2023-02-03net: renesas: rswitch: Add "max-speed" handlingYoshihiro Shimoda1-3/+12
The previous code set the speed by the interface mode of PHY. Also this hardware has a restriction which cannot change the speed at runtime. To use other speed, add "max-speed" handling to set each port's speed if needed. Signed-off-by: Yoshihiro Shimoda <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2023-02-03net: renesas: rswitch: Add phy_power_{on,off}() callingYoshihiro Shimoda1-0/+5
Some Ethernet PHYs (like marvell10g) will decide the host interface mode by the media-side speed. So, the rswitch driver needs to initialize one of the Ethernet SERDES (r8a779f0-eth-serdes) ports after linked the Ethernet PHY up. The r8a779f0-eth-serdes driver has .init() for initializing all ports and .power_on() for initializing each port. So, add phy_power_{on,off} calling for it.

2023-02-03net: renesas: rswitch: Convert to phy_deviceYoshihiro Shimoda2-50/+62
Intended to set phy_device->host_interfaces by phylink in the future. But there is difficult to implement phylink properly, especially supporting the in-band mode on this driver because extra initialization is needed after linked the ethernet PHY up. So, convert to phy_device from phylink. Signed-off-by: Yoshihiro Shimoda <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2023-02-03net: phylink: move phy_device_free() to correctly release phy deviceClément Léger1-3/+2
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.

Conversion to gpiod API done in commit 468ba54bd616 ("fec: convert to gpio descriptor") clashed with gpiolib applying the same quirk to the reset GPIO polarity (introduced in commit b02c85c9458c). This results in the reset line being left active/device being left in reset state when reset line is "active low". Remove handling of 'phy-reset-active-high' property from the driver and rely on gpiolib to apply needed adjustments to avoid ending up with the double inversion/flipped logic.

2023-02-02drivers: net: turn on XDP featuresMarek Majtyka38-5/+154
A summary of the flags being set for various drivers is given below. Note that XDP_F_REDIRECT_TARGET and XDP_F_FRAG_TARGET are features that can be turned off and on at runtime. This means that these flags may be set and unset under RTNL lock protection by the driver. Hence, READ_ONCE must be used by code loading the flag value. Also, these flags are not used for synchronization against the availability of XDP resources on a device. It is merely a hint, and hence the read may race with the actual teardown of XDP resources on the device. This may change in the future, e.g. operations taking a reference on the XDP resources of the driver, and in turn inhibiting turning off this flag. However, for now, it can only be used as a hint to check whether device supports becoming a redirection target. Turn 'hw-offload' feature flag on for: - netronome (nfp) - netdevsim. Turn 'native' and 'zerocopy' features flags on for: - intel (i40e, ice, ixgbe, igc) - mellanox (mlx5). - stmmac - netronome (nfp) Turn 'native' features flags on for: - amazon (ena) - broadcom (bnxt) - freescale (dpaa, dpaa2, enetc) - funeth - intel (igb) - marvell (mvneta, mvpp2, octeontx2) - mellanox (mlx4) - mtk_eth_soc - qlogic (qede) - sfc - socionext (netsec) - ti (cpsw) - tap - tsnep - veth - xen - virtio_net.

The code expect the PHY to be in power down which is only true after reset. Allow changes of the SGMII parameters more than once. Only power down when reconfiguring to avoid bouncing the link when there's no reason to - based on code from Russell King. There are cases when the SGMII_PHYA_PWD register contains 0x9 which prevents SGMII from working. The SGMII still shows link but no traffic can flow.

This patch introduces 3 new functions implementing support for ethtool access to the CAN channel ID of all USB CAN network interfaces managed by the driver. With this patch, it is possible to read/write the CAN channel ID from/to the EEPROM via the ethtool interface. The CAN channel ID is a user-configurable device identifier that can be set individually for each CAN interface of a PEAK USB device. Depending on the device, the identifier has a length of 8 or 32 bit. The identifier is stored in the non-volatile memory of the device. The identifier of a CAN interface can be read/written as an 8 or 32 bit byte string in native (little-endian) byte order, where the length depends on the device type.

The so-called "device id" is a user-defined identifier value that can be set individually for each CAN interface of a PEAK USB device. Contrary to a static serial number, the value can be changed by the user.

2023-02-02can: rcar_canfd: Fix R-Car V3U CAN mode selectionGeert Uytterhoeven1-9/+10
When adding support for R-Car V3U, the Global FD Configuration register (CFDGFDCFG) and the Channel-specific CAN-FD Configuration Registers (CFDCmFDCFG) were mixed up. Use the correct register, and apply the selected CAN mode to all available channels. Annotate the corresponding register bits, to make it clear they do not exist on older variants.

For CRC transfers with size 1 it is more efficient to use the write_safe command instead of the write_crc command.

2023-02-02amd-xgbe: add support for rx-adaptationRaju Rangoju3-4/+211
The existing implementation for non-Autonegotiation 10G speed modes does not enable RX adaptation in the Driver and FW. The RX Equalization settings (AFE settings alone) are manually configured and the existing link-up sequence in the driver does not perform rx adaptation process as mentioned in the Synopsys databook. There's a customer request for 10G backplane mode without Auto-negotiation and for the DAC cables of more significant length that follow the non-Autonegotiation mode. These modes require PHY to perform RX Adaptation. The proposed logic adds the necessary changes to Yellow Carp devices to ensure seamless RX Adaptation for 10G-SFI (LONG DAC) and 10G-KR without AN (CL72 not present). The RX adaptation core algorithm is executed by firmware, however, to achieve that a new mailbox sub-command is required to be sent by the driver.

2023-02-02hv_netvsc: Fix missed pagebuf entries in netvsc_dma_map/unmap()Michael Kelley1-7/+2
netvsc_dma_map() and netvsc_dma_unmap() currently check the cp_partial flag and adjust the page_count so that pagebuf entries for the RNDIS portion of the message are skipped when it has already been copied into a send buffer. But this adjustment has already been made by code in netvsc_send(). The duplicate adjustment causes some pagebuf entries to not be mapped. In a normal VM, this doesn't break anything because the mapping doesn’t change the PFN. But in a Confidential VM, dma_map_single() does bounce buffering and provides a different PFN. Failing to do the mapping causes the wrong PFN to be passed to Hyper-V, and various errors ensue. Fix this by removing the duplicate adjustment in netvsc_dma_map() and netvsc_dma_unmap().
