The max buffer size of ENETC RX BD is 0xFFFF bytes, so if the PAGE_SIZE
is greater than 128K, ENETC_RXB_DMA_SIZE and ENETC_RXB_DMA_SIZE_XDP will
be greater than 0xFFFF, thus causing a build warning.
This will not cause any practical issues because ENETC is currently only
used on the ARM64 platform, and the max PAGE_SIZE is 64K. So this patch
is only for fixing the build warning that occurs when compiling ENETC
drivers for other platforms.

When bnxt_init_one() fails during initialization (e.g.,
bnxt_init_int_mode returns -ENODEV), the error path calls
bnxt_free_hwrm_resources() which destroys the DMA pool and sets
bp->hwrm_dma_pool to NULL. Subsequently, bnxt_ptp_clear() is called,
which invokes ptp_clock_unregister().
Since commit a60fc3294a37 ("ptp: rework ptp_clock_unregister() to
disable events"), ptp_clock_unregister() now calls
ptp_disable_all_events(), which in turn invokes the driver's .enable()
callback (bnxt_ptp_enable()) to disable PTP events before completing the
unregistration.
bnxt_ptp_enable() attempts to send HWRM commands via bnxt_ptp_cfg_pin()
and bnxt_ptp_cfg_event(), both of which call hwrm_req_init(). This
function tries to allocate from bp->hwrm_dma_pool, causing a NULL
pointer dereference:
bnxt_en 0000:01:00.0 (unnamed net_device) (uninitialized): bnxt_init_int_mode err: ffffffed
KASAN: null-ptr-deref in range [0x0000000000000028-0x000000000000002f]

The framer driver defines framer_pm_runtime_put() to return an int,
but that return value is never used. It also passes the return value
of pm_runtime_put() to the caller which is not very useful.
Returning an error code from pm_runtime_put() merely means that it has
not queued up a work item to check whether or not the device can be
suspended and there are many perfectly valid situations in which that
can happen, like after writing "on" to the devices' runtime PM "control"
attribute in sysfs for one example.
Modify phy_pm_runtime_put() to discard the pm_runtime_put() return
value and change its return type to void.
No intentional functional impact.
This will facilitate a planned change of the pm_runtime_put() return
type to void in the future.

The function usb_tx_block() submits cardp->tx_urb without ensuring that
any previous transmission on this URB has completed. If a second call
occurs while the URB is still active (e.g. during rapid firmware loading),
usb_submit_urb() detects the active state and triggers a warning:
'URB submitted while active'.
Fix this by enforcing serialization: call usb_kill_urb() before
submitting the new request. This ensures the URB is idle and safe to reuse.

The interface specific workqueues are allocated with the interface name
as part of the workqueue name. However when they are allocated, the
interface name has not been allocated, thus the "name" is actually the
pattern for the name "mlan%d". This ends up pretty ugly and could
conflict if multiple interfaces were added.
Allocate the device name earlier and use that to allocate the
workqueues. Also tweak the workqueue name patterns to add a separator
between the prefix and the interface name parts for readability.

RTL822x cannot access MDIO_MMD_VEND2 via MII_MMD_CTRL/MII_MMD_DATA. A
mapping to use paged access needs to be used instead. All other MMD
devices can be accessed as usual.
Implement phy_read_mmd and phy_write_mmd using paged access for
MDIO_MMD_VEND2 in Clause-22 mode instead of relying on
MII_MMD_CTRL/MII_MMD_DATA. This allows eg. rtl822x_config_aneg to work
as expected in case the MDIO bus doesn't support Clause-45 access.

The PTP irq_chip operations use an hardcoded IRQ offset in the bit
logic. This IRQ offset isn't the same on KSZ8463 than on others switches
so it can't use the irq_chip operations.
Convey the interrupt bit offset through a new attribute in struct ksz_irq

The IRQ logic of the KSZ8463 differs from that of other KSZ switches.
It doesn't have a 'mask' register but an 'enable' one instead. The
common IRQ framework can still be used though as soon as we reverse
the logic (using '1' to enable interrupts instead of '0') for KSZ8463
cases.
Move the initialization of the kirq->masked outside of
ksz_irq_common_setup() to keep this function truly common when
IRQ support for the KSZ8463 is added.

In the FW feature table, V0 and V1 was configured by lt, less than. So, V1
flag was also set in the range of V0. However, in RFK_PRE_NOTIFY handling,
rtw89_fw_h2c_rf_pre_ntfy, V1 is tested before V0. Things would process as
V1 even if V0 should be used.

The Wi-Fi 7 RF calibration flow has a new design which mainly affect
MLO cases. Before, old RFK H2C command can just send the used channels
and MLO mode even if there are multiple active links. After, each RFK
H2C command should send one channel corresponding to one active link.
For example, connect MLD AP (channel X) and then activate second link
(channel X + channel Y)
Before:
RFK#1: channel X (path A + path B)
RFK#2: channel X (path A) + channel Y (path B)
After:
RFK#1: channel X (path A + path B)
[set MLO mode to focus on 2nd link/channel]
RFK#2: channel Y (path A + path B)
[set MLO mode back to target case]

This patch fixes the edge case behavior on ifup/ifdown and
linking/unlinking two netdevsim interfaces:
1. unlink two interfaces netdevsim1 and netdevsim2
2. ifdown netdevsim1
3. ifup netdevsim1
4. link two interfaces netdevsim1 and netdevsim2
5. (Now two interfaces are linked in terms of netdevsim peer, but
carrier state of the two interfaces remains DOWN.)
This inconsistent behavior is caused by the current implementation,
which only cares about the "link, then ifup" order, not "ifup, then
link" order. This patch fixes the inconsistency by calling
netif_carrier_on() when two netdevsim interfaces are linked.
This patch fixes buggy behavior on NetworkManager-based systems which
causes the netdevsim test to fail with the following error:
# timeout set to 600
# selftests: drivers/net/netdevsim: peer.sh
# 2025/12/25 00:54:03 socat[9115] W address is opened in read-write mode but only supports read-only
# 2025/12/25 00:56:17 socat[9115] W connect(7, AF=2 192.168.1.1:1234, 16): Connection timed out

# 2025/12/25 00:56:17 socat[9109] W exiting on signal 15
not ok 13 selftests: drivers/net/netdevsim: peer.sh # exit=1
This patch also solves timeout on TCP Fast Open (TFO) test in
NetworkManager-based systems because it also depends on netdevsim's
carrier consistency.

Convert the Google Virtual Ethernet (GVE) driver to use the new
.get_rx_ring_count ethtool operation instead of handling
ETHTOOL_GRXRINGS in .get_rxnfc. This simplifies the code by moving the

The new callback provides the same functionality in a more direct way,
following the ongoing ethtool API modernization.
