Subject: [PATCH v4 net-next 00/15] ENETC mqprio/taprio cleanup
Please excuse the spam, I had failed to compile-test CONFIG_TI_CPSW with
the previous version. Not deleting an #include is the only delta between
v3 and v4.
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 12/15. 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's driver
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.
