[PATCH iproute2-next v2 0/6] netshaper: Extend netshaper support

[Mohsin Bashir <mohsin.bashr@gmail.com>]

From: Mohsin Bashir <hmohsin@meta.com>

This series extends the netshaper CLI with missing parameter support
and adds the group command for building scheduling hierarchies.

The existing netshaper tool only supports setting bw-max on individual
shapers. This series adds the remaining shaper attributes (bw-min,
weight) needed for TX scheduling, and introduces the group command
which ties leaf shapers to a parent node in a single operation.

Changelog:

  Patch 1:
  - parse_scope(): use loop over net_shaper_scope_names[]
    instead of hardcoded string comparisons
  - parse_rate(): replace magic number 8 with BITS_PER_BYTE

  Patch 2:
  - Add has_bw_min/has_bw_max/has_weight booleans so zero-valued
    attrs are correctly sent
  - Add has_handle_id; only send handle id when explicitly provided
  - Keep node id required in do_cmd(); only netdev scope has
    optional id
  - Only emit rate/weight attrs for set command, not show/delete
  - Validate ll_name_to_index() return, error on unknown device

  Patch 3:
  - Use print_rate() for bandwidth display instead of truncating
    to integer Mbps

  Patch 4 (new):
  - Extract struct shaper_args and parse_shaper_arg() helper to
    share argument parsing between do_cmd() and do_group()

  Patch 5 (was v1 patch 5, v1 patch 4 dropped):
  - Reuse parse_shaper_arg() for common argument parsing
  - Validate group handle and parent scopes are node or netdev
  - Require parent id when parent scope is node
  - Fold optional node handle id into do_group() only
  - Define NET_SHAPER_MAX_LEAVES (256) for leaves array size

  Patch 6:
  - Document node id as required for set/show/delete, optional
    only for group
  - Add author to man page
