[ Upstream commit d280233fc86692f495d5e08092e5422bc2f583a8 ]
Before configuring the NIX block, the AF driver initiates the
"NIX block X2P bus calibration" and verifies that NIX interfaces
such as CGX and LBK are active and functioning correctly.
On few silicon variants(CNF10KA and CNF10KB), X2P calibration failures
have been observed on some CGX blocks that are not mapped to the NIX block.
Since both NIX-mapped and non-NIX-mapped CGX blocks share the same
VENDOR,DEVICE,SUBSYS_DEVID, it's not possible to skip probe based on
these parameters.
This patch introuduces "is_cgx_mapped_to_nix" API to detect and skip
probe of non NIX mapped CGX blocks.

[ Upstream commit 25d51ebf0f54f9c2424f28bb29125cf24f120df0 ]
Number of RVU PFs on CN20K silicon have increased to 96 from maximum
of 32 that were supported on earlier silicons. Every RVU PF and VF is
identified by HW using a 16bit PF_FUNC value. Due to the change in
Max number of PFs in CN20K, the bit encoding of this PF_FUNC has changed.
This patch handles the change by using helper functions(using silicon
check) to use PF,VF masks and shifts to support both new silicon CN20K,
OcteonTx series. These helper functions are used in different modules.
Also moved the NIX AF register offset macros to other files which
will be posted in coming patches.

[ Upstream commit a64494aafc56939564e3e9e57f99df5c27204e04 ]
Once driver submits the packets to the hardware, each packet
traverse through multiple transmit levels in the following
order:
SMQ -> TL4 -> TL3 -> TL2 -> TL1
The SMQ supports configurable minimum and maximum packet sizes.
It enters to a hang state, if driver submits packets with
out of bound lengths.
To avoid the same, implement packet length validation before
submitting packets to the hardware. Increment tx_dropped counter
on failure.

[ Upstream commit 8c5d95988c34f0aeba1f34cd5e4ba69494c90c5f ]
Octeontx2/CN10K silicon supports generating a 256-bit key per packet.
The specific fields to be extracted from a packet for key generation
are configurable via a Key Extraction (MKEX) Profile.
The AF driver scans the configured extraction profile to ensure that
fields from upper layers do not overwrite fields from lower layers in
the key.
Example Packet Field Layout:
LA: DMAC + SMAC
LB: VLAN
LC: IPv4/IPv6
LD: TCP/UDP
Valid MKEX Profile Configuration:
LA -> DMAC -> key_offset[0-5]
LC -> SIP -> key_offset[20-23]
LD -> SPORT -> key_offset[30-31]
Invalid MKEX profile configuration:
LA -> DMAC -> key_offset[0-5]
LC -> SIP -> key_offset[20-23]
LD -> SPORT -> key_offset[2-3] // Overlaps with DMAC field
In another scenario, if the MKEX profile is configured to extract
the SPI field from both AH and ESP headers at the same key offset,
the driver rejecting this configuration. In a regular traffic,
ipsec packet will be having either AH(LD) or ESP (LE). This patch
relaxes the check for the same.

RPM --| NIX |

LBK
Each link supports multiple channels for example RPM link supports
16 channels. In case of link oversubsribe, NIX will assert backpressure
on receive channels.
The previous patch considered a single channel per link, resulting in

This patch addresses below issues,
1. Active traffic on the leaf node must be stopped before its send queue
is reassigned to the parent. This patch resolves the issue by marking
the node as 'Inner'.
2. During a system reboot, the interface receives TC_HTB_LEAF_DEL
and TC_HTB_LEAF_DEL_LAST callbacks to delete its HTB queues.
In the case of TC_HTB_LEAF_DEL_LAST, although the same send queue
is reassigned to the parent, the current logic still attempts to update
the real number of queues, leadning to below warnings
New queues can't be registered after device unregistration.

The AF driver assigns reserved MCAM entries (for unicast, broadcast,
etc.) based on the NIXLF number. When a NIXLF is detached, these entries
are disabled.
For example,
PF NIXLF
--------------------
PF0 0
SDP-VF0 1
If the user unbinds both PF0 and SDP-VF0 interfaces and then binds them in
reverse order
PF NIXLF
---------------------
SDP-VF0 0
PF0 1
In this scenario, the PF0 unicast entry is getting corrupted because
the MCAM entry contains stale data (SDP-VF0 ucast data)
This patch resolves the issue by clearing the unicast MCAM entry during
NIXLF detach

time to convert the mvpp2 driver to the new API, so that the
ndo_eth_ioctl() path can be removed completely.
Note that on the !port->hwtstamp condition, the old code used to fall
through in mvpp2_ioctl(), and return either -ENOTSUPP if !port->phylink,
or -EOPNOTSUPP, in phylink_mii_ioctl(). Keep the test for port->hwtstamp
in the newly introduced net_device_ops, but consolidate the error code
to just -EOPNOTSUPP. The other one is documented as NFS-specific, it's
best to avoid it anyway.

When the host loses heartbeat messages from the device,
the driver calls the device-specific ndo_stop function,
which frees the resources. If the driver is unloaded in
this scenario, it calls ndo_stop again, attempting to free
resources that have already been freed, leading to a host
hang issue. To resolve this, dev_close should be called
instead of the device-specific stop function.dev_close
internally calls ndo_stop to stop the network interface
and performs additional cleanup tasks. During the driver
unload process, if the device is already down, ndo_stop
is not called.

The netdevice usage count increases during transmit queue timeouts
because netdev_hold is called in ndo_tx_timeout, scheduling a task
to reinitialize the card. Although netdev_put is called at the end
of the scheduled work, rtnl_unlock checks the reference count during
cleanup. This could cause issues if transmit timeout is called on
multiple queues.

The current API, otx2_xdp_sq_append_pkt, verifies the number of available
descriptors before sending packets to the hardware.
However, for AF_XDP, this check is unnecessary because the batch value
is already determined based on the free descriptors.
This patch introduces a new API, "otx2_xsk_sq_append_pkt" to address this.
Remove the logic for releasing the TX buffers, as it is implicitly handled
by xsk_tx_peek_release_desc_batch

Previously, device driver IPSec offload implementations would fall into
two categories:
1. Those that used xso.dev to determine the offload device.
2. Those that used xso.real_dev to determine the offload device.
The first category didn't work with bonding while the second did.
In a non-bonding setup the two pointers are the same.
This commit adds explicit pointers for the offload netdevice to
.xdo_dev_state_add() / .xdo_dev_state_delete() / .xdo_dev_state_free()
which eliminates the confusion and allows drivers from the first
category to work with bonding.
xso.real_dev now becomes a private pointer managed by the bonding
driver.

The cn10k_free_matchall_ipolicer() calls the cn10k_map_unmap_rq_policer()
for each queue in a for loop without checking for any errors.
Check the return value of the cn10k_map_unmap_rq_policer() function during
each loop, and report a warning if the function fails.

and the Virtual Function (VF) root node at TL2.
This ensure at any given point of time PF traffic gets more priority.

Due to a bug in the current code, the TL2 parent queue index on the

Protect the parser TCAM/SRAM memory, and the cached (shadow) SRAM
information, from concurrent modifications.
Both the TCAM and SRAM tables are indirectly accessed by configuring
an index register that selects the row to read or write to. This means
that operations must be atomic in order to, e.g., avoid spreading
writes across multiple rows. Since the shadow SRAM array is used to
find free rows in the hardware table, it must also be protected in
order to avoid TOCTOU errors where multiple cores allocate the same
row.
This issue was detected in a situation where `mvpp2_set_rx_mode()` ran
concurrently on two CPUs. In this particular case the
MVPP2_PE_MAC_UC_PROMISCUOUS entry was corrupted, causing the
classifier unit to drop all incoming unicast - indicated by the
`rx_classifier_drops` counter.
