The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache.

If an unsupported interface is passed to the PCS validation callback there
is no need in further link-modes calculations since the resultant array
will be initialized with zeros which will be perceived by the phylink
subsystem as error anyway (see phylink_validate_mac_and_pcs()). Instead
let's explicitly return the -EINVAL error to inform the caller about the
unsupported interface as it's done in the rest of the pcs_validate
callbacks.

In particular the xpcs_soft_reset() and xpcs_do_config() functions
currently return -1 if invalid auto-negotiation mode is specified. That
value might be then passed to the generic kernel subsystems which require
a standard kernel errno value. Even though the erroneous conditions are
very specific (memory corruption or buggy driver implementation) using a
hard-coded -1 literal doesn't seem correct anyway especially when it comes
to passing it higher to the network subsystem or printing to the system
log. Convert the hard-coded error values to -EINVAL then.

There are currently only two methods (xpcs_find_compat() and
xpcs_get_interfaces()) defined in the driver which loop over the available
interfaces. All of them rely on the xpcs_compat::num_interfaces field
value to get the total number of supported interfaces. Thus the interface
arrays are supposed to be filled with actual interface IDs and there is no
need in the dummy terminating ID placed at the end of the arrays.
Based on the above drop the PHY_INTERFACE_MODE_MAX entry from the
xpcs_2500basex_interfaces array and the PHY_INTERFACE_MODE_MAX-based
conditional statement from the xpcs_get_interfaces() method as redundant.

The TI DP83826 PHY can operate between two RMII modes:
- master mode (PHY operates from a 25MHz clock reference)
- slave mode (PHY operates from a 50MHz clock reference)
By default, the operation mode is configured by hardware straps.
Add support to configure the operation mode from within the driver.

The TI DP83826 PHY can operate in either MII mode or RMII mode.
By default, it is configured by straps.
It can also be configured by writing to the bit 5 of register 0x17 - RMII
and Status Register (RCSR).
When phydev->interface is rmii, rmii mode must be enabled, otherwise
mii mode must be set.
This prevents misconfiguration of hw straps.

veth sets NETIF_F_GRO automatically when XDP is enabled,
because both features use the same NAPI machinery.
The logic to clear NETIF_F_GRO sits in veth_disable_xdp() which
is called both on ndo_stop and when XDP is turned off.
To avoid the flag from being cleared when the device is brought
down, the clearing is skipped when IFF_UP is not set.
Bringing the device down should indeed not modify its features.
Unfortunately, this means that clearing is also skipped when
XDP is disabled _while_ the device is down. And there's nothing
on the open path to bring the device features back into sync.
IOW if user enables XDP, disables it and then brings the device
up we'll end up with a stray GRO flag set but no NAPI instances.
We don't depend on the GRO flag on the datapath, so the datapath
won't crash. We will crash (or hang), however, next time features
are sync'ed (either by user via ethtool or peer changing its config).
The GRO flag will go away, and veth will try to disable the NAPIs.
But the open path never created them since XDP was off, the GRO flag
was a stray. If NAPI was initialized before we'll hang in napi_disable().
If it never was we'll crash trying to stop uninitialized hrtimer.
Move the GRO flag updates to the XDP enable / disable paths,
instead of mixing them with the ndo_open / ndo_close paths.
Fixes: d3256efd8e8b ("veth: allow enabling NAPI even without XDP")

Every time the firmware boots we call ath11k_core_qmi_firmware_ready() which
ends up calling ath11k_thermal_register(). So we try to register thermal
devices multiple times. And when we power off the firmware during
suspend/hibernation (implemented in the next patch) we get a warning in resume:
hwmon hwmon4: PM: parent phy0 should not be sleeping
Workaround this similarly like ath11k_mac_register() does by testing
ATH11K_FLAG_REGISTERED.

Both the firmware reset feature and the power management
suspend/resume feature share common power-down and power-up
functionality. One aspect of the power-up functionality is
the handling of the ATH11K_QMI_EVENT_FW_INIT_DONE event.
When this event is received, a call is made to
ath11k_hal_dump_srng_stats(), with the purpose to collect
information that may be useful in debugging the cause of a
firmware reset.
Unfortunately, since this functionality is shared between
both the firmware reset path and the power management
resume path, the kernel log is flooded with messages during
resume. Since these messages are not useful during resume,
and in fact can be confusing and can increase the time it
takes to resume, update the logic to only call
ath11k_hal_dump_srng_stats() during firmware reset.

For non WoW suspend/resume, ath11k host powers down whole hardware
when suspend and powers up it when resume, the code path it goes
through is very like the ath11k reset logic.
In order to reuse that logic, rearrange IRQ handling in the reset
path.

Commit 3ce4f9c3fbb3 ("net/ps3_gelic_net: Add gelic_descr structures") of
6.8-rc1 had a copy-and-paste error where the pointer that holds the
allocated SKB (struct gelic_descr.skb) was set to NULL after the SKB was
allocated. This resulted in a kernel panic when the SKB pointer was
accessed.
This fix moves the initialization of the gelic_descr to before the SKB
is allocated.

