This patch addresses pfc_alloc_status array overflow occurring for
send queue index value greater than PFC priority. Queue index can be
greater than supported PFC priority for multiple scenarios (e.g. QoS,
during non zero SMQ allocation for a PF/VF).
In those scenarios the API should return default tx scheduler '0'.
This is causing mbox errors as otx2_get_smq_idx returing invalid smq value.

Currently, pause frame register GMAC_RX_FLOW_CTRL_RFE is not updated
correctly when 'ethtool -A <IFACE> autoneg off rx off tx off' command
is issued. This fix ensures the flow control change is reflected directly
in the GMAC_RX_FLOW_CTRL_RFE register.

IPV6 addresses are purged when setting the number of rx/tx
rings using ethtool -G. The function aq_set_ringparam
calls dev_close, which removes the addresses. As a solution,
call an internal function (aq_ndev_close).

Defines prefixed with "CONFIG" should be limited to proper Kconfig options,
that are introduced in a Kconfig file.
Here, constants for bitmap indices of some configs are defined and these
defines begin with the config's name, and are suffixed with BITMAP_IDX.
To avoid defines prefixed with "CONFIG", name these constants
BITMAP_IDX_FOR_CONFIG_XYZ instead of CONFIG_XYZ_BITMAP_IDX.
No functional change.

The watchdog timer is used to monitor whether the process
of transmitting data is timeout. If we use qlcnic driver,
the dev_watchdog() that is the timer handler of watchdog
timer will call qlcnic_tx_timeout() to process the timeout.
But the qlcnic_tx_timeout() calls msleep(), as a result,
the sleep-in-atomic-context bugs will happen. The processes
are shown below:
(atomic context)
dev_watchdog
qlcnic_tx_timeout
qlcnic_83xx_idc_request_reset
qlcnic_83xx_lock_driver
msleep
---------------------------
(atomic context)
dev_watchdog
qlcnic_tx_timeout
qlcnic_83xx_idc_request_reset
qlcnic_83xx_lock_driver
qlcnic_83xx_recover_driver_lock
msleep
Fix by changing msleep() to mdelay(), the mdelay() is
busy-waiting and the bugs could be mitigated.

"There are a bunch of late fixes that just came in, in particular a

- A regression fix to the IXP42x PCI bus
- A fix for a memory leak on optee, and another one for mach-mxs
- Two fixes for the sunxi rsb bus driver, to address problems with
the shutdown logic
The rest are small but important devicetree fixes for a number of
individual boards, addressing issues across all platforms:
- arm global timer on older rockchip SoCs is unstable and needs to be
disabled in favor of a more reliable clocksource
- Corrections to fix bluetooth, mmc, and networking on a few Rockchip
boards
- at91/sam9g20ek UDC needs a pin controller config change
- an omap board runs into mmc probe errors because of regulator nodes
in the wrong place
- imx8mp-evk has a minor inaccuracy with its pin config, but without

Microchip USB Analyzer can activate the internal termination resistors
by setting the "termination" option ON, or OFF to to deactivate them.
As I've observed, both with my oscilloscope and captured USB packets
below, you must send "0" to turn it ON, and "1" to turn it OFF.
From the schematics in the user's guide, I can confirm that you must
drive the CAN_RES signal LOW "0" to activate the resistors.
Reverse the argument value of usb_msg.termination to fix this.
These are the two commands sequence, ON then OFF.

pci_get_device() will decrease the reference count for the *from*
parameter. So we don't need to call put_device() to decrease the
reference. Let's remove the put_device() in the loop and only decrease
the reference count of the returned 'pdev' for the last loop because it
will not be passed to pci_get_device() as input parameter. We don't need
to check if 'pdev' is NULL because it is already checked inside
pci_dev_put(). Also add pci_dev_put() for the error path.

step 3: modprobe virtio_net failed

virtio_net: probe of virtio0 failed with error -2
The root cause of the problem is that the queues are not
disable on the error handling path when register_netdevice()
fails in virtnet_probe(), resulting in an error "-ENOENT"
returned in the next modprobe call in setup_vq().
virtio_pci_modern_device uses virtqueues to send or
receive message, and "queue_enable" records whether the
queues are available. In vp_modern_find_vqs(), all queues
will be selected and activated, but once queues are enabled
there is no way to go back except reset.
Fix it by reset virtio device on error handling path. This
makes error handling follow the same order as normal device
cleanup in virtnet_remove() which does: unregister, destroy
failover, then reset. And that flow is better tested than
error handling so we can be reasonably sure it works well.

path which remove the macsec rules to deactivate the offload, the
activation path does not include the counter part installation of the
macsec rules.
Fix by using correct bailout condition and when Rx SA changes state to
active then add the relevant macsec rules.
While at it, refine function name to reflect more precisely its role.

