Fix the tag_ksz egress mask for DSA_TAG_PROTO_KSZ8795, the port is
encoded in the two and not three LSB. This fix is for completeness,
for example the bug doesn't manifest itself on the KSZ8794 because bit

The KSZ87xx switches have 32 static MAC address table entries and not
8. This fixes -ENOSPC non-critical errors from ksz8_add_sta_mac when
configured as a bridge.
Add a new ksz87xx_dev_ops structure to be able to use the
ksz_r_mib_stat64 pointer for this family; this corrects a wrong
mib->counters cast to ksz88xx_stats_raw. This fixes iproute2
statistics. Rename ksz8_dev_ops structure to ksz88x3_dev_ops, in line
with ksz_is_* naming conventions from ksz_common.h.

virtio-net: synchronize op/admin state
This series tries to synchronize the operstate with the admin state
which allows the lower virtio-net to propagate the link status to the
upper devices like macvlan.
This is done by toggling carrier during ndo_open/stop while doing
other necessary serialization about the carrier settings during probe.
While at it, also fix a race between probe and ndo_set_features as we
didn't initalize the guest offload setting under rtnl lock.

Sometime, it would be useful to disable the configure change
notification from the driver. So this patch allows this by introducing
a variable config_change_driver_disabled and only allow the configure
change notification callback to be triggered when it is allowed by
both the virtio core and the driver. It is set to false by default to
hold the current semantic so we don't need to change any drivers.
The first user for this would be virtio-net.

Similar to commit 70f06c115b ("sched: act_ct: switch to per-action
label counting"), we should also switch to per-action label counting
in openvswitch conntrack, as Florian suggested.
The difference is that nf_connlabels_get() is called unconditionally
when creating an ct action in ovs_ct_copy_action(). As with these
flows:
table=0,ip,actions=ct(commit,table=1)
table=1,ip,actions=ct(commit,exec(set_field:0xac->ct_label),table=2)
it needs to make sure the label ext is created in the 1st flow before
the ct is committed in ovs_ct_commit(). Otherwise, the warning in
nf_ct_ext_add() when creating the label ext in the 2nd flow will
be triggered:
WARN_ON(nf_ct_is_confirmed(ct));

Commit 2acda57736 ("net/mlx5e: Improve remote NUMA preferences used for the IRQ affinity hints")
removed the usage of cpumask_local_spread().
The issue explained in this commit was fixed by
commit 406d394abf ("cpumask: improve on cpumask_local_spread() locality").
Since this commit, mlx5_cpumask_default_spread() is having the same
behavior as cpumask_local_spread().
This commit is about :
- removing the specific logic and use cpumask_local_spread() instead
- passing mlx5_core_dev as argument to more flexibility
mlx5_cpumask_default_spread() is kept as it could be useful for some
future specific quirks.

When a new IPv4 address is assigned via ioctl(SIOCSIFADDR),
inet_set_ifa() sets ifa->ifa_dev if it's different from in_dev
passed as an argument.
In this case, ifa is always a newly allocated object, and
ifa->ifa_dev is NULL.
inet_set_ifa() can be called for an existing reused ifa, then,
this check is always false.
Let's set ifa_dev in inet_alloc_ifa() and remove the check
in inet_set_ifa().
Now, inet_alloc_ifa() is symmetric with inet_rcu_free_ifa().

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) Ignores ifindex for types other than mcast/linklocal in ipv6 frag
reasm, from Tom Hughes.
2) Initialize extack for begin/end netlink message marker in batch,
from Donald Hunter.
3) Initialize extack for flowtable offload support, also from Donald.
4) Dropped packets with cloned unconfirmed conntracks in nfqueue,
later it should be possible to explore lookup after reinject but
Florian prefers this approach at this stage. From Florian Westphal.
5) Add selftest for cloned unconfirmed conntracks in nfqueue for
previous update.
6) Audit after filling netlink header successfully in object dump,
from Phil Sutter.
7-8) Fix concurrent dump and reset which could result in underflow
counter / quota objects.

pci_request_regions is called to apply for PCI I/O and memory resources
when the driver is initialized, Therefore, when the driver is uninstalled,
pci_release_regions should be used to release PCI I/O and memory resources
instead of pci_release_mem_regions is used to release memory reasouces
only.

