylib core, phylink, bcm87xx and cortina to use these. Signed-off-by: Russell King Reviewed-by: Andrew Lunn Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

net: phy: add and use phy_check_downshift

2020-03-24T04:09:47+00:00

So far PHY drivers have to check whether a downshift occurred to be able to notify the user. To make life of drivers authors a little bit easier move the downshift notification to phylib. phy_check_downshift() compares the highest mutually advertised speed with the actual value of phydev->speed (typically read by the PHY driver from a vendor-specific register) to detect a downshift. v2: - Add downshift hint to phy_print_status Signed-off-by: Heiner Kallweit Signed-off-by: David S. Miller

net: mdiobus: add APIs for modifying a MDIO device register

2020-03-18T05:51:16+00:00

Add APIs for modifying a MDIO device register, similar to the existing phy_modify() group of functions, but at mdiobus level instead. Adapt __phy_modify_changed() to use the new mdiobus level helper. Signed-off-by: Russell King Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

ethtool: Add support for low latency RS FEC

2020-02-19T03:17:31+00:00

Add support for low latency Reed Solomon FEC as LLRS. The LL-FEC is defined by the 25G/50G ethernet consortium, in the document titled "Low Latency Reed Solomon Forward Error Correction" Signed-off-by: Aya Levin Reviewed-by: Eran Ben Elisha CC: Andrew Lunn Signed-off-by: Saeed Mahameed Reviewed-by: Andrew Lunn

net: phy: don't crash in phy_read/_write_mmd without a PHY driver

2020-01-20T09:08:20+00:00

The APIs can be used by Ethernet drivers without actually loading a PHY driver. This may become more widespread in the future with 802.3z compatible MAC PCS devices being locally driven by the MAC driver when configuring for a PHY mode with in-band negotiation. Check that drv is not NULL before reading from it. Signed-off-by: Alex Marginean Signed-off-by: Vladimir Oltean Signed-off-by: David S. Miller