The main functionality for this operation is to update the
active state of the Rx security channel (SC) if the new
active setting is different from the current active state
of this Rx SC, however the relevant active state check is
done post updating the current active state to match the
new active state, effectively blocks any offload state
update for the Rx SC in question.
Fix by delay the assignment to be post the relevant check.

When the MACsec netdevice is deleted, all related Rx/Tx HW/SW
states should be released/deallocated, however currently part
of the Rx security channel association data is not cleaned
properly, hence the memory leaks.
Fix by make sure all related Rx Sc resources are cleaned/freed,
while at it improve code by grouping release SC context in a

delete Rx SC operations.

Currently the data path metadata flow id mask wrongly limits the
number of different RX security channels (SC) to 16, whereas in
adding RX SC the limit is "2^16 - 1" this cause an overlap in
metadata flow id once more than 16 RX SCs is added, this corrupts
MACsec RX offloaded flow handling.
Fix by using the correct mask, while at it improve code to use this

If creating bond first and then enabling sriov in switchdev mode,
will hit the following syndrome:
mlx5_core 0000:08:00.0: mlx5_cmd_out_err:778:(pid 25543): CREATE_LAG(0x840) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0x7d49cb), err(-22)
The reason is because the offending patch removes eswitch mode
none. In vf lag, the checking of eswitch mode none is replaced
by checking if sriov is enabled. But when driver enables sriov,
it triggers the bond workqueue task first and then setting sriov
number in pci_enable_sriov(). So the check fails.
Fix it by checking if sriov is enabled using eswitch internal
counter that is set before triggering the bond workqueue task.

In the blamed commit, a rudimentary reallocation procedure for RX buffer
descriptors was implemented, for the situation when their format changes
between normal (no PTP) and extended (PTP).
enetc_hwtstamp_set() calls enetc_close() and enetc_open() in a sequence,
and this sequence loses information which was previously configured in
the TX BDR Mode Register, specifically via the enetc_set_bdr_prio() call.
The TX ring priority is configured by tc-mqprio and tc-taprio, and
affects important things for TSN such as the TX time of packets. The
issue manifests itself most visibly by the fact that isochron --txtime
reports premature packet transmissions when PTP is first enabled on an
enetc interface.
Save the TX ring priority in a new field in struct enetc_bdr (occupies a
2 byte hole on arm64) in order to make this survive a ring reconfiguration.

The transaction buffer is allocated by using the size of the packet buf,
and subtracting two which seems intended to remove the two tags which are
not present in the target structure. This calculation leads to under
counting memory because of differences between the packet contents and the
target structure. The aid_len field is a u8 in the packet, but a u32 in
the structure, resulting in at least 3 bytes always being under counted.
Further, the aid data is a variable length field in the packet, but fixed
in the structure, so if this field is less than the max, the difference is
added to the under counting.
To fix, perform validation checks progressively to safely reach the
next field, to determine the size of both buffers and verify both tags.
Once all validation checks pass, allocate the buffer and copy the data.
This eliminates freeing memory on the error path, as validation checks are
moved ahead of memory allocation.

The first validation check for EVT_TRANSACTION has two different checks
tied together with logical AND. One is a check for minimum packet length,
and the other is for a valid aid_tag. If either condition is true (fails),
then an error should be triggered. The fix is to change && to ||.

Either ublk_can_use_task_work() is true or not, io commands are
forwarded to ublk server in reverse order, since llist_add() is
always to add one element to the head of the list.
Even though block layer doesn't guarantee request dispatch order,
requests should be sent to hardware in the sequence order generated
from io scheduler, which usually considers the request's LBA, and
order is often important for HDD.
So forward io commands in the sequence made from io scheduler by
aligning task work with current io_uring command's batch handling,
and it has been observed that both can get similar performance data
if IORING_SETUP_COOP_TASKRUN is set from ublk server.
