====================
net: ENETC mqprio/taprio cleanup
Please excuse the increased patch set size compared to v4's 15 patches,
but Claudiu stirred up the pot :) when he pointed out that the mqprio
TXQ validation procedure is still incorrect, so I had to fix that, and
then do some consolidation work so that taprio doesn't duplicate
mqprio's bugs. Compared to v4, 3 patches are new and 1 was dropped for now
("net/sched: taprio: mask off bits in gate mask that exceed number of TCs"),
since there's not really much to gain from it. Since the previous patch
set has largely been reviewed, I hope that a delta overview will help
and make up for the large size.
v4->v5:
- new patches:
"[08/17] net/sched: mqprio: allow reverse TC:TXQ mappings"
"[11/17] net/sched: taprio: centralize mqprio qopt validation"
"[12/17] net/sched: refactor mqprio qopt reconstruction to a library function"
- changed patches worth revisiting:
"[09/17] net/sched: mqprio: allow offloading drivers to request queue
count validation"
v4 at:
https://patchwork.kernel.org/project/netdevbpf/cover/20230130173145.475943-1-vladimir.oltean@nxp.com/
v3->v4:
- adjusted patch 07/15 to not remove "#include <net/pkt_sched.h>" from
ti cpsw
https://patchwork.kernel.org/project/netdevbpf/cover/20230127001516.592984-1-vladimir.oltean@nxp.com/
v2->v3:
- move min_num_stack_tx_queues definition so it doesn't conflict with
the ethtool mm patches I haven't submitted yet for enetc (and also to
make use of a 4 byte hole)
- warn and mask off excess TCs in gate mask instead of failing
- finally CC qdisc maintainers
v2 at:
https://patchwork.kernel.org/project/netdevbpf/patch/20230126125308.1199404-16-vladimir.oltean@nxp.com/
v1->v2:
- patches 1->4 are new
- update some header inclusions in drivers
- fix typo (said "taprio" instead of "mqprio")
- better enetc mqprio error handling
- dynamically reconstruct mqprio configuration in taprio offload
- also let stmmac and tsnep use per-TXQ gate_mask
v1 (RFC) at:
https://patchwork.kernel.org/project/netdevbpf/cover/20230120141537.1350744-1-vladimir.oltean@nxp.com/
The main goal of this patch set is to make taprio pass the mqprio queue
configuration structure down to ndo_setup_tc() - patch 13/17. But mqprio
itself is not in the best shape currently, so there are some
consolidation patches on that as well.
Next, there are some consolidation patches in the enetc driver's
handling of TX queues and their traffic class assignment. Then, there is
a consolidation between the TX queue configuration for mqprio and
taprio.
Finally, there is a change in the meaning of the gate_mask passed by
taprio through ndo_setup_tc(). We introduce a capability through which
drivers can request the gate mask to be per TXQ. The default is changed
so that it is per TC.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
