There is an interdependence between the current link_an_mode and
pcs_neg_mode that some drivers rely upon to know whether inband or PHY
mode will be used.
In order to support detection of PCS and PHY inband capabilities
resulting in automatic selection of inband or PHY mode, we need to
cater for this, and support changing the MAC link_an_mode. However, we
end up with an inter-dependency between the current link_an_mode and
pcs_neg_mode.
To solve this, split the current link_an_mode into the requested
link_an_mode and active link_an_mode. The requested link_an_mode will
always be passed to phylink_pcs_neg_mode(), and the active link_an_mode
will be used for everything else, and only updated during
phylink_major_config(). This will ensure that phylink_pcs_neg_mode()'s
link_an_mode will not depend on the active link_an_mode that will,
in a future patch, depend on pcs_neg_mode.

Move the call to phylink_pcs_neg_mode() in phylink_major_config() after
we have selected the appropriate PCS to allow the PCS to be passed in.
Add struct phylink and struct phylink_pcs pointers to
phylink_pcs_neg_mode() and pass in the appropriate structures. Set
pl->pcs_neg_mode before returning, and remove the return value.
This will allow the capabilities of the PCS and any PHY to be used when
deciding which pcs_neg_mode should be used.

The driver is currently using an ACL key block that is not supported by
Spectrum-4. This works because the driver is only using a single field
from this key block which is located in the same offset in the
equivalent Spectrum-4 key block.
The issue was discovered when the firmware started rejecting the use of
the unsupported key block. The change has been reverted to avoid
breaking users that only update their firmware.
Nonetheless, fix the issue by using the correct key block.

Enhance observability of netconsole. Packet sends can fail.
Start tracking at least two failure possibilities: ENOMEM and
NET_XMIT_DROP for every target. Stats are exposed via an additional
attribute in CONFIGFS.
The exposed statistics allows easier debugging of cases when netconsole
messages were not seen by receivers, eliminating the guesswork if the
sender thinks that messages in question were sent out.
Stats are not reset on enable/disable/change remote ip/etc, they
belong to the netcons target itself.

Currently, TX power is reported on interface/wdev level as
part of NL80211_CMD_GET_INTERFACE. With MLO, Multiple links
can be part of an interface/wdev and hence its necessary to
report the TX power of each link.
Add support to send tx power for all valid links of an MLD as
part of NL80211_CMD_GET_INTERFACE request.
As far as userspace is concerned, there is no behavioral change
for Non-ML Interfaces. For ML interfaces, userspace should fetch
TX power that is nested inside NL80211_ATTR_MLO_LINKS, similar to
how channel info(NL80211_ATTR_WIPHY_FREQ) is fetched.

The ixgbe PF driver logs an info message when a VF attempts to negotiate an
API version which it does not support:
VF 0 requested invalid api version 6
The ixgbevf driver attempts to load with mailbox API v1.5, which is
required for best compatibility with other hosts such as the ESX VMWare PF.
The Linux PF only supports API v1.4, and does not currently have support
for the v1.5 API.
The logged message can confuse users, as the v1.5 API is valid, but just
happens to not currently be supported by the Linux PF.
Downgrade the info message to a debug message, and fix the language to
use 'unsupported' instead of 'invalid' to improve message clarity.
Long term, we should investigate whether the improvements in the v1.5 API
make sense for the Linux PF, and if so implement them properly. This may
require yet another API version to resolve issues with negotiating IPSEC
offload support.

Commit 339f28964147 ("ixgbevf: Add support for new mailbox communication
between PF and VF") added support for v1.5 of the PF to VF mailbox
communication API. This commit mistakenly enabled IPSEC offload for API
v1.5.
No implementation of the v1.5 API has support for IPSEC offload. This
offload is only supported by the Linux PF as mailbox API v1.4. In fact, the
v1.5 API is not implemented in any Linux PF.
Attempting to enable IPSEC offload on a PF which supports v1.5 API will not
work. Only the Linux upstream ixgbe and ixgbevf support IPSEC offload, and
only as part of the v1.4 API.
Fix the ixgbevf Linux driver to stop attempting IPSEC offload when
the mailbox API does not support it.
The existing API design choice makes it difficult to support future API
versions, as other non-Linux hosts do not implement IPSEC offload. If we
add support for v1.5 to the Linux PF, then we lose support for IPSEC
offload.
A full solution likely requires a new mailbox API with a proper negotiation
to check that IPSEC is actually supported by the host.