tree
Since commit 5d93cfcf7360 ("net: dpaa: Convert to phylink"), we support
the "10gbase-r" phy-mode through a driver-based conversion of "xgmii",
but we still don't actually support it when the device tree specifies
"10gbase-r" proper.
This is because boards such as LS1046A-RDB do not define pcs-handle-names
(for whatever reason) in the ethernet@f0000 device tree node, and the
code enters through this code path:
err = of_property_match_string(mac_node, "pcs-handle-names", "xfi");
// code takes neither branch and falls through
if (err >= 0) {
(...)
} else if (err != -EINVAL && err != -ENODATA) {
goto _return_fm_mac_free;
}
(...)
/* For compatibility, if pcs-handle-names is missing, we assume this
* phy is the first one in pcsphy-handle
*/
err = of_property_match_string(mac_node, "pcs-handle-names", "sgmii");
if (err == -EINVAL || err == -ENODATA)
pcs = memac_pcs_create(mac_node, 0); // code takes this branch
else if (err < 0)
goto _return_fm_mac_free;
else
pcs = memac_pcs_create(mac_node, err);
// A default PCS is created and saved in "pcs"
// This determination fails and mistakenly saves the default PCS
// memac->sgmii_pcs instead of memac->xfi_pcs, because at this
// stage, mac_dev->phy_if == PHY_INTERFACE_MODE_10GBASER.
if (err && mac_dev->phy_if == PHY_INTERFACE_MODE_XGMII)
memac->xfi_pcs = pcs;
else
memac->sgmii_pcs = pcs;
In other words, in the absence of pcs-handle-names, the default
xfi_pcs assignment logic only works when in the device tree we have
PHY_INTERFACE_MODE_XGMII.
By reversing the order between the fallback xfi_pcs assignment and the
"xgmii" overwrite with "10gbase-r", we are able to support both values
in the device tree, with identical behavior.
Currently, it is impossible to make the s/xgmii/10gbase-r/ device tree
conversion, because it would break forward compatibility (new device
tree with old kernel). The only way to modify existing device trees to
phy-interface-mode = "10gbase-r" is to fix stable kernels to accept this
value and handle it properly.
One reason why the conversion is desirable is because with pre-phylink
kernels, the Aquantia PHY driver used to warn about the improper use
of PHY_INTERFACE_MODE_XGMII [1]. It is best to have a single (latest)
device tree that works with all supported stable kernel versions.
Note that the blamed commit does not constitute a regression per se.
Older stable kernels like 6.1 still do not work with "10gbase-r", but
for a different reason. That is a battle for another time.

Added changes to configure serdes phy and mac based on link speed.
Changing serdes phy speed involves multiple register writes for

phy when new speed is different.
For 2500 speed MAC PCS autoneg needs to disabled. Added changes to

Through the routine bond_mii_monitor(), bonding driver inspects and commits
the slave state changes. During the times when slave state change and
failure in aqcuiring rtnl lock happen at the same time, the routine
bond_mii_monitor() reschedules itself to come around after 1 msec to commit
the new state.
During this, it executes the routine bond_miimon_inspect() to re-inspect
the state chane and prints the corresponding slave state on to the console.
Hence we do see a message at every 1 msec till the rtnl lock is acquired
and state chage is committed.
This patch doesn't change how bond functions. It only simply limits this
kind of log flood.

regardless of the RSS indirection setting on the default VNIC.

Allocate and setup the additional VNIC for ntuple filters if this
new method is supported by the firmware. Even though this VNIC is
only used for ntuple filters with direct ring destinations, we still
setup the RSS hash to be identical to the default VNIC so that each
RX packet will have the correct hash in the RX completion. This
VNIC is always at VNIC index BNXT_VNIC_NTUPLE.

On newer chips that support the ring table index method for
ntuple filters, the current scheme of using the same VNIC for
both RSS and ntuple filters will not work in all cases. An
ntuple filter can only be directed to a destination ring if
that destination ring is also in the RSS indirection table.
To support ntuple filters with any arbitratry RSS indirection
table that may only include a subset of the rings, we need to
use a separate VNIC for ntuple filters.
This patch provisions the additional VNIC. The next patch will
allocate additional VNIC from firmware and set it up.

bnxt_check_rings() is called to check if we have enough resource
assets to satisfy the new number of ethtool channels. If the asset
test fails, the ethtool operation will fail gracefully. Otherwise
we will proceed and commit to use the new number of channels. If it
fails to allocate any resources, the chip will fail to come up.
For completeness, check all possible resources before committing to
the new settings. Add the missing ring group and RSS context asset
tests in bnxt_check_rings().

Add RSS context fields to struct bnxt_hw_rings and struct bnxt_hw_resc.
With these, we can now specific the exact number of RSS contexts to
reserve and store the reserved value. The original code relies on
other resources to infer the number of RSS contexts to reserve and the
reserved value is not stored. This improved infrastructure will make
the RSS context accounting more complete and is needed by later
patches.

The current code assumes that every RX ring group and every TX ring
requires a completion ring on P5_PLUS chips. Now that we have the
bnxt_hw_rings structure, add the cp_p5 field so that it can
be explicitly specified. This makes the logic more clear.

The current functions to reserve hardware rings pass in 6 different ring
or resource types as parameters. Add a structure bnxt_hw_rings to
consolidate all these parameters and pass the structure pointer instead
to these functions. Add 2 related helper functions also. This makes
the code cleaner and makes it easier to add new resources to be
reserved.

Because the number of channels to be configured is calculated using the %,
and it results in 0 when there's an exact division, this leads to some
channels not having their tx power configured.

MediaTek's controller driver on COB platform (e.g. MT8188) is
capable of controlling power supplies and reset pin of a component
(e.g. a WIFI chip) in power-on and power-off process.
Due to this optional feature, mt76 need to inform controller
that mt76 need to keep power during suspend. Otherwise WIFI will be
powered off when system enters suspend process.
The "wakeup-source" property was used for the device that need
this to go into suspend mode so that mt76 suspend handler doesn't
fail and the system is able to enter into a suspend state.
An example:
wifi: mt7921@0 {
wifi0{
reg = <0x0000 0 0 0 0>;
wakeup-source;
};
};
