The existing method of reserving unicast filter count leads to wasted
MCAM entries if the functionality is not used or fewer entries are used.
Furthermore, the amount of MCAM entries differs amongst Octeon SoCs.
We implemented a means to adjust the UC filter count via devlink,
allowing for better use of MCAM entries across Netdev apps.
commands:
To get the current unicast filter count
# devlink dev param show pci/0002:02:00.0 name unicast_filter_count
To change/set the unicast filter count
# devlink dev param set pci/0002:02:00.0 name unicast_filter_count
value 5 cmode runtime

New drivers were prevented from adding ndo_set_vf_* callbacks
over the last few years. This was expected to result in broader
switchdev adoption, but seems to have had little effect.
Based on recent netdev meeting there is broad support for allowing
adding those ops.
There is a problem with the current API supporting a limited number
of VFs (100+, which is less than some modern HW supports).
We can try to solve it by adding similar functionality on devlink
ports, but that'd be another API variation to maintain.
So a netlink attribute reshuffling is a more likely outcome.
Document the guidance, make it clear that the API is frozen.

The KSZ9477 allows HSR in-HW offloading for any of two selected ports.
This patch adds check if one tries to use more than two ports with
HSR offloading enabled.
The problem is with RedBox configuration (HSR-SAN) - when configuring:
ip link add name hsr0 type hsr slave1 lan1 slave2 lan2 interlink lan3 \
supervision 45 version 1
The lan1 (port0) and lan2 (port1) are correctly configured as ports, which
can use HSR offloading on ksz9477.
However, when we do already have two bits set in hsr_ports, we need to
return (-ENOTSUPP), so the interlink port (lan3) would be used with
SW based HSR RedBox support.
Otherwise, I do see some strange network behavior, as some HSR frames are
visible on non-HSR network and vice versa.
This causes the switch connected to interlink port (lan3) to drop frames
and no communication is possible.
Moreover, conceptually - the interlink (i.e. HSR-SAN port - lan3/port2)
shall be only supported in software as it is also possible to use ksz9477
with only SW based HSR (i.e. port0/1 -> hsr0 with offloading, port2 ->
HSR-SAN/interlink, port4/5 -> hsr1 with SW based HSR).

bnxt_en: implement netdev_queue_mgmt_ops
Implement netdev_queue_mgmt_ops for bnxt added in [1]. This will be used
in the io_uring ZC Rx patchset to configure queues with a custom page
pool w/ a special memory provider for zero copy support.
The first two patches prep the driver, while the final patch adds the
implementation.
Any arbitrary Rx queue can be reset without affecting other queues. V2
and prior of this patchset was thought to only support resetting queues
not in the main RSS context. Upon further testing I realised moving
queues out and calling bnxt_hwrm_vnic_update() wasn't necessary.
I didn't include the netdev core API using this netdev_queue_mgmt_ops
because Mina is adding it in his devmem TCP series [2]. But I'm happy to
include it if folks want to include a user with this series.
I tested this series on BCM957504-N1100FY4 with FW 229.1.123.0. I
manually injected failures at all the places that can return an errno
and confirmed that the device/queue is never left in a broken state.

Implement netdev_queue_mgmt_ops for bnxt added in [1].
Two bnxt_rx_ring_info structs are allocated to hold the new/old queue
memory. Queue memory is copied from/to the main bp->rx_ring[idx]
bnxt_rx_ring_info.
Queue memory is pre-allocated in bnxt_queue_mem_alloc() into a clone,
and then copied into bp->rx_ring[idx] in bnxt_queue_mem_start().
Similarly, when bp->rx_ring[idx] is stopped its queue memory is copied
into a clone, and then freed later in bnxt_queue_mem_free().
I tested this patchset with netdev_rx_queue_restart(), including
inducing errors in all places that returns an error code. In all cases,
the queue is left in a good working state.
Rx queues are created/destroyed using bnxt_hwrm_rx_ring_alloc() and
bnxt_hwrm_rx_ring_free(), which issue HWRM_RING_ALLOC and HWRM_RING_FREE
commands respectively to the firmware. By the time a HWRM_RING_FREE
response is received, there won't be any more completions from that
queue.

ionic: rework fix for doorbell miss
A latency test in a scaled out setting (many VMs with many queues)
has uncovered an issue with our missed doorbell fix from
commit b69585bfce ("ionic: missed doorbell workaround")
As a refresher, the Elba ASIC has an issue where once in a blue
moon it might miss/drop a queue doorbell notification from
the driver. This can result in Tx timeouts and potential Rx
buffer misses.
The basic problem with the original solution is that
we're delaying things with a timer for every single queue,
periodically using mod_timer() to reset to reset the alarm, and
mod_timer() becomes a more and more expensive thing as there
are more and more VFs and queues each with their own timer.
A ping-pong latency test tends to exacerbate the effect such
that every napi is doing a mod_timer() in every cycle.
An alternative has been worked out to replace this using
periodic workqueue items outside the napi cycle to request a
napi_schedule driven by a single delayed-workqueue per device
rather than a timer for every queue. Also, now that newer
firmware is actually reporting its ASIC type, we can restrict
this to the appropriate chip.
The testing scenario used 128 VFs in UP state, 16 queues per
VF, and latency tests were done using TCP_RR with adaptive
interrupt coalescing enabled, running on 1 VF. We would see
99th percentile latencies of up to 900us range, with some max
fliers as much as 4ms.
With these fixes the 99th percentile latencies are typically well
under 50us with the occasional max under 500us.

Currently the driver either sets the initial interrupt affinity for its
adminq and tx/rx queues on probe or resets it on various
down/up/reconfigure flows. If any user and/or user process
(i.e. irqbalance) changes IRQ affinity for any of the driver's interrupts
that will be reset to driver defaults whenever any down/up/reconfigure
operation happens. This is incorrect and is fixed by making 2 changes:
1. Allocate an array of cpumasks that's only allocated on probe and
destroyed on remove.
2. Update the cpumask(s) for interrupts that are in use by registering
for affinity notifiers.

mlxsw: Use page pool for Rx buffers allocation
Amit Cohen writes:
After using NAPI to process events from hardware, the next step is to
use page pool for Rx buffers allocation, which is also enhances
performance.
To simplify this change, first use page pool to allocate one continuous
buffer for each packet, later memory consumption can be improved by using
fragmented buffers.
This set significantly enhances mlxsw driver performance, CPU can handle
about 370% of the packets per second it previously handled.
The next planned improvement is using XDP to optimize telemetry.
Patch set overview:
Patches #1-#2 are small preparations for page pool usage
Patch #3 initializes page pool, but do not use it
Patch #4 converts the driver to use page pool for buffers allocations
Patch #5 is an optimization for buffer access
Patch #6 cleans up an unused structure
Patch #7 uses napi_consume_skb() as part of Tx completion
