Add support for scanning PHY in PHY package nodes. PHY packages nodes are just container for actual PHY on the MDIO bus. Their PHY address defined in the PHY package node are absolute and reflect the address on the MDIO bus. mdio_bus.c and of_mdio.c is updated to now support and parse also PHY package subnode by checking if the node name match "ethernet-phy-package". As PHY package reg is mandatory and each PHY in the PHY package must have a reg, every invalid PHY Package node is ignored and will be skipped by the autoscan fallback. Signed-off-by:

Document ethernet PHY package nodes used to describe PHY shipped in bundle of 2-5 PHY. The special node describe a container of PHY that share common properties. This is a generic schema and PHY package should create specialized version with the required additional shared properties. Example are PHY packages that have some regs only in one PHY of the package and will affect every other PHY in the package, for example related to PHY interface mode calibration or global PHY mode selection. The PHY package node MUST declare the base address used by the PHY driver for global configuration by calculating the offsets of the global PHY based on the base address of the PHY package. Each reg of the PHYs defined in the PHY package node is absolute and describe the real address of the Ethernet PHY on the bus. Signed-off-by:

udpgso regression test configures routing and device MTU directly through uAPI (Netlink, ioctl) to do its job. While there is nothing wrong with it, it takes more effort than doing it from shell. Looking forward, we would like to extend the udpgso regression tests to cover the EIO corner case [1], once it gets addressed. That will require a dummy device and device feature manipulation to set it up. Which means more Netlink code. So, in preparation, pull out network configuration into the shell script part of the test, so it is easily extendable in the future. Also, because it now easy to setup routing, add a second local IPv6 address. Because the second address is not managed by the kernel, we can "replace" the corresponding local route with a reduced-MTU one. This unblocks the disabled "ipv6 connected" test case. Add a similar setup for IPv4 for symmetry. [1] https://lore.kernel.org/netdev/87jzqsld6q.fsf@cloudflare.com/Reviewed-by:

While individual filter structures are allocated as needed, there is an array to keep track of the software filter IDs that we allocate ahead of time. Rather than relying on a fixed maximum filter count to allocate this array, get the maximum from the firmware when available. Move these filter related maximum counts queried from the firmware to the bnxt_hw_resc struct. If the firmware is not providing these maximum counts, fall back to the hard-coded constant.

Merge netdev bits of io_uring busy polling support. Jens Axboe says: ==================== io_uring: add napi busy polling support I finally got around to testing this patchset in its current form, and results look fine to me. It Works. Using the basic ping/pong test that's part of the liburing addition, without enabling NAPI I get: Stock settings, no NAPI, 100k packets: rtt(us) min/avg/max/mdev = 31.730/37.006/87.960/0.497 and with -t10 -b enabled: rtt(us) min/avg/max/mdev = 23.250/29.795/63.511/1.203 In short, this patchset enables per io_uring NAPI enablement, rather than need to enable that globally. This allows targeted NAPI usage with io_uring.

On early detection of wwan device in fastboot mode, driver sets up CLDMA0 HW tx/rx queues for raw data transfer and then create fastboot port to userspace. Application can use this port to flash firmware and collect core dump by fastboot protocol commands. E.g., flash firmware through fastboot port: - "download:%08x": write data to memory with the download size. - "flash:%s": write the previously downloaded image to the named partition. - "reboot": reboot the device.

Store a formatted string for userdata that will be appended to netconsole messages. The string has a capacity of 4KB, as calculated by the userdatum entry length of 256 bytes and a max of 16 userdata entries. Update the stored netconsole_target->userdata_complete string with the new formatted userdata values when a userdatum is created, edited, or removed. Each userdata entry contains a trailing newline, which will be formatted as such in netconsole messages:: 6.7.0-rc8-virtme,12,500,1646292204,-;test release=foo something=bar 6.7.0-rc8-virtme,12,500,1646292204,-;another test release=foo something=bar Enforcement of MAX_USERDATA_ITEMS is done in userdatum_make_item; update_userdata will not check for this case but will skip any userdata children over the limit of MAX_USERDATA_ITEMs. If a userdata entry/dir is created but no value is provided, that entry will be skipped. This is in part because update_userdata() can't be called in userdatum_make_item() since the item will not have been added to the userdata config_group children yet. To preserve the experience of adding an empty userdata that doesn't show up in the netconsole messages, purposefully skip empty userdata items even when update_userdata() can be called.

Create configfs machinery for netconsole userdata appending, which depends on CONFIG_NETCONSOLE_DYNAMIC (for configfs interface). Add a userdata config_group to netconsole_target for managing userdata entries as a tree under the netconsole configfs subsystem. Directory names created under the userdata directory become userdatum keys; the userdatum value is the content of the value file. Include the minimum-viable-changes for userdata configfs config_group. init_target_config_group() ties in the complete configfs machinery to avoid unused func/variable errors during build. Initializing the netconsole_target->group is moved to init_target_config_group, which will also init and add the userdata config_group. Each userdatum entry has a limit of 256 bytes (54 for the key/directory, 200 for the value, and 2 for '=' and '\n' characters), which is enforced by the configfs functions for updating the userdata config_group. When a new netconsole_target is created, initialize the userdata config_group and add it as a default group for netconsole_target config_group, allowing the userdata configfs sub-tree to be presented in the netconsole configfs tree under the userdata directory.
