Subject: [PATCH v6 net-next 02/15] netlink: spec: add shaper YAML spec
Define the user-space visible interface to query, configure and delete
network shapers via yaml definition.
Add dummy implementations for the relevant NL callbacks.
set() and delete() operations touch a single shaper creating/updating or
deleting it.
The group() operation creates a shaper's group, nesting multiple input
shapers under the specified output shaper.
Signed-off-by: Paolo Abeni <pabeni@...hat.com>
---
v5 -> v6:
- moved back ifindex out of binding attr, drop the latter
- restrict leaves attributes to scheduling-related ones
v4 -> v5:
- moved ifindex under the binding attr
- moved id, scope to new attr set
- rename 'root' as 'node'
- deleted unused 'info' subset
- a lot of doc update and fixup
- removed empty black line at MAKEFILE eof
v3 -> v4:
- spec file rename
- always use '@' for references
- detached scope -> node scope
- inputs/output -> leaves/root
- deduplicate leaves/root policy
- get/dump/group return ifindex, too
- added some general introduction to the doc
RFC v1 -> RFC v2:
- u64 -> uint
- net_shapers -> net-shapers
- documented all the attributes
- dropped [ admin-perm ] for get() op
- group op
- set/delete touch a single shaper

+ Networking HW rate limiting configuration.
+
+ This API allows configuring HW shapers available on the network
+ devices at different levels (queues, network device) and allows
+ arbitrary manipulation of the scheduling tree of the involved
+ shapers.
+
+ Each @shaper is identified within the given device, by an @handle,
+ comprising both a @scope and an @id.
+
+ Depending on the @scope value, the shapers are attached to specific
+ HW objects (queues, devices) or, for @node scope, represent a
+ scheduling group, that can be placed in an arbitrary location of
+ the scheduling tree.
+
+ Shapers can be created with two different operations: the @set
+ operation, to create and update a single "attached" shaper, and
+ the @group operation, to create and update a scheduling
+ group. Only the @group operation can create @node scope shapers
+
+ Existing shapers can be deleted /reset via the @delete operation.
+
+ The user can query the running configuration via the @get operation.
