net: remove phy_has_hwtstamp() -> phy_mii_ioctl() decision from converted drivers It is desirable that the new .ndo_hwtstamp_set() API gives more uniformity, less overhead and future flexibility w.r.t. the PHY timestamping behavior. Currently there are some drivers which allow PHY timestamping through the procedure mentioned in Documentation/networking/timestamping.rst. They don't do anything locally if phy_has_hwtstamp() is set, except for lan966x which installs PTP packet traps. Centralize that behavior in a new dev_set_hwtstamp_phylib() code function, which calls either phy_mii_ioctl() for the phylib PHY, or .ndo_hwtstamp_set() of the netdev, based on a single policy (currently simplistic: phy_has_hwtstamp()). Any driver converted to .ndo_hwtstamp_set() will automatically opt into the centralized phylib timestamping policy. Unconverted drivers still get to choose whether they let the PHY handle timestamping or not. Netdev drivers with integrated PHY drivers that don't use phylib presumably don't set dev->phydev, and those will always see HWTSTAMP_SOURCE_NETDEV requests even when converted. The timestamping policy will remain 100% up to them.

net: sparx5: convert to ndo_hwtstamp_get() and ndo_hwtstamp_set() The hardware timestamping through ndo_eth_ioctl() is going away. Convert the sparx5 driver to the new API before that can be removed. After removing the timestamping logic from sparx5_port_ioctl(), the rest is equivalent to phy_do_ioctl().

net: sparx5: fix bitmask on 32-bit targets I saw the build failure that was fixed in commit 6387f65e2acb ("net: sparx5: fix compiletime_assert for GCC 4.9") and noticed another issue that was introduced in the same patch: Using GENMASK() to create a 64-bit mask does not work on 32-bit architectures. This probably won't ever happen on this driver since it's specific to a 64-bit SoC, but it's better to write it portably, so use GENMASK_ULL() instead.

net: sparx5: add port module support This add configuration of the Sparx5 port module instances. Sparx5 has in total 65 logical ports (denoted D0 to D64) and 33 physical SerDes connections (S0 to S32). The 65th port (D64) is fixed allocated to SerDes0 (S0). The remaining 64 ports can in various multiplexing scenarios be connected to the remaining 32 SerDes using QSGMII, or USGMII or USXGMII extenders. 32 of the ports can have a 1:1 mapping to the 32 SerDes. Some additional ports (D65 to D69) are internal to the device and do not connect to port modules or SerDes macros. For example, internal ports are used for frame injection and extraction to the CPU queues. The 65 logical ports are split up into the following blocks. - 13 x 5G ports (D0-D11, D64) - 32 x 2G5 ports (D16-D47) - 12 x 10G ports (D12-D15, D48-D55) - 8 x 25G ports (D56-D63) Each logical port supports different line speeds, and depending on the speeds supported, different port modules (MAC+PCS) are needed. A port supporting 5 Gbps, 10 Gbps, or 25 Gbps as maximum line speed, will have a DEV5G, DEV10G, or DEV25G module to support the 5 Gbps, 10 Gbps (incl 5 Gbps), or 25 Gbps (including 10 Gbps and 5 Gbps) speeds. As well as, it will have a shadow DEV2G5 port module to support the lower speeds (10/100/1000/2500Mbps). When a port needs to operate at lower speed and the shadow DEV2G5 needs to be connected to its corresponding SerDes Not all interface modes are supported in this series, but will be added at a later stage.
