Petr Machata	ef15b07601	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 tc-bw 0:0 1:0 2:0 3:0 4:100 5:0 6:0 7:0 pg-bw 0:0 1:0 2:0 3:0 4:0 5:0 6:0 7:0 tc-tsa 0:strict 1:strict 2:strict 3:strict 4:ets 5:strict 6:strict 7:strict prio-tc 0:1 1:3 2:5 3:0 4:0 5:0 6:0 7:0 reco-tc-bw 0:0 1:0 2:0 3:0 4:0 5:0 6:0 7:0 reco-tc-tsa 0:strict 1:strict 2:strict 3:strict 4:strict 5:strict 6:strict 7:strict reco-prio-tc 0:0 1:0 2:0 3:0 4:0 5:0 6:0 7:0 Signed-off-by: Petr Machata <me@pmachata.org> Signed-off-by: David Ahern <dsahern@gmail.com>	2020-11-13 19:43:19 -07:00
Petr Machata	67033d1c1c	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.
