Commit c685c69fba71 ("ixgbe: don't do any AF_XDP zero-copy transmit if
netif is not OK") addressed the ring transient state when
MEM_TYPE_XSK_BUFF_POOL was being configured which in turn caused the
interface to through down/up. Maurice reported that when carrier is not
ok and xsk_pool is present on ring pair, ksoftirqd will consume 100% CPU
cycles due to the constant NAPI rescheduling as ixgbe_poll() states that
there is still some work to be done.
To fix this, do not set work_done to false for a !netif_carrier_ok().

In order for the Felix DSA driver to be able to turn on/off flooding
towards its CPU port, we need to redirect calls on the NPI port to
actually act upon the index in the analyzer block that corresponds to
the CPU port module. This was never necessary until now because DSA
(or the bridge) never called ocelot_port_bridge_flags() for the NPI
port.

Spectrum machines support L3 stats by binding a counter to a RIF, a
hardware object representing a router interface. Recognize the netdevice
notifier events, NETDEV_OFFLOAD_XSTATS_*, to support enablement,
disablement, and reporting back to core.
As a netdevice gains a RIF, if L3 stats are enabled, install the counters,
and ping the core so that a userspace notification can be emitted.
Similarly, as a netdevice loses a RIF, push the as-yet-unreported
statistics to the core, so that they are not lost, and ping the core to
emit userspace notification.

The function mlxsw_reg_ritr_counter_pack() formats a register to configure
a router interface (RIF) counter. The parameter `egress' determines whether
an ingress or egress counter is to be configured. RITR, the register in
question, has two sets of counter-related fields: one for ingress, one for
egress. When setting values of the fields, the function sets the proper
counter index field, but when setting the counter type, it always sets the
egress field. Thus configuration of ingress counters is broken, and in fact
an attempt to configure an ingress counter mangles a previously configured
egress counter.
This was never discovered, because there is currently no way to enable
ingress counters on a router interface, only the egress one.
Fix in an obvious way.

Today when VFs are put in promiscuous mode, they can request PF
to configure device for them to receive all VLANs traffic regardless
of what vlan is configured by the PF (via ip link) and PF allows this
config request regardless of whether VF is trusted or not.
From security POV, when VLAN is configured for VF through PF (via ip link),
honour such config requests from VF only when they are configured to be
trusted, otherwise restrict such VFs vlan promisc mode config.

as well as support for the driver to specify a request as its primary
MAC address. He also refactors VLAN V2 capability exchange into more
generic extended capabilities to ease the addition of future
capabilities. Finally, he corrects the incorrect return of iavf_status
values and removes non-inclusive language.
Minghao Chi removes unneeded variables, instead returning values
directly.

Affinity hints were being set to CPUs in local NUMA node first, and then
in other CPUs. This was creating 2 unintended issues:
1. Channels created to be assigned each to a different physical core
were assigned to hyperthreading siblings because of being in same
NUMA node.
Since the patch previous to this one, this did not longer happen
with default rss_cpus modparam because less channels are created.
2. XDP channels could be assigned to CPUs in different NUMA nodes,
decreasing performance too much (to less than half in some of my
tests).
This patch sets the affinity hints spreading the channels only in local
NUMA node's CPUs. A fallback for the case that no CPU in local NUMA node
is online has been added too.
Example of CPUs being assigned in a non optimal way before this and the
previous patch (note: in this system, xdp-8 to xdp-15 are created
because num_possible_cpus == 64, but num_present_cpus == 32 so they're
never used):

Several functions in the iAVF core files take status values of the enum
iavf_status and convert them into integer values. This leads to
confusion as functions return both Linux errno values and status codes
intermixed. Reporting status codes as if they were "errno" values can
lead to confusion when reviewing error logs. Additionally, it can lead
to unexpected behavior if a return value is not interpreted properly.
Fix this by introducing iavf_status_to_errno, a switch that explicitly
converts from the status codes into an appropriate error value. Also
introduce a virtchnl_status_to_errno function for the one case where we
were returning both virtchnl status codes and iavf_status codes in the
same function.

In order to handle the capability exchange necessary for
VIRTCHNL_VF_OFFLOAD_VLAN_V2, the driver must send
a VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS message. This must occur prior to
__IAVF_CONFIG_ADAPTER, and the driver must wait for the response from
the PF.
To handle this, the __IAVF_INIT_GET_OFFLOAD_VLAN_V2_CAPS state was
introduced. This state is intended to process the response from the VLAN
V2 caps message. This works ok, but is difficult to extend to adding
more extended capability exchange.
Existing (and future) AVF features are relying more and more on these
sort of extended ops for processing additional capabilities. Just like
VLAN V2, this exchange must happen prior to __IAVF_CONFIG_ADPATER.
Since we only send one outstanding AQ message at a time during init, it
is not clear where to place this state. Adding more capability specific
states becomes a mess. Instead of having the "previous" state send
a message and then transition into a capability-specific state,
introduce __IAVF_EXTENDED_CAPS state. This state will use a list of
extended_caps that determines what messages to send and receive. As long
as there are extended_caps bits still set, the driver will remain in
this state performing one send or one receive per state machine loop.
Refactor the VLAN V2 negotiation to use this new state, and remove the
capability-specific state. This makes it significantly easier to add
a new similar capability exchange going forward.
Extended capabilities are processed by having an associated SEND and
RECV extended capability bit. During __IAVF_EXTENDED_CAPS, the
driver checks these bits in order by feature, first the send bit for
a feature, then the recv bit for a feature. Each send flag will call
a function that sends the necessary response, while each receive flag
will wait for the response from the PF. If a given feature can't be
negotiated with the PF, the associated flags will be cleared in
order to skip processing of that feature.

