Commit 823eb2a3 ("PTP: add support for one-shot output") introduced
a new flag for the PTP periodic output request ioctl. This flag is not
currently supported by any driver.

Fix all drivers which implement the periodic output request ioctl to
explicitly reject any request with flags they do not understand. This
ensures that the driver does not accidentally misinterpret the
PTP_PEROUT_ONE_SHOT flag, or any new flag introduced in the future.

This is important for forward compatibility: if a new flag is
introduced, the driver should reject requests to enable the flag until
the driver has actually been modified to support the flag in question.

mlxsw does not support VXLAN devices with a physical device attached and
vetoes such configurations upon enslavement to an offloaded bridge.

Commit 0ce1822c ("vxlan: add adjacent link to limit depth level")
changed the VXLAN device to be an upper of the physical device which
causes mlxsw to veto the creation of the VXLAN device with "Unknown
upper device type".

This is OK as this configuration is not supported, but it prevents us
from testing bad flows involving the enslavement of VXLAN devices with a
physical device to a bridge, regardless if the physical device is an
mlxsw netdev or not.

Adjust the test to use a dummy device as a physical device instead of a
mlxsw netdev.

Previously, hns3 driver just directly send specific setting bit
and mask bits of MAC VLAN switch parameter to the firmware, it
can not be compatible with the old firmware, because the old one
ignores mask bits and covers all bits with new setting bits.
So when running with old firmware, the communication between PF
and VF will fail after resetting or configuring spoof check, since
they will do the MAC VLAN switch parameter configuration.

This patch fixes this problem by reading switch parameter firstly,
then just modifies the corresponding bit and sends it to firmware.

An ESP packet could be decrypted in async mode if the input handler for
this packet returns -EINPROGRESS in xfrm_input(). At this moment the device
reference in skb is held. Later xfrm_input() will be invoked again to
resume the processing.
If the transform state is still valid it would continue to release the
device reference and there won't be a problem; however if the transform
state is not valid when async resumption happens, the packet will be
dropped while the device reference is still being held.
When the device is deleted for some reason and the reference to this
device is not properly released, the kernel will keep logging like:

unregister_netdevice: waiting for ppp2 to become free. Usage count = 1

The issue is observed when running IPsec traffic over a PPPoE device based
on a bridge interface. By terminating the PPPoE connection on the server
end for multiple times, the PPPoE device on the client side will eventually
get stuck on the above warning message.

This patch will check the async mode first and continue to release device
reference in async resumption, before it is dropped due to invalid state.

Afterward the kernel must be rebooted to work properly again.

This happens because it attempts to call nci_recv_frame() with skb == NULL.
However, unlike nxp_nci_fw_recv_frame(), nci_recv_frame() does not have any
NULL checks for skb, causing the NULL pointer dereference.

Change the code to call only nxp_nci_fw_recv_frame() in case of an error.
Make sure to log it so it is obvious that a communication error occurred.

There is a race between driver code that does setup/cleanup of device
and devlink reload operation that in some drivers works with the same
code. Use after free could we easily obtained by running:

while true; do
        echo "0000:00:10.0" >/sys/bus/pci/drivers/mlxsw_spectrum2/bind
        devlink dev reload pci/0000:00:10.0 &
        echo "0000:00:10.0" >/sys/bus/pci/drivers/mlxsw_spectrum2/unbind
done

Fix this by enabling reload only after setup of device is complete and
disabling it at the beginning of the cleanup process.
