DIV_ROUND_CLOSEST() after kstrtoul() results in an overflow if a large
number such as 18446744073709551615 is provided by the user.
Fix it by reordering clamp_val() and DIV_ROUND_CLOSEST() operations.

Due to a limitation in available memory, the MT7916 firmware can only
handle either 5 GHz or 6 GHz at a time. It does not support runtime
switching without a full restart.
On older firmware, this accidentally worked to some degree due to missing
checks, but couldn't be supported properly, because it left the 6 GHz
channels uncalibrated.
Newer firmware refuses to start on either band if the passed EEPROM
data indicates support for both.
Deal with this limitation by using a module parameter to specify the
preferred band in case both are supported.

When initializing the network card, unplugging the device will
trigger an -EPROTO error, resulting in a flood of error messages
being printed frantically.
The exception is printed as follows：
mt76x2u 2-2.4:1.0: vendor request req:47 off:9018 failed:-71
mt76x2u 2-2.4:1.0: vendor request req:47 off:9018 failed:-71
...
It will continue to print more than 2000 times for about 5 minutes,
causing the usb device to be unable to be disconnected. During this
period, the usb port cannot recognize the new device because the old
device has not disconnected.
There may be other operating methods that cause -EPROTO, but -EPROTO is
a low-level hardware error. It is unwise to repeat vendor requests
expecting to read correct data. It is a better choice to treat -EPROTO
and -ENODEV the same way.
Similar to commit 9b0f100c1970 ("mt76: usb: process URBs with status
EPROTO properly") do no schedule rx_worker for urb marked with status
set -EPROTO. I also reproduced this situation when plugging and
unplugging the device, and this patch is effective.
Just do not vendor request again for urb marked with status set -EPROTO.

vsock: some fixes due to transport de-assignment
v1: https://lore.kernel.org/netdev/20250108180617.154053-1-sgarzare@redhat.com/
v2:
- Added patch 3 to cancel the virtio close delayed work when de-assigning
the transport
- Added patch 4 to clean the socket state after de-assigning the transport
- Added patch 5 as suggested by Michael and Hyunwoo Kim. It's based on
Hyunwoo Kim and Wongi Lee patch [1] but using WARN_ON and covering more
functions
- Added R-b/T-b tags
This series includes two patches discussed in the thread started by
Hyunwoo Kim a few weeks ago [1], plus 3 more patches added after some
discussions on v1 (see changelog). All related to the case where a vsock
socket is de-assigned from a transport (e.g., because the connect fails
or is interrupted by a signal) and then assigned to another transport
or to no-one (NULL).
I tested with usual vsock test suite, plus Michal repro [2]. (Note: the repo
works only if a G2H transport is not loaded, e.g. virtio-vsock driver).
The first patch is a fix more appropriate to the problem reported in
that thread, the second patch on the other hand is a related fix but
of a different problem highlighted by Michal Luczaj. It's present only
in vsock_bpf and already handled in af_vsock.c
The third patch is to cancel the virtio close delayed work when de-assigning
the transport, the fourth patch is to clean the socket state after de-assigning
the transport, the last patch adds warnings and prevents null-ptr-deref in
vsock_*[has_data|has_space].
Hyunwoo Kim, Michal, if you can test and report your Tested-by that
would be great!

Recent reports have shown how we sometimes call vsock_*_has_data()
when a vsock socket has been de-assigned from a transport (see attached
links), but we shouldn't.
Previous commits should have solved the real problems, but we may have
more in the future, so to avoid null-ptr-deref, we can return 0
(no space, no data available) but with a warning.
This way the code should continue to run in a nearly consistent state
and have a warning that allows us to debug future problems.

Transport's release() and destruct() are called when de-assigning the
vsock transport. These callbacks can touch some socket state like
sock flags, sk_state, and peer_shutdown.
Since we are reassigning the socket to a new transport during
vsock_connect(), let's reset these fields to have a clean state with
the new transport.

During virtio_transport_release() we can schedule a delayed work to
perform the closing of the socket before destruction.
The destructor is called either when the socket is really destroyed
(reference counter to zero), or it can also be called when we are
de-assigning the transport.
In the former case, we are sure the delayed work has completed, because
it holds a reference until it completes, so the destructor will
definitely be called after the delayed work is finished.
But in the latter case, the destructor is called by AF_VSOCK core, just
after the release(), so there may still be delayed work scheduled.
Refactor the code, moving the code to delete the close work already in
the do_close() to a new function. Invoke it during destruction to make
sure we don't leave any pending work.

If the socket has been de-assigned or assigned to another transport,
we must discard any packets received because they are not expected
and would cause issues when we access vsk->transport.
A possible scenario is described by Hyunwoo Kim in the attached link,
where after a first connect() interrupted by a signal, and a second
connect() failed, we can find `vsk->transport` at NULL, leading to a
NULL pointer dereference.

