If of_device_register() returns error, the of node and the
name allocated in dev_set_name() is leaked, call put_device()
to give up the reference that was set in device_initialize(),
so that of node is put in logical_port_release() and the name
is freed in kobject_cleanup().

During the bring-up of the Ethernet PHY, it is very useful to

Allow printing the SOR1 register, which contains the strap status

Bond agnostically interacts with TLS device-offload requests via the
.ndo_sk_get_lower_dev operation. Return value is true iff bond
guarantees fixed mapping between the TLS connection and a lower netdev.
Due to this nature, the bond TLS device offload features are not
explicitly controllable in the bond layer. As of today, these are
read-only values based on the evaluation of bond_sk_check(). However,
this indication might be incorrect and misleading, when the feature bits
are "fixed" by some dependency features. For example,
NETIF_F_HW_TLS_TX/RX are forcefully cleared in case the corresponding
checksum offload is disabled. But in fact the bond ability to still
offload TLS connections to the lower device is not hurt.
This means that these bits can not be trusted, and hence better become
unused.
This patch revives some old discussion [1] and proposes a much simpler
solution: Clear the bond's TLS features bits. Everyone should stop
reading them.

It doesn't need extra macros for queue 0 & 4. Same macro could
be used for all 8 queues. Related queue/channel functions could
be combined together.
Original macro which has two same parameters is unsafe macro and
might have potential side effects. Each MTL RxQ DMA channel mask
is 4 bits, so using (0xf << chan) instead of GENMASK(x + 3, x) to
avoid unsafe macro.

RZ/G2L has separate channel specific IRQs for transmit and error
interrupts. But the IRQ handler processes both channels, even if there
no interrupt occurred on one of the channels.
This patch fixes the issue by passing a channel specific context
parameter instead of global one for the IRQ register and the IRQ
handler, it just handles the channel which is triggered the interrupt.

FIFO receive
We are seeing an IRQ storm on the global receive IRQ line under heavy
CAN bus load conditions with both CAN channels enabled.
Conditions:
The global receive IRQ line is shared between can0 and can1, either of
the channels can trigger interrupt while the other channel's IRQ line
is disabled (RFIE).
When global a receive IRQ interrupt occurs, we mask the interrupt in
the IRQ handler. Clearing and unmasking of the interrupt is happening
in rx_poll(). There is a race condition where rx_poll() unmasks the
interrupt, but the next IRQ handler does not mask the IRQ due to
NAPIF_STATE_MISSED flag (e.g.: can0 RX FIFO interrupt is disabled and
can1 is triggering RX interrupt, the delay in rx_poll() processing
results in setting NAPIF_STATE_MISSED flag) leading to an IRQ storm.
This patch fixes the issue by checking IRQ active and enabled before
handling the IRQ on a particular channel.

kvaser_usb uses completions to signal when a response event is received
for outgoing commands.
However, it uses init_completion() to reinitialize the start_comp and
stop_comp completions before sending the start/stop commands.
In case the device sends the corresponding response just before the
actual command is sent, complete() may be called concurrently with
init_completion() which is not safe.
This might be triggerable even with a properly functioning device by
stopping the interface (CMD_STOP_CHIP) just after it goes bus-off (which
also causes the driver to send CMD_STOP_CHIP when restart-ms is off),
but that was not tested.
Fix the issue by using reinit_completion() instead.

The phylib callback is called after MAC driver's own resume callback is
called. For AVE driver, after resuming immediately, PHY state machine is
in PHY_NOLINK because there is a time lag from link-down to link-up due to
autoneg. The result is WARN_ON() dump in mdio_bus_phy_resume().
Since ave_resume() itself calls phy_resume(), AVE driver should manage
PHY PM. To indicate that MAC driver manages PHY PM, set
phydev->mac_managed_pm to true to avoid the unnecessary phylib call and
add missing phy_init_hw() to ave_resume().

request ready for this cycle later on, but I want to get this one out first.
Miquel Raynal added support for sending frames synchronously as a dependency
to handle MLME commands. Also introducing more filtering levels to match with
the needs of a device when scanning or operating as a pan coordinator.
To support development and testing the hwsim driver for ieee802154 was also
enhanced for the new filtering levels and to update the PIB attributes.
Alexander Aring fixed quite a few bugs spotted during reviewing changes. He
also added support for TRAC in the atusb driver to have better failure

When auto-restart is enabled, the kvaser_usb_leaf driver considers
transition from any state >= CAN_STATE_BUS_OFF as a bus-off recovery
event (restart).
However, these events may occur at interface startup time before
kvaser_usb_open() has set the state to CAN_STATE_ERROR_ACTIVE, causing
restarts counter to increase and CAN_ERR_RESTARTED to be sent despite no
actual restart having occurred.
Fix that by making the auto-restart condition checks more strict so that
they only trigger when the interface was actually in the BUS_OFF state.

