In mt7531_cpu_port_config(), if the variable port is neither 5 nor 6,
then variable interface will be used uninitialised. Change the function
to return -EINVAL in this case.
As the return value of mt7531_cpu_port_config() is never checked
(even though it returns an int) add a check in the correct place so that
the error can be passed up the call stack. Now that we correctly handle
errors thrown in this function, also check the return value of
mt7531_mac_config() in case an error occurs here. Also add misisng
checks to mt7530_setup() and mt7531_setup(), which are another level

Currently the backlog status in not exposed to user-space.
Since long backlogs (or simply not empty ones) can be a
source of noticeable latency, -RT deployments need some way
to inspect it.
Additionally, there isn't a direct match between 'softnet_stat'
lines and the related CPU - sd for offline CPUs are not dumped -
so this patch also includes the CPU id into such entry.

The PCI vendor IDs in the documentation inaccurately describe the ENA
devices. For example, the 1d0f:ec20 can have LLQ support. The driver
loads in LLQ mode by default, and a message is printed to the kernel
ring if the mode isn't supported by the device, so the device table
isn't needed.
Also, LLQ can support various entry sizes, so the documentation is
updated to reflect that.
Interrupt moderation description is also updated to be more accurate.

The formal name changes to "ENA_ADMIN_RSS_INDIRECTION_TABLE_CONFIG".
Indirection is the ability to reference "something" using "something else"
instead of the value itself.
Indirection table, as the name implies, is the ability to reference
CPU/Queue value using hash-to-CPU table instead of CPU/Queue itself.
This patch renames the variable keys_num, which describes the number of
words in the RSS hash key, to key_parts which makes its purpose clearer
in RSS context.

====================
DSA with VLAN filtering and offloading masters
This series attempts to make DSA VLANs work in the presence of a master
interface that is:
- filtering, so it drops VLANs that aren't explicitly added to its
filter list
- offloading, so the old assumptions in the tagging code about there
being a VLAN tag in the skb are not necessarily true anymore.
For more context:
https://lore.kernel.org/netdev/20200910150738.mwhh2i6j2qgacqev@skbuf/
This probably marks the beginning of a series of patches in which DSA
starts paying much more attention to its upper interfaces, not only for
VLAN purposes but also for address filtering and for management of the
CPU flooding domain. There was a comment from Florian on whether we
could factor some of the mlxsw logic into some common functionality, but
it doesn't look so. This seems bound to be open-coded, but frankly there
isn't a lot to it.
Changes in v2:
Applied Florian's cosmetic suggestion in patch 4/9.

The whole purpose of tag_8021q is to send VLAN-tagged traffic to the
CPU, from which the driver can decode the source port and switch id.
Currently this only works if the VLAN filtering on the master is
disabled. Change that by explicitly adding code to tag_8021q.c to add
the VLANs corresponding to the tags to the filter of the master
interface.
Because we now need to call vlan_vid_add, then we also need to hold the
RTNL mutex. Propagate that requirement to the callers of dsa_8021q_setup
and modify the existing call sites as appropriate. Note that one call
path, sja1105_best_effort_vlan_filtering_set -> sja1105_vlan_filtering
-> sja1105_setup_8021q_tagging, was already holding this lock.

Most DSA switch tags shift the EtherType to the right, causing the
master to not parse the VLAN as VLAN.
However, not all switches do that (example: tail tags, tag_8021q etc),
and if the DSA master has "rx-vlan-filter: on" in ethtool -k, then we
have a problem.
Therefore, we could populate the VLAN table of the master, just in case
(for some switches it will not make a difference), so that network I/O
can work even with a VLAN filtering master.

When the bridge has VLAN awareness disabled there isn't any duplication
of functionality, since the bridge does not process VLAN. Don't deny
adding 8021q uppers to DSA switch ports in that case. The switch is
supposed to simply pass traffic leaving the VLAN tag as-is, and the
stack will happily strip the VLAN tag for all 8021q uppers that exist.
We need to ensure that there are no 8021q uppers when the user attempts
to enable bridge vlan_filtering.

The current logic beats me a little bit. The comment that "bridge skips
-EOPNOTSUPP, so skip the prepare phase" was introduced in commit
fb2dabad69f0 ("net: dsa: support VLAN filtering switchdev attr").
I'm not sure:
(a) ok, the bridge skips -EOPNOTSUPP, but, so what, where are we
returning -EOPNOTSUPP?
(b) even if we are, and I'm just not seeing it, what is the causality
relationship between the bridge skipping -EOPNOTSUPP and DSA
skipping the prepare phase, and just returning zero?
One thing is certain beyond doubt though, and that is that DSA currently
refuses VLAN filtering from the "commit" phase instead of "prepare", and
that this is not a good thing:

that is way harder) into the prepare stage of the switchdev transaction.

PRECHANGEUPPER
This is checking for the following order of operations, and makes sure
to deny that configuration:
ip link add link swp2 name swp2.100 type vlan id 100
ip link add br0 type bridge vlan_filtering 1
ip link set swp2 master br0
bridge vlan add dev swp2 vid 100
Instead of using vlan_for_each(), which looks at the VLAN filters
installed with vlan_vid_add(), just track the 8021q uppers. This has the
advantage of freeing up the vlan_vid_add() call for actual VLAN
filtering.
There is another change in this patch. The check is moved in slave.c,
from switch.c. I don't think it makes sense to have this 8021q upper
check for each switch port that gets notified of that VLAN addition
(these include DSA links and CPU ports, we know those can't have 8021q
uppers because they don't have a net_device registered for them), so
just do it in slave.c, for that one slave interface.

DSA tries to prevent having a VLAN added by a bridge and by an 802.1Q
upper at the same time. It does that by checking the VID in
.ndo_vlan_rx_add_vid(), since that's something that the 8021q module
calls, via vlan_vid_add(). When a VLAN matches in both subsystems, this
check returns -EBUSY.
However the vlan_vid_add() function isn't specific to the 8021q module
in any way at all. It is simply the kernel's way to tell an interface to
add a VLAN to its RX filter and not drop that VLAN. So there's no reason
to return -EBUSY when somebody tries to call vlan_vid_add() for a VLAN
that was installed by the bridge. The proper behavior is to accept that
configuration.
So what's wrong is how DSA checks that it has an 8021q upper. It should
look at the actual uppers for that, not just assume that the 8021q
module was somewhere in the call stack of .ndo_vlan_rx_add_vid().

We'll be adding a new check in the PRECHANGEUPPER notifier, where we'll
need to check some VLAN uppers. It is hard to do that when there is
already a function named dsa_slave_upper_vlan_check. So rename this one.
Not to mention that this function probably shouldn't have started with
"dsa_slave_" in the first place, since the struct net_device argument
isn't a DSA slave, but an 8021q upper of one.

There doesn't seem to be any strong technical reason for doing it this

Andrew Lunn says:
====================
mv88e6xxx: Add devlink regions support
Make use of devlink regions to allow read access to some of the
internal of the switches. Currently access to global1, global2 and the
ATU is provided.
The switch itself will never trigger a region snapshot, it is assumed
it is performed from user space as needed.
v2:
Remove left of debug print
Comment ATU format is generic to mv88e6xxx
Combine declaration and the assignment on a single line.
v3:
Drop support for port regions
Improve the devlink API with a priv member and passing the region to
the snapshot function
Make the helper to convert from devlink to ds an inline function
v4:
Add missing kerneldoc in ICE driver
Fix typo for global2 reading global1 registers
Make use of enum to make code more readable
====================
