When loading the i40e driver, it prints a message like: 'The driver for the
device detected a newer version of the NVM image v1.x than expected v1.y.
Please install the most recent version of the network driver.' This is
misleading as the driver is working as expected.
Fix that by removing the second part of message and changing it from
dev_info to dev_dbg.

the i40e network card driver to delete its internal mac_filter and

Hide i40e opcode information sent during response to VF in case when
untrusted VF tried to change MAC on the VF interface.
This is implemented by adding an additional parameter 'hide' to the
response sent to VF function that hides the display of error
information, but forwards the error code to VF.
Previously it was not possible to send response with some error code
to VF without displaying opcode information.

PCC OpRegion provides a mechanism to communicate with the platform
directly from the AML. PCCT provides the list of PCC channel available
in the platform, a subset or all of them can be used in PCC Opregion.
This patch registers the PCC OpRegion handler before ACPI tables are
loaded. This relies on the special context data passed to identify and
set up the PCC channel before the OpRegion handler is executed for the
first time.
Typical PCC Opregion declaration looks like this:
OperationRegion (PFRM, PCC, 2, 0x74)
Field (PFRM, ByteAcc, NoLock, Preserve)
{
SIGN, 32,
FLGS, 32,
LEN, 32,
CMD, 32,
DATA, 800
}
It contains four named double words followed by 100 bytes of buffer
names DATA.
ASL can fill out the buffer something like:
/* Create global or local buffer */
Name (BUFF, Buffer (0x0C){})
/* Create double word fields over the buffer */
CreateDWordField (BUFF, 0x0, WD0)
CreateDWordField (BUFF, 0x04, WD1)
CreateDWordField (BUFF, 0x08, WD2)
/* Fill the named fields */
WD0 = 0x50434300
SIGN = BUFF
WD0 = 1
FLGS = BUFF
WD0 = 0x10
LEN = BUFF
/* Fill the payload in the DATA buffer */
WD0 = 0
WD1 = 0x08
WD2 = 0
DATA = BUFF
/* Write to CMD field to trigger handler */
WD0 = 0x4404
CMD = BUFF
This buffer is received by acpi_pcc_opregion_space_handler. This
handler will fetch the complete buffer via internal_pcc_buffer.
The setup handler will receive the special PCC context data which will
contain the PCC channel index which used to set up the channel. The
buffer pointer and length is saved in region context which is then used
in the handler.

This patch prints the cluster node address if a non-cluster node
(according to the dlm config setting) tries to connect. The current
hexdump call will print in a different loglevel and only available if
dynamic debug is enabled. Additional we using the ip address format
strings to print an IETF ip4/6 string represenation.

The current EPB "normal" is defined as 6 and set whenever power-up EPB
value is 0. This setting resulted in the desired out of box power and
performance for several CPU generations. But this value is not suitable
for AlderLake mobile CPUs, as this resulted in higher uncore power.
Since EPB is model specific, this is not unreasonable to have different
behavior.
Allow a capability where "normal" EPB can be redefined. For AlderLake
mobile CPUs this desired normal value is 7.

Return value from regmap_update_bits() directly instead
of taking this in another redundant variable.
