[PATCH iproute2-next 0/4] dpll: add client-side filtering

This series fixes a parsing bug in dpll pin id-get and adds
client-side filtering support for dpll device show and pin show
commands.

Patch 1 fixes a bug where "dpll pin id-get type gnss" would read
the keyword "type" as the enum value instead of the actual type.

Patches 2-3 add client-side filtering for device show and pin show.
Users can filter output by various attributes (module-name, clock-id,
type, etc.) with AND semantics. Kernel-side dump filtering for dpll
is not yet available, so all filtering is done in userspace.

Patch 4 replaces the non-functional server-side "device" filter in
pin show (kernel ignores DPLL_A_ID in pin dump requests) with
client-side parent-device and parent-pin filtering that checks
nested multi-attrs. The argument is renamed from "device" to
"parent-device" to reflect the actual semantics.

Each patch includes corresponding man page and bash completion
updates.
