Kunihiko Hayashi says: ==================== ave: fix the activation issues for some UniPhier SoCs This add the following stuffs to fix the activation issues and satisfy requirements for AVE ethernet driver implemented on some UniPhier SoCs. - Add support for additional necessary clocks and resets, because the kernel is stalled on Pro4 due to lack of them. - Check whether the SoC supports the specified phy-mode - Add DT property support indicating system controller that has the feature for configurating phy-mode including built-in phy on LD11. v1: https://www.spinics.net/lists/netdev/msg494904.html Changes since v1: - Add 'Reviewed-by' lines ==================== Signed-off-by:

This patch adds support for specifying system controller that configures phy-mode setting. According to the DT property "phy-mode", it's necessary to configure the controller, which is used to choose the settings of the MAC suitable, for example, mdio pin connections, internal clocks, and so on. Supported phy-modes are SoC-dependent. The driver allows phy-mode to set "internal" if the SoC has a built-in PHY, and {"mii", "rmii", "rgmii"} if the SoC supports each mode. So we have to check whether the phy-mode is valid or not. This adds the following features for each SoC: - check whether the SoC supports the specified phy-mode - configure the controller accroding to phy-mode The DT property accepts one argument to distinguish them for multiple MAC instances. ethernet@65000000 { ... socionext,syscon-phy-mode = <&soc_glue 0>; }; ethernet@65200000 { ... socionext,syscon-phy-mode = <&soc_glue 1>; }; Signed-off-by:Kunihiko Hayashi <hayashi.kunihiko@socionext.com> Signed-off-by:

When the link is becoming up for Pro4 SoC, the kernel is stalled due to some missing clocks and resets. The AVE block for Pro4 is connected to the GIO bus in the SoC. Without its clock/reset, the access to the AVE register makes the system stall. In the same way, another MAC clock for Giga-bit Connection and the PHY clock are also required for Pro4 to activate the Giga-bit feature and to recognize the PHY. To satisfy these requirements, this patch adds support for multiple clocks and resets, and adds the clock-names and reset-names to the binding because we need to distinguish clock/reset for the AVE main block and the others. Also, make the resets a required property. Currently, "reset is optional" relies on that the bootloader or firmware has deasserted the reset before booting the kernel. Drivers should work without such expectation. Fixes: 4c270b55 ("net: ethernet: socionext: add AVE ethernet driver") Suggested-by:

mdiobus_register will search for any mdiobus board info registered for the bus being registered. If found, it will probe devices on the bus. That device, if for example it is an ethernet switch, may then try to register an mdio bus. Thus we need to allow recursive calls to mdiobus_register. Holding the mdio_board_lock will cause a deadlock during this recursion. Release the lock and use list_for_each_entry_safe. Signed-off-by:

Michael Schmitz says: ==================== New network driver for Amiga X-Surf 100 (m68k) [This is a resend of my v3 series which was based on the wrong version and tree. Only substantial change is to Asix AX99796B PHY driver.] This patch series adds support for the Individual Computers X-Surf 100 network card for m68k Amiga, a network adapter based on the AX88796 chip set. The driver was originally written for kernel version 3.19 by Michael Karcher (see CC:), and adapted to 4.16+ for submission to netdev by me. Questions regarding motivation for some of the changes are probably best directed at Michael Karcher. The driver has been tested by Adrian <glaubitz@physik.fu-berlin.de> who will send his Tested-by tag separately. A few changes to the ax88796 driver were required: - to read the MAC address, some setup of the ax99796 chip must be done, - attach to the MII bus only on device open to allow module unloading, - allow to supersede ax_block_input/ax_block_output by card-specific optimized code, - use an optional interrupt status callback to allow easier sharing of the card interrupt, - set IRQF_SHARED if platform IRQ resource is marked shareable The Asix Electronix PHY used on the X-Surf 100 is buggy, and causes the software reset to hang if the previous command sent to the PHY was also a soft reset. This bug requires addition of a PHY driver for Asix PHYs to provide a fixed .soft_reset function, included in this series. Some additional cleanup: - do not attempt to free IRQ in ax_remove (complements 82533ad9), - clear platform drvdata on probe fail and module remove. Changes since v1: Raised in review by Andrew Lunn: - move MII code around to avoid need for forward declaration, - combine patches 2 and 7 to add cleanup in error path Changes since v2: - corrected authorship attribution to Michael Karcher Suggested by Geert Uytterhoeven: - use ei_local->reset_8390() instead of duplicating ax_reset_8390(), - use %pR to format struct resource pointers, - assign pdev and xs100 pointers in declaration, - don't split error messages, - change Kconfig logic to only require XSURF100 set on Amiga Suggested by Andrew Lunn: - add COMPILE_TEST to ax88796 Kconfig options, - use new Asix PHY driver for X-Surf 100 Suggested by Andrew Lunn/Finn Thain: - declare struct sk_buff in ax88796.h, - correct whitespace error in ax88796.h Changes since v3: - various checkpatch cleanup Andrew Lunn: - don't duplicate genphy_soft_reset in Asix PHY driver, just call genphy_soft_reset after writing zero to control register ==================== Signed-off-by:

This complements the fix in 82533ad9 ("net: ethernet: ax88796: don't call free_irq without request_irq first") that removed the free_irq call in the error path of probe, to also not call free_irq when remove is called to revert the effects of probe.

Andrew Lunn says: ==================== Modernize mdio-gpio This patchset is inspired by a previous version by Linus Walleij It reworks the mdio-gpio code to make use of gpio descriptors instead of gpio numbers. However compared to the previous version, it retains support for platform devices. It does however remove the platform_data header file. The needed GPIOs are now passed by making use of a gpiod lookup table. e.g: static struct gpiod_lookup_table zii_scu_mdio_gpiod_table = { .dev_id = "mdio-gpio.0", .table = { GPIO_LOOKUP_IDX("gpio_ich", 17, NULL, MDIO_GPIO_MDC, GPIO_ACTIVE_HIGH), GPIO_LOOKUP_IDX("gpio_ich", 2, NULL, MDIO_GPIO_MDIO, GPIO_ACTIVE_HIGH), GPIO_LOOKUP_IDX("gpio_ich", 21, NULL, MDIO_GPIO_MDO, GPIO_ACTIVE_LOW), }, }; ==================== Signed-off-by: -

David Ahern says: ==================== net/ipv6: followup to fib6_info change Followup to fib change for IPv6. First 2 patches rename fib6_info struct elements to match its name, and rename addrconf_dst_alloc to match what it returns. Patches 3-7 refactor the code to remove the need for fib6_idev reducing fib6_info by another 8 bytes to 200 bytes. Patch 8 fixes the gfp flags argument to addrconf_prefix_route in a couple of places. ==================== Signed-off-by: -

Eric noticed that __ipv6_ifa_notify is called under rcu_read_lock, so the gfp argument to addrconf_prefix_route can not be GFP_KERNEL. While scrubbing other calls I noticed addrconf_addr_gen has one place with GFP_ATOMIC that can be GFP_KERNEL.

Prior to 4832c30d ("net: ipv6: put host and anycast routes on device with address") host routes and anycast routes were installed with the device set to loopback (or VRF device once that feature was added). In the older code dst.dev was set to loopback (needed for packet tx) and rt6i_idev was used to denote the actual interface. Commit 4832c30d changed the code to have dst.dev pointing to the real device with the switch to lo or vrf device done on dst clones. As a consequence of this change ip6_route_get_saddr can just pass the nexthop device to ipv6_dev_get_saddr. Signed-off-by:

After working on IP defragmentation lately, I found that some large packets defeat CHECKSUM_COMPLETE optimization because of NIC adding zero paddings on the last (small) fragment. While removing the padding with pskb_trim_rcsum(), we set skb->ip_summed to CHECKSUM_NONE, forcing a full csum validation, even if all prior fragments had CHECKSUM_COMPLETE set. We can instead compute the checksum of the part we are trimming, usually smaller than the part we keep. Signed-off-by:
