clang static analysis reports this problem:
drivers/net/ethernet/marvell/mvneta.c:3465:2: warning:
Attempt to free released memory
kfree(txq->buf);
^~~~~~~~~~~~~~~
When mvneta_txq_sw_init() fails to alloc txq->tso_hdrs,
it frees without poisoning txq->buf. The error is caught
in the mvneta_setup_txqs() caller which handles the error
by cleaning up all of the txqs with a call to
mvneta_txq_sw_deinit which also frees txq->buf.
Since mvneta_txq_sw_deinit is a general cleaner, all of the
partial cleaning in mvneta_txq_sw_deinit()'s error handling
is not needed.

Mbox implementation in octeontx2 driver has three states
alloc, send and reset in mbox response. VF allocate and
sends message to PF for processing, PF ACKs them back and
reset the mbox memory. In some case we see synchronization
issue where after msgs_acked is incremented and before
mbox_reset API is called, if current execution is scheduled
out and a different thread is scheduled in which checks for
msgs_acked. Since the new thread sees msgs_acked == msgs_sent
it will try to allocate a new message and to send a new mbox
message to PF.Now if mbox_reset is scheduled in, PF will see
'0' in msgs_send.
This patch fixes the issue by calling mbox_reset before
incrementing msgs_acked flag for last processing message and
checks for valid message size.

is a hardware linked list of PF and its VF

Refactor KPU related NPC code gathering all configuration data in a
structured format and putting it in one place (npc_profile.h).
This increases readability and makes it easier to extend the profile
configuration (as opposed to jumping between multiple header and source
files).
To do this:
* Gather all KPU profile related data into a single adapter struct.
* Convert the built-in MKEX definition to a structured one to streamline
the MKEX loading.
* Convert LT default register configuration into a structure, keeping
default protocol settings in same file where identifiers for those
protocols are defined.
* Add a single point for KPU profile loading, so that its source may
change in the future once proper interfaces for loading such config
are in place.

Since LD contains LTYPE definitions tweaked toward efficient
NIX_AF_RX_FLOW_KEY_ALG(0..31)_FIELD(0..4) usage, the original location
of NPC_LT_LD_CUSTOM0/1 was aliased with MPLS_IN_* definitions.
Moving custom frame to value 6 and 7 removes the aliasing at the cost of
custom frames being also considered when TCP/UDP RSS algo is configured.
However since the goal of CUSTOM frames is to classify them to a
separate set of RQs, this cost is acceptable.

PCI devices support two variants of the D3 power state: D3hot (main power
present) D3cold (main power removed). Previously struct pci_dev contained:
unsigned int d3_delay; /* D3->D0 transition time in ms */
unsigned int d3cold_delay; /* D3cold->D0 transition time in ms */
"d3_delay" refers specifically to the D3hot state. Rename it to
"d3hot_delay" to avoid ambiguity and align with the ACPI "_DSM for
Specifying Device Readiness Durations" in the PCI Firmware spec r3.2,
sec 4.6.9.
There is no change to the functionality.

Add PCI interface driver for Prestera Switch ASICs family devices, which
provides:
- Firmware loading mechanism
- Requests & events handling to/from the firmware
- Access to the firmware on the bus level
The firmware has to be loaded each time the device is reset. The driver
is loading it from:
/lib/firmware/mrvl/prestera/mvsw_prestera_fw-v{MAJOR}.{MINOR}.img
The full firmware image version is located within the internal header
and consists of 3 numbers - MAJOR.MINOR.PATCH. Additionally, driver has
hard-coded minimum supported firmware version which it can work with:
MAJOR - reflects the support on ABI level between driver and loaded
firmware, this number should be the same for driver and loaded
firmware.
MINOR - this is the minimum supported version between driver and the
firmware.
PATCH - indicates only fixes, firmware ABI is not changed.
Firmware image file name contains only MAJOR and MINOR numbers to make
driver be compatible with any PATCH version.

Marvell Prestera 98DX326x integrates up to 24 ports of 1GbE with 8
ports of 10GbE uplinks or 2 ports of 40Gbps stacking for a largely
wireless SMB deployment.
The current implementation supports only boards designed for the Marvell
Switchdev solution and requires special firmware.
The core Prestera switching logic is implemented in prestera_main.c,
there is an intermediate hw layer between core logic and firmware. It is
implemented in prestera_hw.c, the purpose of it is to encapsulate hw
related logic, in future there is a plan to support more devices with
different HW related configurations.
This patch contains only basic switch initialization and RX/TX support
over SDMA mechanism.
Currently supported devices have DMA access range <= 32bit and require
ZONE_DMA to be enabled, for such cases SDMA driver checks if the skb
allocated in proper range supported by the Prestera device.
Also meanwhile there is no TX interrupt support in current firmware
version so recycling work is scheduled on each xmit.
Port's mac address is generated from the switch base mac which may be
provided via device-tree (static one or as nvme cell), or randomly
generated. This is required by the firmware.

Fixes the following W=1 kernel build warning(s):
drivers/net/ethernet/marvell/pxa168_eth.c:1190:6: warning:
variable 'retval' set but not used [-Wunused-but-set-variable]
1190 | int retval;
| ^~~~~~
Function pxa168_eth_change_mtu() always return zero, so variable 'retval'
is redundant, just remove it.

These are never modified, so constify them to allow the compiler to
place them in read-only memory. This moves about 25kB to read-only
memory as seen by the output of the size command.

In the functions mvpp2_isr_handle_xlg() and
mvpp2_isr_handle_gmac_internal(), the bool variable link is assigned a
true value in the case that a given bit of val is set. However, if the
bit is unset, no value is assigned to link and it is then passed to
mvpp2_isr_handle_link() without being initialised. Fix by assigning to
link the value of the bit test.
Build-tested on x86.

mvneta_swbm_rx_frame()
In order to easily change the rx buffer size, rely on
MVNETA_MAX_RX_BUF_SIZE instead of PAGE_SIZE in mvneta_swbm_rx_frame
routine for rx buffer split. Currently this is not an issue since we set
MVNETA_MAX_RX_BUF_SIZE to PAGE_SIZE - MVNETA_SKB_PAD but it is a good to
have to configure a different rx buffer size.

Add support for receive timestamping. When enabled, the hardware adds
a timestamp into the receive queue descriptor for all received packets
with no filtering. Hence, we can only support NONE or ALL receive
filter modes.
The timestamp in the receive queue contains two bit sof seconds and
the full nanosecond timestamp. This has to be merged with the remainder
of the seconds from the TAI clock to arrive at a full timestamp before
we can convert it to a ktime for the skb hardware timestamp field.

Check the first level interrupt status registers to determine how to
further process the port interrupt. We will need this to know whether
to invoke the link status processing and/or the PTP processing for
both XLG and GMAC.

The link interrupt is used for way more than just the link status; it
comes from a collection of units to do with the port. The Marvell
documentation describes the interrupt as "GOP port X interrupt".
Since we are adding PTP support, and the PTP interrupt uses this,
rename it to be more inline with the documentation.
This interrupt is also mis-named in the DT binding, but we leave that
alone.