Commit d9028db618a6 ("idpf: convert to libeth Tx buffer completion")
inadvertently removed code that was necessary for the tx buffer cleaning
routine to iterate over all buffers associated with a packet.
When a frag is too large for a single data descriptor, it will be split
across multiple data descriptors. This means the frag will span multiple
buffers in the buffer ring in order to keep the descriptor and buffer
ring indexes aligned. The buffer entries in the ring are technically
empty and no cleaning actions need to be performed. These empty buffers
can precede other frags associated with the same packet. I.e. a single
packet on the buffer ring can look like:
buf[0]=skb0.frag0
buf[1]=skb0.frag1
buf[2]=empty
buf[3]=skb0.frag2
The cleaning routine iterates through these buffers based on a matching
completion tag. If the completion tag is not set for buf2, the loop will
end prematurely. Frag2 will be left uncleaned and next_to_clean will be
left pointing to the end of packet, which will break the cleaning logic
for subsequent cleans. This consequently leads to tx timeouts.
Assign the empty bufs the same completion tag for the packet to ensure
the cleaning routine iterates over all of the buffers associated with
the packet.

In switchdev mode the uplink VSI should receive all unmatched packets,
including VLANs. Therefore, VLAN pruning should be disabled if uplink is
in switchdev mode. It is already being done in ice_eswitch_setup_env(),
however the addition of ice_up() in commit 44ba608db509 ("ice: do
switchdev slow-path Rx using PF VSI") caused VLAN pruning to be
re-enabled after disabling it.
Add a check to ice_set_vlan_filtering_features() to ensure VLAN
filtering will not be enabled if uplink is in switchdev mode. Note that
ice_is_eswitch_mode_switchdev() is being used instead of
ice_is_switchdev_running(), as the latter would only return true after
the whole switchdev setup completes.

Currently rtnl_link_get_net_ifla() gets called twice when we create
peer devices, once in rtnl_add_peer_net() and once in each ->newlink()
implementation.
This looks safer, however, it leads to a classic Time-of-Check to
Time-of-Use (TOCTOU) bug since IFLA_NET_NS_PID is very dynamic. And
because of the lack of checking error pointer of the second call, it
also leads to a kernel crash as reported by syzbot.
Fix this by getting rid of the second call, which already becomes
redudant after Kuniyuki's work. We have to propagate the result of the
first rtnl_link_get_net_ifla() down to each ->newlink().

If we got an unprotected action frame with CSA and then we heard the
beacon with the CSA IE, we'll block the queues with the CSA reason
twice. Since this reason is refcounted, we won't wake up the queues
since we wake them up only once and the ref count will never reach 0.
This led to blocked queues that prevented any activity (even
disconnection wouldn't reset the queue state and the only way to recover
would be to reload the kernel module.
Fix this by not refcounting the CSA reason.

LAN7800/7850
Fix outdated MII_LPA data in the LAN88xx PHY, which is used in LAN7800

PHY cannot reliably update link status after parallel detection when the
link partner does not support auto-negotiation. To mitigate this, add a
PHY reset in `lan88xx_link_change_notify()` when `phydev->state` is
`PHY_NOLINK`, ensuring the PHY starts in a clean state and reports

Commit 2f4f9fe5bf5f ("bnxt_en: Support adding ntuple rules on RSS
contexts") added support for redirecting to an RSS context as an ntuple
rule action. However, it forgot to update the ETHTOOL_GRXCLSRULE
codepath. This caused `ethtool -n` to always report the action as
"Action: Direct to queue 0" which is wrong.
Fix by teaching bnxt driver to report the RSS context when applicable.

When hardware device group abstraction is introduced, the QMI firmware ready
event of different devices in a group can be received simultaneously. To
indicate the firmware ready event is completed for a particular device in a
group set a flag (ATH12K_FLAG_QMI_FW_READY_COMPLETE). This helps the upcoming
hardware recovery implementation for hardware device group abstraction.

In the upcoming hardware device group abstraction radios across different
devices can be grouped together to support multi-link operation and register as
a device group to mac80211.
Currently, ath12k_mac_allocate() and ath12k_mac_register() are part of
ath12k_core_start() and ath12k_core_pdev_create() respectively and are based on
per device (struct ath12k_base). These APIs can be decoupled and moved out to
ath12k_core_qmi_firmware_ready() itself. This refactor is helpful for device
group abstraction when mac80211 allocate and register will be changed from per
device (struct ath12k_base) to per device group (struct ath12k_hw_group).

Both ENETC PF and VF drivers share enetc_setup_tc_mqprio() to configure
MQPRIO. And enetc_setup_tc_mqprio() calls enetc_change_preemptible_tcs()
to configure preemptible TCs. However, only PF is able to configure
preemptible TCs. Because only PF has related registers, while VF does not
have these registers. So for VF, its hw->port pointer is NULL. Therefore,
VF will access an invalid pointer when accessing a non-existent register,
which will cause a crash issue. The simplified log is as follows.

