dcb: Add a subtool for the DCB PFC object
...
PFC, for "Priority-based Flow Control", allows configuration of priority
lossiness, and related toggles.
Add a dcb subtool to allow showing and tweaking of individual PFC
configuration options, and querying statistics. For example:
# dcb pfc show dev eni1np1
pfc-cap 8 macsec-bypass on delay 0
pg-pfc 0:off 1:on 2:off 3:off 4:off 5:off 6:off 7:on

dcb: Add a subtool for the DCB ETS object
...
ETS, for "Enhanced Transmission Selection", is a set of configurations that
permit configuration of mapping of priorities to traffic classes, traffic
selection algorithm to use per traffic class, bandwidth allocation, etc.
Add a dcb subtool to allow showing and tweaking of individual ETS
configuration options. For example:
# dcb ets show dev eni1np1
willing on ets_cap 8 cbs off

Add skeleton of a new tool, dcb
...
The Linux DCB interface allows configuration of a broad range of
hardware-specific attributes, such as TC scheduling, flow control, per-port
buffer configuration, TC rate, etc. Add a new tool to show that
configuration and tweak it.
DCB allows configuration of several objects, and possibly could expand to
pre-standard CEE interfaces. Therefore the tool itself is a lean shell that
dispatches to subtools each dedicated to one of the objects.