When config TC during the reset process, may cause a deadlock, the flow is
as below:
pf reset start
│
▼
......
setup tc │
│ ▼
▼ DOWN: napi_disable()
napi_disable()(skip) │
│ │
▼ ▼
...... ......
│ │
▼ │
napi_enable() │
▼
UINIT: netif_napi_del()
│
▼
......
│
▼
INIT: netif_napi_add()
│
▼
...... global reset start
│ │
▼ ▼
UP: napi_enable()(skip) ......
│ │
▼ ▼
...... napi_disable()
In reset process, the driver will DOWN the port and then UINIT, in this
case, the setup tc process will UP the port before UINIT, so cause the
problem. Adds a DOWN process in UINIT to fix it.

Consider the followed case that the user change speed and reset the net
interface. Before the hw change speed successfully, the driver get old
old speed from hw by timer task. After reset, the previous speed is config
to hw. As a result, the new speed is configed successfully but lost after
PF reset. The followed pictured shows more dirrectly.

Currently, if hns3 PF or VF FLR reset failed after five times retry,
the reset done process will directly release the semaphore
which has already released in hclge_reset_prepare_general.
This will cause down operation fail.
So this patch fixes it by adding reset state judgement. The up operation is
only called after successful PF FLR reset.

When deleting netns, it is possible to still have some tasks running,
e.g. background tasks like tcpdump running in the background, not
stopped because the test has been interrupted.
Before deleting the netns, it is then safer to kill all attached PIDs,
if any. That should reduce some noises after the end of some tests, and
help with the debugging of some issues. That's why this modification is
seen as a "fix".

Fix an issue where `devm_regulator_register()` would fail for PSE
controllers that do not support current limit control, such as simple
GPIO-based controllers like the podl-pse-regulator. The
`REGULATOR_CHANGE_CURRENT` flag and `max_uA` constraint are now
conditionally set only if the `pi_set_current_limit` operation is
supported. This change prevents the regulator registration routine from
attempting to call `pse_pi_set_current_limit()`, which would return
`-EOPNOTSUPP` and cause the registration to fail.

Commit 94833addfa ("net: thunderx: Unembed netdev structure") had
a go at dynamically allocating the netdev structures for the thunderx_bgx
driver. This change results in my ThunderX box catching fire (to be fair,
it is what it does best).
The issues with this change are that:
- bgx_lmac_enable() is called *after* bgx_acpi_register_phy() and
bgx_init_of_phy(), both expecting netdev to be a valid pointer.
- bgx_init_of_phy() populates the MAC addresses for *all* LMACs
attached to a given BGX instance, and thus needs netdev for each of
them to have been allocated.
There is a few things to be said about how the driver mixes LMAC and
BGX states which leads to this sorry state, but that's beside the point.
To address this, go back to a situation where all netdev structures
are allocated before the driver starts relying on them, and move the
freeing of these structures to driver removal. Someone brave enough
can always go and restructure the driver if they want.

CMIS 5.2 standard section 9.4.2 defines four types of firmware update
supported mechanism: None, only LPL, only EPL, both LPL and EPL.
Currently, only LPL (Local Payload) type of write firmware block is
supported. However, if the module supports both LPL and EPL the flashing
process wrongly fails for no supporting LPL.
Fix that, by allowing the write mechanism to be LPL or both LPL and
EPL.

After a vsock socket has been added to a BPF sockmap, its prot->recvmsg
has been replaced with vsock_bpf_recvmsg(). Thus the following
recursiion could happen:
vsock_bpf_recvmsg()
-> __vsock_recvmsg()
-> vsock_connectible_recvmsg()
-> prot->recvmsg()
-> vsock_bpf_recvmsg() again
We need to fix it by calling the original ->recvmsg() without any BPF
sockmap logic in __vsock_recvmsg().
