net: dpaa: fman_memac: accept phy-interface-type = "10gbase-r" in the device tree Since commit 5d93cfcf7360 ("net: dpaa: Convert to phylink"), we support the "10gbase-r" phy-mode through a driver-based conversion of "xgmii", but we still don't actually support it when the device tree specifies "10gbase-r" proper. This is because boards such as LS1046A-RDB do not define pcs-handle-names (for whatever reason) in the ethernet@f0000 device tree node, and the code enters through this code path: err = of_property_match_string(mac_node, "pcs-handle-names", "xfi"); // code takes neither branch and falls through if (err >= 0) { (...) } else if (err != -EINVAL && err != -ENODATA) { goto _return_fm_mac_free; } (...) /* For compatibility, if pcs-handle-names is missing, we assume this * phy is the first one in pcsphy-handle */ err = of_property_match_string(mac_node, "pcs-handle-names", "sgmii"); if (err == -EINVAL || err == -ENODATA) pcs = memac_pcs_create(mac_node, 0); // code takes this branch else if (err < 0) goto _return_fm_mac_free; else pcs = memac_pcs_create(mac_node, err); // A default PCS is created and saved in "pcs" // This determination fails and mistakenly saves the default PCS // memac->sgmii_pcs instead of memac->xfi_pcs, because at this // stage, mac_dev->phy_if == PHY_INTERFACE_MODE_10GBASER. if (err && mac_dev->phy_if == PHY_INTERFACE_MODE_XGMII) memac->xfi_pcs = pcs; else memac->sgmii_pcs = pcs; In other words, in the absence of pcs-handle-names, the default xfi_pcs assignment logic only works when in the device tree we have PHY_INTERFACE_MODE_XGMII. By reversing the order between the fallback xfi_pcs assignment and the "xgmii" overwrite with "10gbase-r", we are able to support both values in the device tree, with identical behavior. Currently, it is impossible to make the s/xgmii/10gbase-r/ device tree conversion, because it would break forward compatibility (new device tree with old kernel). The only way to modify existing device trees to phy-interface-mode = "10gbase-r" is to fix stable kernels to accept this value and handle it properly. One reason why the conversion is desirable is because with pre-phylink kernels, the Aquantia PHY driver used to warn about the improper use of PHY_INTERFACE_MODE_XGMII [1]. It is best to have a single (latest) device tree that works with all supported stable kernel versions. Note that the blamed commit does not constitute a regression per se. Older stable kernels like 6.1 still do not work with "10gbase-r", but for a different reason. That is a battle for another time.

net: dpaa: Convert to phylink This converts DPAA to phylink. All macs are converted. This should work with no device tree modifications (including those made in this series), except for QSGMII (as noted previously). The mEMAC configuration is one of the tricker areas. I have tried to capture all the restrictions across the various models. Most of the time, we assume that if the serdes supports a mode or the phy-interface-mode specifies it, then we support it. The only place we can't do this is (RG)MII, since there's no serdes. In that case, we rely on a (new) devicetree property. There are also several cases where half-duplex is broken. Unfortunately, only a single compatible is used for the MAC, so we have to use the board compatible instead. The 10GEC conversion is very straightforward, since it only supports XAUI. There is generally nothing to configure. The dTSEC conversion is broadly similar to mEMAC, but is simpler because we don't support configuring the SerDes (though this can be easily added) and we don't have multiple PCSs. From what I can tell, there's nothing different in the driver or documentation between SGMII and 1000BASE-X except for the advertising. Similarly, I couldn't find anything about 2500BASE-X. In both cases, I treat them like SGMII. These modes aren't used by any in-tree boards. Similarly, despite being mentioned in the driver, I couldn't find any documented SoCs which supported QSGMII. I have left it unimplemented for now. Signed-off-by: Sean Anderson <sean.anderson@seco.com> Signed-off-by: David S. Miller <davem@davemloft.net>

net: fman: memac: Use lynx pcs driver Although not stated in the datasheet, as far as I can tell PCS for mEMACs is a "Lynx." By reusing the existing driver, we can remove the PCS management code from the memac driver. This requires calling some PCS functions manually which phylink would usually do for us, but we will let it do that soon. One problem is that we don't actually have a PCS for QSGMII. We pretend that each mEMAC's MDIO bus has four QSGMII PCSs, but this is not the case. Only the "base" mEMAC's MDIO bus has the four QSGMII PCSs. This is not an issue yet, because we never get the PCS state. However, it will be once the conversion to phylink is complete, since the links will appear to never come up. To get around this, we allow specifying multiple PCSs in pcsphy. This breaks backwards compatibility with old device trees, but only for QSGMII. IMO this is the only reasonable way to figure out what the actual QSGMII PCS is. Additionally, we now also support a separate XFI PCS. This can allow the SerDes driver to set different addresses for the SGMII and XFI PCSs so they can be accessed at the same time.

net: dpaa: Adjust queue depth on rate change Instead of setting the queue depth once during probe, adjust it on the fly whenever we configure the link. This is a bit unusal, since usually the DPAA driver calls into the FMAN driver, but here we do the opposite. We need to add a netdev to struct mac_device for this, but it will soon live in the phylink config. I haven't tested this extensively, but it doesn't seem to break anything. We could possibly optimize this a bit by keeping track of the last rate, but for now we just update every time. 10GEC probably doesn't need to call into this at all, but I've added it for consistency.

ethernet: constify references to netdev->dev_addr in drivers This big patch sprinkles const on local variables and function arguments which may refer to netdev->dev_addr. Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. Some of the changes here are not strictly required - const is sometimes cast off but pointer is not used for writing. It seems like it's still better to add the const in case the code changes later or relevant -W flags get enabled for the build. No functional changes.

phy: Add an mdio_device structure Not all devices attached to an MDIO bus are phys. So add an mdio_device structure to represent the generic parts of an mdio device, and place this structure into the phy_device. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

fsl/fman: Add FMan MAC support Add the Data Path Acceleration Architecture Frame Manger MAC support. This patch adds The FMan MAC configuration, initialization and runtime control routines. This patch contains support for these types of MACs: - dTSEC: Three speed Ethernet controller (10/100/1000 Mbps) - tGEC: 10G Ethernet controller (10 Gbps) - mEMAC: Multi-rate Ethernet MAC (10/100/1000/10000 Mbps) Different FMan revisions have different type and number of MACs.
