* rtnetlink: Add native SR-IOV VF statusKevin Bowling2026-09-062-0/+150
| | | | | | | | | | | | | | | | | | | | | | Add a transport neutral kernel snapshot for NIC-specific SR-IOV VF status and an optional iflib provider method. Providers gather state under driver defined synchronization. Honor RTEXT_FILTER_VF on RTM_GETLINK requests and encode the status as native typed route Netlink attributes. Represent VFs, driver namespaces, and namespace fields as directly repeated nested attributes. Presence masks in consumers can distinguish omission from false or zero. Drivers may add custom status under stable, versioned namespaces. The named, typed representation lets generic transports and consumers carry or display fields without knowing their driver-specific schemas, while the driver retains ownership of their names and meanings. Document the ABI and add parser and RTM_GETLINK coverage.

* rtnetlink: Report SR-IOV VF statusKevin Bowling2026-08-092-0/+145
| | | | | | | | | | | | | | | | Honor RTEXT_FILTER_VF on RTM_GETLINK requests and expose the versioned SR-IOV VF status through typed nested FreeBSD attributes. Report IFLA_NUM_VF with a successful requested query and preserve per-provider errors in the status container. Map the common nvlist schema to native integer, boolean, string, and binary attributes. Carry namespaced driver extensions as packed versioned nvlists so adding a driver-specific field does not expand the common netlink ABI. Add SNL parsers, parser verification, a constructed nested-status test, and an RTM_GETLINK test for an interface without SR-IOV support. Document the query contract and every attribute.

| | | | | | | | | | | | | | | | | | | | This changes intends to reduce the bar to the kernel unit-testing by introducing a new kernel-testing framework ("ktest") based on Netlink, loadable test modules and python test suite integration. This framework provides the following features: * Integration to the FreeBSD test suite * Automatic test discovery * Automatic test module loading * Minimal boiler-plate code in both kernel and userland * Passing any metadata to the test * Convenient environment pre-setup using python testing framework * Streaming messages from the kernel to the userland * Running tests in the dedicated taskqueues * Skipping or parametrizing tests Differential Revision: https://reviews.freebsd.org/D39385 MFC after: 2 weeks