====================
mlx5-next 2022-22-02
The following PR includes updates to mlx5-next branch:
Headlines:
==========
1) Jakub cleans up unused static inline functions
2) I did some low level firmware command interface return status changes to
provide the caller with full visibility on the error/status returned by
the Firmware.
3) Use the new command interface in RDMA DEVX usecases to avoid flooding
dmesg with some "expected" user error prone use cases.
4) Moshe also uses the new command interface to grab the specific error
code from MFRL register command to provide the exact error reason for
why SW reset couldn't perform internally in FW.
5) From Mark Bloch: Lag, drop packets in hardware when possible
In active-backup mode the inactive interface's packets are dropped by the
bond device. In switchdev where TC rules are offloaded to the FDB
this can lead to packets being hit in the FDB where without offload
they would have been dropped before reaching TC rules in the kernel.
Create a drop rule to make sure packets on inactive ports are dropped
before reaching the FDB.
Listen on NETDEV_CHANGEUPPER / NETDEV_CHANGEINFODATA events and record
the inactive state and offload accordingly.

Changes introduced since the merge window in the spi subsystem and
available at:
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git tags/spi-remove-void
make the remove() callback for spi return void rather than int, breaking
the newly added dm9051 driver fail to build. This patch fixes this
issue, converting the remove() function provided by the driver to return
void.

Mark Brown says:
====================
spi: Make remove() return void
This series from Uwe Kleine-König converts the spi remove function to
return void since there is nothing useful that we can do with a failure
and it as more buses are converted it'll enable further work on the
driver core.

Similar to "igc_read_phy_reg_gpy: drop premature return" patch.
igc_write_phy_reg_gpy checks the return value from igc_write_phy_reg_mdic
and if it's not 0, returns immediately. By doing this, it leaves the HW
semaphore in the acquired state.
Drop this premature return statement, the function returns after
releasing the semaphore immediately anyway.

As more police parameters are passed to flow_offload, driver can check
them to make sure hardware handles packets in the way indicated by tc.
The conform-exceed control should be drop/pipe or drop/ok. Besides,
for drop/ok, the police should be the last action. As hardware can't
configure peakrate/avrate/overhead, offload should not be supported if
any of them is configured.

Currently ocelot uses a pvid of 0 for standalone ports and ports under a
VLAN-unaware bridge, and the pvid of the bridge for ports under a
VLAN-aware bridge. Standalone ports do not perform learning, but packets
received on them are still subject to FDB lookups. So if the MAC DA that
a standalone port receives has been also learned on a VLAN-unaware
bridge port, ocelot will attempt to forward to that port, even though it
can't, so it will drop packets.
So there is a desire to avoid that, and isolate the FDBs of different
bridges from one another, and from standalone ports.
The ocelot switch library has two distinct entry points: the felix DSA
driver and the ocelot switchdev driver.
We need to code up a minimal bridge_num allocation in the ocelot
switchdev driver too, this is copied from DSA with the exception that
ocelot does not care about DSA trees, cross-chip bridging etc. So it
only looks at its own ports that are already in the same bridge.
The ocelot switchdev driver uses the bridge_num it has allocated itself,
while the felix driver uses the bridge_num allocated by DSA. They are
both stored inside ocelot_port->bridge_num by the common function
ocelot_port_bridge_join() which receives the bridge_num passed by value.
Once we have a bridge_num, we can only use it to enforce isolation
between VLAN-unaware bridges. As far as I can see, ocelot does not have
anything like a FID that further makes VLAN 100 from a port be different
to VLAN 100 from another port with regard to FDB lookup. So we simply
deny multiple VLAN-aware bridges.
For VLAN-unaware bridges, we crop the 4000-4095 VLAN region and we
allocate a VLAN for each bridge_num. This will be used as the pvid of
each port that is under that VLAN-unaware bridge, for as long as that
bridge is VLAN-unaware.
VID 0 remains only for standalone ports. It is okay if all standalone
ports use the same VID 0, since they perform no address learning, the
FDB will contain no entry in VLAN 0, so the packets will always be
flooded to the only possible destination, the CPU port.
The CPU port module doesn't need to be member of the VLANs to receive
packets, but if we use the DSA tag_8021q protocol, those packets are
part of the data plane as far as ocelot is concerned, so there it needs
to. Just ensure that the DSA tag_8021q CPU port is a member of all
reserved VLANs when it is created, and is removed when it is deleted.

Fungible cards have a number of different PCI functions and thus
different drivers, all of which use a common method to initialize and
interact with the device. This commit adds a library module that
collects these common mechanisms. They mainly deal with device
initialization, setting up and destroying queues, and operating an admin
queue. A subset of the FW interface is also included here.