Add multicast filtering support for VLAN interfaces in HSR offload mode
for ICSSG driver.
The driver calls vlan_for_each() API on the hsr device's ndev to get the
list of available vlans for the hsr device. The driver then sync mc addr of
vlan interface with a locally mainatined list emac->vlan_mcast_list[vid]
using __hw_addr_sync_multiple() API.
The driver then calls the sync / unsync callbacks.
In the sync / unsync call back, driver checks if the vdev's real dev is
hsr device or not. If the real dev is hsr device, driver gets the per
port device using hsr_get_port_ndev() and then driver passes appropriate
vid to FDB helper functions.

Create an API to get the net_device to the slave port of HSR device. The
API will take hsr net_device and enum hsr_port_type for which we want the
net_device as arguments.
This API can be used by client drivers who support HSR and want to get
the net_devcie of slave ports from the hsr device. Export this API for
the same.
This API needs the enum hsr_port_type to be accessible by the drivers using
hsr. Move the enum hsr_port_type from net/hsr/hsr_main.h to
include/linux/if_hsr.h for the same.

Add multicast filtering support for VLAN interfaces in dual EMAC mode
for ICSSG driver.
The driver uses vlan_for_each() API to get the list of available
vlans. The driver then sync mc addr of vlan interface with a locally
mainatined list emac->vlan_mcast_list[vid] using __hw_addr_sync_multiple()
API.
__hw_addr_sync_multiple() is used instead of __hw_addr_sync() to sync
vdev->mc with local list because the sync_cnt for addresses in vdev->mc
will already be set by the vlan_dev_set_rx_mode() [net/8021q/vlan_dev.c]
and __hw_addr_sync() only syncs when the sync_cnt == 0. Whereas
__hw_addr_sync_multiple() can sync addresses even if sync_cnt is not 0.
Export __hw_addr_sync_multiple() so that driver can use it.
Once the local list is synced, driver calls __hw_addr_sync_dev() with
the local list, vdev, sync and unsync callbacks.
__hw_addr_sync_dev() is used with the local maintained list as the list
to synchronize instead of using __dev_mc_sync() on vdev because
__dev_mc_sync() on vdev will call __hw_addr_sync_dev() on vdev->mc and
sync_cnt for addresses in vdev->mc will already be set by the
vlan_dev_set_rx_mode() [net/8021q/vlan_dev.c] and __hw_addr_sync_dev()
only syncs if the sync_cnt of addresses in the list (vdev->mc in this case)
is 0. Whereas __hw_addr_sync_dev() on local list will work fine as the
sync_cnt for addresses in the local list will still be 0.
Based on change in addresses in the local list, sync / unsync callbacks
are invoked. In the sync / unsync API in driver, based on whether the ndev
is vlan or not, driver passes appropriate vid to FDB helper functions.

Introduce unified and structured PHY
This patch set introduces a unified and well-structured interface for
reporting PHY statistics. Instead of relying on arbitrary strings in PHY
drivers, this interface provides a consistent and structured way to
expose PHY statistics to userspace via ethtool.
The initial groundwork for this effort was laid by Jakub Kicinski, who
contributed patches to plumb PHY statistics to drivers and added support
for structured statistics in ethtool. Building on Jakub's work, I tested
the implementation with several PHYs, addressed a few issues, and added
support for statistics in two specific PHY drivers.
Most of changes are tracked in separate patches.

- drop ethtool_stat_add patch

`ethtool -S <eth name> --all-groups`.
This new method makes it easier to diagnose problems by organizing stats
in a consistent and documented way.

Introduce support for standardized PHY statistics reporting in ethtool
by extending the PHYLIB framework. Add the functions
phy_ethtool_get_phy_stats() and phy_ethtool_get_link_ext_stats() to
provide a consistent interface for retrieving PHY-level and
link-specific statistics. These functions are used within the ethtool
implementation to avoid direct access to the phy_device structure
outside of the PHYLIB framework.
A new structure, ethtool_phy_stats, is introduced to standardize PHY
statistics such as packet counts, byte counts, and error counters.
Drivers are updated to include callbacks for retrieving PHY and
link-specific statistics, ensuring values are explicitly set only for
supported fields, initialized with ETHTOOL_STAT_NOT_SET to avoid
ambiguity.

Adapt linkstate_get_sqi() and linkstate_get_sqi_max() to take a
phy_device argument directly, enabling support for setups with
multiple PHYs. The previous assumption of a single PHY attached to
a net_device no longer holds.
Use ethnl_req_get_phydev() to identify the appropriate PHY device
for the operation. Update linkstate_prepare_data() and related
logic to accommodate this change, ensuring compatibility with
multi-PHY configurations.

pfcp_newlink() links the device to a list in dev_net(dev) instead
of net, where a udp tunnel socket is created.
Even when net is removed, the device stays alive on dev_net(dev).
Then, removing net triggers the splat below. [0]
In this example, pfcp0 is created in ns2, but the udp socket is
created in ns1.
ip netns add ns1
ip netns add ns2
ip -n ns1 link add netns ns2 name pfcp0 type pfcp
ip netns del ns1
Let's link the device to the socket's netns instead.
Now, pfcp_net_exit() needs another netdev iteration to remove
all pfcp devices in the netns.
pfcp_dev_list is not used under RCU, so the list API is converted
to the non-RCU variant.
pfcp_net_exit() can be converted to .exit_batch_rtnl() in net-next.