With 0bfd:0124 Kvaser Mini PCI Express 2xHS FW 4.18.778 it was observed
that if the device was bus-off when stopped, at next start (either via
interface down/up or manual bus-off restart) the initial
CMD_CHIP_STATE_EVENT received just after CMD_START_CHIP_REPLY will have
the M16C_STATE_BUS_OFF bit still set, causing the interface to
immediately go bus-off again.
The bit seems to internally clear quickly afterwards but we do not get
another CMD_CHIP_STATE_EVENT.
Fix the issue by ignoring any initial bus-off state until we see at
least one bus-on state. Also, poll the state periodically until that
occurs.
It is possible we lose one actual immediately occurring bus-off event
here in which case the HW will auto-recover and we see the recovery
event. We will then catch the next bus-off event, if any.
This issue did not reproduce with 0bfd:0017 Kvaser Memorator
Professional HS/HS FW 2.0.50.

kvaser_usb_leaf_rx_error_update_can_state() sets error state according
to error counters when the hardware does not indicate a specific state
directly.
However, this is currently gated behind a check for
M16C_STATE_BUS_ERROR which does not always seem to be set when error
counters are increasing, and may not be set when error counters are
decreasing.
This causes the CAN_STATE_ERROR_WARNING state to not be set in some
cases even when appropriate.
Change the code to set error state from counters even without
M16C_STATE_BUS_ERROR.
The Error-Passive case seems superfluous as it is already set via
M16C_STATE_BUS_PASSIVE flag above, but it is kept for now.

Some resource limits on IPA v3.5.1 have their max values set to
255, this causes a few splats in ipa_reg_encode and prevents the
IPA from booting properly. The limits are all 6 bits wide so
adjust the max values to 63.

Fix setting bits for specific flow_type for GLQF_HASH_INSET register.
In previous version all of the bits were set only in hena register, while
in inset only one bit was set. In order for this working correctly on all
types of cards these bits needs to be set correctly for both hena and inset
registers.

When a reset was triggered on one VF with i40e_reset_vf
global PF state __I40E_VF_DISABLE was set on a PF until
the reset finished. If immediately after triggering reset
on one VF there is a request to reset on another
it will cause a hang on VF side because VF will be notified
of incoming reset but the reset will never happen because
of this global state, we will get such error message:
[ +4.890195] iavf 0000:86:02.1: Never saw reset
and VF will hang waiting for the reset to be triggered.
Fix this by introducing new VF state I40E_VF_STATE_RESETTING
that will be set on a VF if it is currently resetting instead of
the global __I40E_VF_DISABLE PF state.

When enabling flow type for RSS hash via ethtool:
ethtool -N $pf rx-flow-hash tcp4|tcp6|udp4|udp6 s|d
the driver would fail to setup this setting on X722
device since it was using the mask on the register
dedicated for X710 devices.
Apply a different mask on the register when setting the
RSS hash for the X722 device.
When displaying the flow types enabled via ethtool:
ethtool -n $pf rx-flow-hash tcp4|tcp6|udp4|udp6
the driver would print wrong values for X722 device.
Fix this issue by testing masks for X722 device in
i40e_get_rss_hash_opts function.

Verify that the sizes of the routing and filter table memory regions
are valid as part of memory initialization, rather than waiting for
table initialization. The main reason to do this is that upcoming
patches use these memory region sizes to determine the number of
entries in these tables, and we'll want to know these sizes are good
sooner.

What ipa_table_valid() (and ipa_table_valid_one(), which it calls)
does is ensure that the memory regions that hold routing and filter
tables have reasonable size. Specifically, it checks that the size
of a region is sufficient (or rather, exactly the right size) to
hold the maximum number of entries supported by the driver. (There
is an additional check that's erroneous, but in practice it is never
reached.)
Recently ipa_table_mem_valid() was added, which is called by
ipa_table_init(). That function verifies that all table memory
regions are of sufficient size, and requires hashed tables to have
zero size if hashing is not supported. It only ensures the filter
table is large enough to hold the number of endpoints that support
filtering, but that is adequate.
Therefore everything that ipa_table_valid() does is redundant, so
get rid of it.
