From: Mohsin Bashir <[email protected]>
Add more net shaper selftest coverage for group operations and nested
node management.
The series first prepares shared cleanup and capability helpers, and
separates the basic netdev grouping coverage from the rate-limited
variant. It then adds tests for updating node shaper rates through both
.set and .group, discovering the supported nesting depth, deleting child
nodes and reparenting their leaves, moving queues between nodes, and
rejecting node reparenting.
Further patches broaden API coverage: exercising the full set of scalar
shaper attributes, rejecting invalid .set requests while leaving the
existing configuration intact, grouping leaves drawn from different
parents (which requires an explicit parent), and recursively cleaning up
nodes left empty.
The new tests use the capability helper to skip unsupported devices
instead of depending on earlier test ordering, size their queue
requirements from the number of TX queues exposed in sysfs, and register
cleanup for created shapers as soon as the operation succeeds.
