The ice_read_phy_tstamp_ll_e810 function repeatedly reads the PF_SB_ATQBAL
register until the TS_LL_READ_TS bit is cleared. This is a perfect
candidate for using rd32_poll_timeout. However, the default implementation
uses a sleep-based wait. Use read_poll_timeout_atomic macro which is based
on the non-sleeping implementation and use it to replace the loop reading
in the ice_read_phy_tstamp_ll_e810 function.

Firmware generates events for global events or port specific events.
Driver shall subscribe for health status events from firmware on supported
FW versions >= 1.7.6.
Driver shall expose those under specific health reporter, two new
reporters are introduced:
- FW health reporter shall represent global events (problems with the
image, recovery mode);
- Port health reporter shall represent port-specific events (module
failure).
Firmware only reports problems when those are detected, it does not store
active fault list.
Driver will hold only last global and last port-specific event.
Driver will report all events via devlink health report,
so in case of multiple events of the same source they can be reviewed
using devlink autodump feature.

The new recipe should be added even if exactly the same recipe already
exists with different priority.
Example use case is when the rule is being added from TC tool context.
It should has the highest priority, but if the recipe already exists
the rule will inherit it priority. It can lead to the situation when
the rule added from TC tool has lower priority than expected.
The solution is to check the recipe priority when trying to find
existing one.
Previous recipe is still useful. Example:
RID 8 -> priority 4
RID 10 -> priority 7
The difference is only in priority rest is let's say eth + mac +
direction.
Adding ARP + MAC_A + RX on RID 8, forward to VF0_VSI
After that IP + MAC_B + RX on RID 10 (from TC tool), forward to PF0
Both will work.
In case of adding ARP + MAC_A + RX on RID 8, forward to VF0_VSI
ARP + MAC_A + RX on RID 10, forward to PF0.
Only second one will match, but this is expected.

Split ice_init_hw() call out from ice_init_dev(). Such move enables
pulling the former to be even earlier on call path, what would enable
moving ice_adapter init to be between the two (in subsequent commit).
Such move enables ice_adapter to know about number of PFs.
Do the same for ice_deinit_hw(), so the init and deinit calls could
be easily mirrored.
Next commit will rename unrelated goto labels to unroll prefix.

XPS can cause reorders because of the relaxed OOO
conditions for pure ACK packets.
For hosts not using RFS, what can happpen is that ACK
packets are sent on behalf of the cpu processing NIC
interrupts, selecting TX queue A for ACK packet P1.
Then a subsequent sendmsg() can run on another cpu.
TX queue selection uses the socket hash and can choose
another queue B for packets P2 (with payload).
If queue A is more congested than queue B,
the ACK packet P1 could be sent on the wire after
P2.
A linux receiver when processing P1 (after P2) currently increments
LINUX_MIB_PAWSESTABREJECTED (TcpExtPAWSEstab)
and use TCP_RFC7323_PAWS drop reason.
It might also send a DUPACK if not rate limited.
In order to better understand this pattern, this
patch adds a new drop_reason : TCP_RFC7323_PAWS_ACK.
For old ACKS like these, we no longer increment
LINUX_MIB_PAWSESTABREJECTED and no longer sends a DUPACK,
keeping credit for other more interesting DUPACK.

The ethtool_get_status callback currently handles all status and PSE
information within a single function. This approach has two key
drawbacks:
1. If the core requires some information for purposes other than
ethtool_get_status, redundant code will be needed to fetch the same
data from the driver (like is_enabled).
2. Drivers currently have access to all information passed to ethtool.
New variables will soon be added to ethtool status, such as PSE ID,
power domain IDs, and budget evaluation strategies, which are meant
to be managed solely by the core. Drivers should not have the ability
to modify these variables.
To resolve these issues, ethtool_get_status has been split into multiple
callbacks, with each handling a specific piece of information required
by ethtool or the core.

The regulator framework uses current limits, but the PSE standard and

current to power within each driver, perform the conversion in the PSE

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.

The following patchset contains a small batch of Netfilter/IPVS updates
for net-next:
1) Remove unused genmask parameter in nf_tables_addchain()
2) Speed up reads from /proc/net/ip_vs_conn, from Florian Westphal.
3) Skip empty buckets in hashlimit to avoid atomic operations that results
in false positive reports by syzbot with lockdep enabled, patch from
Eric Dumazet.
4) Add conntrack event timestamps available via ctnetlink,
from Florian Westphal.

====================
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.
changes v6:
- drop ethtool_stat_add patch
changes v5:
- rebase against latest net-next

Introduce a new way to report PHY statistics in a structured and
standardized format using the netlink API. This new method does not
replace the old driver-specific stats, which can still be accessed with
`ethtool -S <eth name>`. The structured stats are available with
`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.

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.

====================
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.
