2022-09-06ice: Allow operation with reduced device MSI-XTony Nguyen
The driver currently takes an all or nothing approach for device MSI-X vectors. Meaning if it does not get its full allocation, it will fail and not load. There is no reason it can't work with a reduced number of MSI-X vectors. Take a similar approach as commit 741106f7bd8d ("ice: Improve MSI-X fallback logic") and, instead, adjust the MSI-X request to make use of what is available.

2022-09-06can: gs_usb: add RX and TX hardware timestamp supportJohn Whittington
Add support for hardware timestamps, if the firmware includes it as a feature via the GS_CAN_FEATURE_HW_TIMESTAMP flag. Check for this feature during probe, extend the RX expected length if it is and enable it during open. The struct classic_can_ts and struct canfd_ts are extended to include the µs timestamp following data as defined in the firmware. The timestamp is then captured and set using skb_hwtstamps() on each RX and TX. The frame µs timestamp is provided from a 32 bit 1 MHz timer which rolls over every 4294 seconds, so a cyclecounter, timecounter, and delayed worker are used to convert the timer into a proper ns timestamp - same implementation as commit efd8d98dfb900 ("can: mcp251xfd: add HW timestamp infrastructure"). Hardware timestamps are added to capabilities as commit b1f6b93e678f ("can: mcp251xfd: advertise timestamping capabilities and add ioctl support").

2022-09-05net: phy: Add 1000BASE-KX interface modeSean Anderson
Add 1000BASE-KX interface mode. This 1G backplane ethernet as described in clause 70. Clause 73 autonegotiation is mandatory, and only full duplex operation is supported. Although at the PMA level this interface mode is identical to 1000BASE-X, it uses a different form of in-band autonegation. This justifies a separate interface mode, since the interface mode (along with the MLO_AN_* autonegotiation mode) sets the type of autonegotiation which will be used on a link. This results in more than just electrical differences between the link modes. With regard to 1000BASE-X, 1000BASE-KX holds a similar position to SGMII: same signaling, but different autonegotiation. PCS drivers (which typically handle in-band autonegotiation) may only support 1000BASE-X, and not 1000BASE-KX. Similarly, the phy mode is used to configure serdes phys with phy_set_mode_ext. Due to the different electrical standards (SFI or XFI vs Clause 70), they will likely want to use different configuration.

2022-09-05net: dpaa: Adjust queue depth on rate changeSean Anderson
Instead of setting the queue depth once during probe, adjust it on the fly whenever we configure the link.

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.

We don't need to remap the base address from the resource twice (once in mac_probe() and again in set_fman_mac_params()).

While we're at it, use platform_get_mem_or_io and devm_request_resource to map the resource. I think this is the more "correct" way to do things here, since we use the pdev resource, instead of creating a new one. It's still a bit tricky, since we need to ensure that the resource is a child of the fman region when it gets requested.

2022-09-05net: mvpp2: debugfs: fix memory leak when using debugfs_lookup()Greg Kroah-Hartman
When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. Fix this up to be much simpler logic and only create the root debugfs directory once when the driver is first accessed. That resolves the memory leak and makes things more obvious as to what the intent is. Cc: Marcin Wojtas <mw@semihalf.com> Cc: Russell King <linux@armlinux.org.uk> Cc: "David S.

This patch doesn't change any functionality, but move one function to mlx5_ib because it is not used by mlx5_core. The actual fix is in the next patch.

2022-09-05net: dsa: microchip: lan937x: add interrupt support for port phy linkArun Ramadoss
This patch enables the interrupts for internal phy link detection for LAN937x. The interrupt enable bits are active low. There is global interrupt mask for each port. And each port has the individual interrupt mask for TAS. QCI, SGMII, PTP, PHY and ACL. The first level of interrupt domain is registered for global port interrupt and second level of interrupt domain for the individual port interrupts. The phy interrupt is enabled in the lan937x_mdio_register function. Interrupt from which port is raised will be detected based on the interrupt host data.

In the lan937x_reset_switch(), it masks all the switch and port registers. In the Global_Int_status register, POR ready bit is write 1 to clear bit and all other bits are read only. So, this patch clear the por_ready_int status bit by writing 1. Signed-off-by: Arun Ramadoss <arun.ramadoss@microchip.com> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

2022-09-05net: dsa: microchip: add reference to ksz_device inside the ksz_portArun Ramadoss
struct ksz_port doesn't have reference to ksz_device as of now. In order to find out from which port interrupt has triggered, we need to pass the struct ksz_port as a host data. When the interrupt is triggered, we can get the port from which interrupt triggered, but to identify it is phy interrupt we have to read status register. The regmap structure for accessing the device register is present in the ksz_device struct. To access the ksz_device from the ksz_port, the reference is added to it with port number as well.