Configuring TSN (Qbv, Qbu, PSFP) capabilities requires access to port
registers, which are available to the PSI but not the VSI.
Yet, the SI port capability register 0 (PSICAPR0), exposed to both PSIs
and VSIs, presents the same capabilities to the VF as to the PF, thus
leading the VF driver into thinking it can configure these features.
In the case of ENETC_SI_F_QBU, having it set in the VF leads to a crash:

while the other TSN features in the VF are harmless, because the
net_device_ops used for the VF driver do not expose entry points for
these other features.
These capability bits are in the process of being defeatured from the SI
registers. We should read them from the port capability register, where
they are also present, and which is naturally only exposed to the PF.
The change to blame (relevant for stable backports) is the one where
this started being a problem, aka when the kernel started to crash due
to the wrong capability seen by the VF driver.

Currently for single radio devices (ah->num_radio == 1)
ath12k_mac_op_add_interface() creates vdev and later hw scan and
assign_vif_chanctx uses the same. For MLO, vdev create request should carry ML
address which will not be known during ath12k_mac_op_add_interface() as vif
will be marked as ML only after links are added to it.
If hw scan is requested, the vdev will be deleted post hw scan and subsequent
assign_vif_chanctx call will create new vdev with ML address. But in certain
cases assign_vif_chanctx could be called without any prior hw scan request and
reusing the previously created vdev causes a non-ML vdev to be used for an ML
vif and firmware operates the vdev in non-ML mode.
Fix this by deferring vdev creation for interface until hw scan or
assign_vif_chanctx request is received from mac80211.

When a scan request is received, driver selects a link id for which the arvif
can be mapped. Same link is also used for getting the link conf address.
Currently, we return 0 as link id for a non ML vif, which is correct since that
is the default link id. Also when any of the link vif is active and the scan
request is for a channel in the active link we return its link id. But, when we
don't hit both of the above cases (i.e not a ML vif or no active link vif for
the channel is present) we currently return 0 as the link id.
Bu the problemis that this might not work out always, eg., when only one link
(eg. linkid = 1) is added to vif, then we won't find any link conf for link id
0 in the vif resulting in scan failure. During AP bringup, such scan failure
causes bringup issues. Hence avoid sending link id 0 as default. Rather use a
default link for scan and default link address for the same. This scan vdev
will either be deleted if another scan is requested on same vif or when AP is
broughtup on same link or during interface cleanup.

For a frame transmission for an ML vif, mac80211 mentions transmit link id in
the tx control info. Use it to convert the RA/TA to the corresponding link sta
and link vif address before enqueueing the frame for transmission.
For 802.3 data frames, always enqueue the frame on the primary (assoc) link id.
Firmware does the link selection, builds 802.11 header and therefore the address
translation too.
Also ensure right link vif is used for WMI based management transmission and
add comments to document when RCU read lock is held.

When phy_ethtool_set_eee_noneg() detects a change in the LPI
parameters, it attempts to update phylib state and trigger the link
to cycle so the MAC sees the updated parameters.
However, in doing so, it sets phydev->enable_tx_lpi depending on
whether the EEE configuration allows the MAC to generate LPI without
taking into account the result of negotiation.
This can be demonstrated with a 1000base-T FD interface by:
# ethtool --set-eee eno0 advertise 8 # cause EEE to be not negotiated
# ethtool --set-eee eno0 tx-lpi off
# ethtool --set-eee eno0 tx-lpi on
This results in being true, despite EEE not having been negotiated and:
# ethtool --show-eee eno0
EEE status: enabled - inactive
Tx LPI: 250 (us)
Supported EEE link modes: 100baseT/Full
1000baseT/Full
Advertised EEE link modes: 100baseT/Full
1000baseT/Full
Fix this by keeping track of whether EEE was negotiated via a new
eee_active member in struct phy_device, and include this state in
the decision whether phydev->enable_tx_lpi should be set.

In MLD connection, a pairwise key should work on all active links. And, we
take just one entry in security CAM for one pairwise key. (It means we will
reuse one single entry for all links.) Originally, we already applied the
security CAM entry of pairwise key to deflink's address CAM.
However, links can be activated dynamically. So now for pairwise keys, each
rtw89_sta records the IDs of the security CAM entries. Then, when driver is
notified that some links are active via change_sta_links(), we apply target
pairwise keys to them according to the record.
