Commit 4dfb9982 ("tsn: Fix build.") fixed compilation with const dev_addr. In tsnep_netdev_set_mac_address() the call of ether_addr_copy() was replaced with dev_set_mac_address(), which calls ndo_set_mac_address(). This results in an endless recursive loop because ndo_set_mac_address is set to tsnep_netdev_set_mac_address. Call eth_hw_addr_set() instead of dev_set_mac_address() in ndo_set_mac_address()/tsnep_netdev_set_mac_address() to copy the address as intended.

Ansuel Smith says: ==================== Add mirror and LAG support to qca8k With the continue of adding 'Multiple feature to qca8k' The switch supports mirror mode and LAG. In mirror mode a port is set as mirror and other port are configured to both igress or egress mode. With no port configured for mirror, the mirror port is disabled and reverted to normal port. The switch supports max 4 LAG with 4 different member max. Current supported mode is Hash mode in both L2 or L2+3 mode. There is a problematic implementation for the hash mode where with multiple LAG configured, someone has to remove them to change the hash mode as it's global. When a member of the LAG is disconnected, the traffic is redirected to the other port. Some warning are present from checkpatch but can't really be fixed as it would result in making the regs less readable. (They really did their best with the LAG reg logic and complexity) ==================== Signed-off-by: -

Add LAG support to this switch. In Documentation this is described as trunk mode. A max of 4 LAGs are supported and each can support up to 4 port. The current tx mode supported is Hash mode with both L2 and L2+3 mode. When no port are present in the trunk, the trunk is disabled in the switch. When a port is disconnected, the traffic is redirected to the other available port. The hash mode is global and each LAG require to have the same hash mode set. To change the hash mode when multiple LAG are configured, it's required to remove each LAG and set the desired hash mode to the last. An error is printed when it's asked to set a not supported hadh mode. Signed-off-by:

This change adds a MCTP Serial transport binding, as defined by DMTF specificiation DSP0253 - "MCTP Serial Transport Binding". This is implemented as a new serial line discipline, and can be attached to arbitrary tty devices. From the Kconfig description: This driver provides an MCTP-over-serial interface, through a serial line-discipline, as defined by DMTF specification "DSP0253 - MCTP Serial Transport Binding". By attaching the ldisc to a serial device, we get a new net device to transport MCTP packets. This allows communication with external MCTP endpoints which use serial as their transport. It can also be used as an easy way to provide MCTP connectivity between virtual machines, by forwarding data between simple virtual serial devices. Say y here if you need to connect to MCTP endpoints over serial. To compile as a module, use m; the module will be called mctp-serial. Once the N_MCTP line discipline is set [using ioctl(TCIOSETD)], we get a new netdev suitable for MCTP communication. The 'mctp' utility[1] provides a simple wrapper for this ioctl, using 'link serial <device>': # mctp link serial /dev/ttyS0 & # mctp link dev lo index 1 address 0x00:00:00:00:00:00 net 1 mtu 65536 up dev mctpserial0 index 5 address 0x(no-addr) net 1 mtu 68 down [1]: https://github.com/CodeConstruct/mctpSigned-off-by:

Danielle Ratson authored
On an arm64 platform with the Spectrum ASIC, after loading and executing a new kernel via kexec, the following trace [1] is observed. This seems to be caused by the fact that the device is not properly shutdown before executing the new kernel. Fix this by implementing a shutdown method which mirrors the remove method, as recommended by the kexec maintainer [2][3].

Ansuel Smith says: ==================== Multiple cleanup and feature for qca8k This is a reduced version of the old massive series. Refer to the changelog to know what is removed from this. We clean and convert the driver to GENMASK FIELD_PREP to clean multiple use of various naming scheme. (example we have a mix of _MASK, _S _M, and various name) The idea is to ""simplify"" and remove some shift and data handling by using FIELD API. The patch contains various checkpatch warning and are ignored to not create more mess in the header file. (fixing the too long line warning would results in regs definition less readable) We conver the driver to regmap API as ipq40xx SoC is based on the same reg structure and we need to generilize the read/write access to split the driver to commond and specific code. The conversion to regmap is NOT done for the read/write/rmw operation, the function are reworked to use the regmap helper instead. This is done to keep the patch delta low but will come sooner or later when the code will be split. Any new feature will directly use the regmap helper and the reg set/clear and the busy wait function are migrated to regmap helper as the use of these function is low. We also add a minor patch for MIB counter as qca8337 is missing 2 extra counter, support for mdb and ageing settings. v3: - Try to reduce regmap conversion patch v2: - Move regmap init to sw_probe instead of moving switch id check. - Removed LAGs, mirror extra features will come later in another smaller series. - Squash 2 ageing patch - Add more description about the regmap patch - Rework mdb patch to do operation under the same lock ==================== Signed-off-by: -

Add support for mdb add/del function. The ARL table is used to insert the rule. The rule will be searched, deleted and reinserted with the port mask updated. The function will check if the rule has to be updated or insert directly with no deletion of the old rule. If every port is removed from the port mask, the rule is removed. The rule is set STATIC in the ARL table (aka it doesn't age) to not be flushed by fast age function. Signed-off-by:

Convert any qca8k set/clear/pool to regmap helper and add missing config to regmap_config struct. Read/write/rmw operation are reworked to use the regmap helper internally to keep the delta of this patch low. These additional function will then be dropped when the code split will be proposed. Ipq40xx SoC have the internal switch based on the qca8k regmap but use mmio for read/write/rmw operation instead of mdio. In preparation for the support of this internal switch, convert the driver to regmap API to later split the driver to common and specific code. The overhead introduced by the use of regamp API is marginal as the internal mdio will bypass it by using its direct access and regmap will be used only by configuration functions or fdb access.

This patch brings in support for device trace collection. It implements relayfs interface for pushing device trace from kernel space to user space. Driver gets the debugfs base directory associated to WWAN Device and creates trace_control and trace debugfs for device tracing. Both trace_control & trace debugfs are created under /sys/kernel/debug/wwan/wwan0/. In order to collect device trace on trace0 interface, user need to write 1 to trace_ctl interface. Signed-off-by:

This patch set brings in a common debugfs base directory i.e. /sys/kernel/debugfs/wwan/ in WWAN Subsystem for a WWAN device instance. So that it avoids driver polluting debugfs root with unrelated directories & possible name collusion. Having a common debugfs base directory for WWAN drivers eases user to match control devices with debugfs entries. WWAN Subsystem creates dentry (/sys/kernel/debugfs/wwan) on module load & removes dentry on module unload. When driver registers a new wwan device, dentry (wwanX) is created for WWAN device instance & on driver unregister dentry is removed. New API is introduced to return the wwan device instance dentry so that driver can create debugfs entries under it. Signed-off-by:

Commit 4904b6ea ("net: phy: phylink: Use PHY device interface if N/A") introduced handling for the phy interface mode where this is not known at phylink creation time. This was never added to the OF/fwnode paths, but is necessary when the phy is present in DT, but the phy-mode is not specified. Add this handling. Signed-off-by:
