As Stephen Hemminger mentioned on the last submission the new_json_obj
function is always called with fp == stdout, so right now, there's no
need of this extra argument.
The background for the rework is the following:

The Credit Based Shaper (CBS) queueing discipline allows bandwidth
reservation with sub-milisecond precision. It is defined by the
802.1Q-2014 specification (section 8.6.8.2 and Annex L).
The syntax is:
tc qdisc add dev DEV parent NODE cbs locredit
hicredit sendslope
Export the API necessary for configuring the CBS shaper (implemented
in the next patch) via the tc tool.

Hi,
Changes from the RFC:
- Fixed comments from Henrik Austad;
- Simplified the Qdisc, using the generic implementation of callbacks
where possible;
- Small refactor on the driver (igb) code;
This patchset is a proposal of how the Traffic Control subsystem can
be used to offload the configu

This patch adds support for Credit-Based Shaper (CBS) qdisc offload
from Traffic Control system. This support enable us to leverage the
Forwarding and Queuing for Time-Sensitive Streams (FQTSS) features
from Intel i210 Ethernet Controller. FQTSS is the former 802.1Qav

This queueing discipline implements the shaper algorithm defined by
the 802.1Q-2014 Section 8.6.8.2 and detailed in Annex L.
It's primary usage is to apply some bandwidth reservation to user
defined traffic classes, which are mapped to different queues via the
mqprio qdisc.
Initially, it only sup

Ah, twice patch 6. Not good.
I will wait for a few days for comments, and then repost without the
duplication.

The software bridge needs to know if a packet has already been bridged
by hardware offload to ports in the same hardware offload, in order
that it does not re-flood them, causing duplicates. This is
particularly true for broadcast and multicast traffic which the host
has requested.
By setting offl
By default, the switch does not flood broadcast frames. Instead the
broadcast address is unknown in the ATU, so the frame gets forwarded
out the cpu port. The software bridge then floods it back to the
individual switch ports which are members of the bridge.
Add an ATU entry in the switch so that
SWITCHDEV_ATTR_ID_PORT_PARENT_ID is used by the software bridge when
determining which ports to flood a packet out. If the packet
originated from a switch, it assumes the switch has already flooded
the packet out the switches ports, so the bridge should not flood the
packet itself out switch ports.
This function is going to be needed by a soon to be added new
function. Move it earlier so we can avoid a forward declaration.
No code changes.