However, even after the gtp device is moved to another netns,

Let's use for_each_netdev_rcu() for netdev traversal in

As discussed in [0], rehash4 could be missed in udp_lib_rehash() when
udp hash4 changes while hash2 doesn't change. This patch fixes this by
moving rehash4 codes out of rehash2 checking, and then rehash2 and
rehash4 are done separately.
By doing this, we no longer need to call rehash4 explicitly in
udp_lib_hash4(), as the rehash callback in __ip4_datagram_connect takes
it. Thus, now udp_lib_hash4() returns directly if the sk is already
hashed.
Note that uhash4 may fail to work under consecutive connect(<dst
address>) calls because rehash() is not called with every connect(). To
overcome this, connect(<AF_UNSPEC>) needs to be called after the next
connect to a new destination.

dev_deactivate_many() role is to remove the qdiscs
of a network device.
When/if a qdisc is dismantled, an rcu grace period
is needed to make sure all outstanding qdisc enqueue
are done before we proceed with a qdisc reset.
Most virtual devices do not have a qdisc.
We can call the expensive synchronize_net() only
if needed.
Note that dev_deactivate_many() does not have to deal
with qdisc-less dev_queue_xmit, as an old comment
was claiming.

Tariq Toukan says:
====================
mlx5 HW-Managed Flow Steering in FS core level
This patchset by Moshe follows Yevgeny's patchsets [1][2] on subject
"HW-Managed Flow Steering in mlx5 driver". As introduced there in HW
managed Flow Steering mode (HWS) the driver is configuring steering
rules directly to the HW using WQs with a special new type of WQE (Work
Queue Element). This way we can reach higher rule insertion/deletion
rate with much lower CPU utilization compared to SW Managed Flow
Steering (SWS).
This patchset adds API to manage namespace, flow tables, flow groups and
prepare FTE (Flow Table Entry) rules. It also adds caching and pool
mechanisms for HWS actions to allow sharing of steering actions among
different rules. The implementation of this API in FS layer, allows FS
core to use HW Managed Flow Steering in addition to the existing FW or
SW Managed Flow Steering.
Patch 13 of this series adds support for configuring HW Managed Flow
Steering mode through devlink param, similar to configuring SW Managed
Flow Steering mode:
# devlink dev param set pci/0000:08:00.0 name flow_steering_mode \
cmode runtime value hmfs
In addition, the series contains 2 HWS patches from Yevgeny that
implement flow update support.

This patch is the second part of update flow implementation.
Instead of using two action RTCs, we use the same RTC which is twice
the size of what was required before the update flow support.
This way we always allocate STEs from the same RTC (same pool),
which means that update is done similar to how create is done.
The bigger size allows us to allocate and write new STEs, and
later free the old (pre-update) STEs.
Similar to rule creation, STEs are written in reverse order:
- write action STEs, while match STE is still pointing to
the old action STEs
- overwrite the match STE with the new one, which now
is pointing to the new action STEs
Old action STEs can be freed only once we got completion on the
writing of the new match STE. To implement this we added new rule
states: UPDATING/UPDATED. Rule is moved to UPDATING state in the
beginning of the update flow. Once all completions are received,
rule is moved to UPDATED state. At this point old action STEs are
freed and rule goes back to CREATED state.

This patch is the first part of update flow implementation.
Update flow should support rules with single STE (match STE only),
as well as rules with multiple STEs (match STE plus action STEs).
Supporting the rules with single STE is straightforward: we just
overwrite the STE, which is an atomic operation.
Supporting the rules with action STEs is a more complicated case.
The existing implementation uses two action RTCs per matcher and
alternates between the two for each update request.
This implementation was unnecessarily complex and lead to some
unhandled edge cases, so the support for rule update with multiple
STEs wasn't really functional.
This patch removes this code, and the next patch adds implementation
of a different approach.
Note that after applying this patch and before applying the next
patch we still have support for update rule with single STE (only
match STE w/o action STEs), but update will fail for rules with
action STEs.

Add support for HW Steering action of vport destination. Add dest vport
actions cache. Hold action in cache per vport / vport and vhca_id. Add
action to cache on demand and remove on namespace closure to reduce
actions creation and destroy.

Add cache of destination flow table HWS action per HWS table. For each
flow table created cache a destination action towards this table. The
cached action will be used on the downstream patch whenever a rule
requires such action.

Multiple flow counters can utilize a single Hardware Steering (HWS)
action for Hardware Steering rules. Given that these counter bulks are
not exclusively created for Hardware Steering, but also serve purposes
such as statistics gathering and other steering modes, it's more
efficient to create the HWS action only when it's first needed by a
Hardware Steering rule. This approach allows for better resource
management through the use of a reference count, rather than
automatically creating an HWS action for every bulk of flow counters.
