Prepare for adding an enum type for NAPI threaded states by adding
netif_threaded_enable API. De-export the existing netif_set_threaded API
and only use it internally. Update existing drivers to use
netif_threaded_enable instead of the de-exported netif_set_threaded.
Note that dev_set_threaded used by mt76 debugfs file is unchanged.

There is no need to store the err string in hw->err_str. Simplify it and
use common helper. hw->err_str is still used for other purpouse.
It should be marked that previously for unknown error the numeric value
was passed as a string. Now the "LIBIE_AQ_RC_UNKNOWN" is used for such
cases.
Add libie_aminq module in i40e Kconfig.

Add a new module for common handling of Admin Queue related logic.
Start by a helper for error to string conversion. This lives inside
libie/, but is a separate module what follows our logic of splitting
into topical modules, to avoid pulling in not needed stuff, and have
better organization in general.
Olek suggested how to better solve the error to string conversion.
It will be used in follow-up patches in ice, i40e and iavf.

The descriptor structure is the same in ice, ixgbe and i40e. Move it to
common libie header to use it across different driver.
Leave device specific adminq commands in separate folders. This lead to
a change that need to be done in filling/getting descriptor:
- previous: struct specific_desc *cmd;
cmd = &desc.params.specific_desc;
- now: struct specific_desc *cmd;
cmd = libie_aq_raw(&desc);
Do this changes across the driver to allow clean build. The casting only
have to be done in case of specific descriptors, for generic one union
can still be used.
Changes beside code moving:
- change ICE_ prefix to LIBIE_ prefix (ice_ and libie_ too)
- remove shift variables not otherwise needed (in libie_aq_flags)
- fill/get descriptor data based on desc.params.raw whenever the
descriptor isn't defined in libie
- move defines from the libie_aq_sth structure outside
- add libie_aq_raw helper and use it instead of explicit casting

The SMMU engine on HIP09 chip has a hardware issue.
SMMU pagetable prefetch features may prefetch and use a invalid PTE
even the PTE is valid at that time. This will cause the device trigger
fake pagefaults. The solution is to avoid prefetching by adding a
SYNC command when smmu mapping a iova. But the performance of nic has a
sharp drop. Then we do this workaround, always enable tx bounce buffer,
avoid mapping/unmapping on TX path.
This issue only affects HNS3, so we always enable
tx bounce buffer when smmu enabled to improve performance.

While at it, add a helper, pp_page_to_nmdesc() and __pp_page_to_nmdesc(),
that can be used to get netmem_desc from page only if it's a pp page.
For now that netmem_desc overlays on page, it can be achieved by just
casting, and use macro and _Generic to cover const casting as well.
Plus, change page_pool_page_is_pp() to check for 'const struct page *'
instead of 'struct page *' since it doesn't modify data and additionally

From Yishai:
This patch series introduces a new DMA Handle (DMAH) object, along with
corresponding APIs for its allocation and deallocation.
The DMAH object encapsulates attributes relevant for DMA transactions.
While initially intended to support TLP Processing Hints (TPH) [1], the
design is extensible to accommodate future features such as PCI
multipath for DMA, PCI UIO configurations, traffic class selection, and
more.
Additionally, we introduce a new ioctl method on the MR object:
UVERBS_METHOD_REG_MR.
This method consolidates multiple reg_mr variants under a single
user-space ioctl interface, supporting: ibv_reg_mr(), ibv_reg_mr_iova(),
ibv_reg_mr_iova2() and ibv_reg_dmabuf_mr(). It also enables passing a
DMA handle as part of the registration process.
Throughout the patch series, the following DMAH-related stuff can also
be observed in the IB layer:
- Association with a CPU ID and its memory type, for use with Steering
Tags [2].
- Inclusion of Processing Hints (PH) data for TPH functionality [3].
- Enforces security by ensuring that only tasks allowed to run on a
given CPU may request a DMA handle for it.
- Reference counting for DMAH life cycle management and safe usage
across memory regions.
mlx5 driver implementation:
--------------------------
The series includes implementation of the above functionality in the
mlx5 driver.
In mlx5_core:
- Enables TPH over PCIe when both firmware and OS support it.
- Manages Steering Tags and corresponding indices by writing tag values
to the PCI configuration space.
- Exposes APIs to upper layers (e.g., mlx5_ib) to enable the PCIe TPH
functionality.
In mlx5_ib:
- Adds full support for DMAH operations.
- Utilizes mlx5_core's Steering Tag APIs to derive tag indices from
input.
- Stores the resulting index in a mlx5_dmah structure for use during
MKEY creation with a DMA handle.
- Adds support for allowing MKEYs to be created in conjunction with DMA
handles.
Additional details are provided in the commit messages.
[1] Background, from PCIe specification 6.2.
TLP Processing Hints (TPH)
--------------------------
TLP Processing Hints is an optional feature that provides hints in
Request TLP headers to facilitate optimized processing of Requests that
target Memory Space. These Processing Hints enable the system hardware
(e.g., the Root Complex and/ or Endpoints) to optimize platform
resources such as system and memory interconnect on a per TLP basis.
Steering Tags are system-specific values used to identify a processing
resource that a Requester explicitly targets. System software discovers
and identifies TPH capabilities to determine the Steering Tag allocation
for each Function that supports TPH
[2] Steering Tags
Functions that intend to target a TLP towards a specific processing
resource such as a host processor or system cache hierarchy require
topological information of the target cache (e.g., which host cache).
Steering Tags are system-specific values that provide information about
the host or cache structure in the system cache hierarchy. These values
are used to associate processing elements within the platform with the
processing of Requests.
[3] Processing Hints
The Requester provides hints to the Root Complex or other targets about
the intended use of data and data structures by the host and/or device.
The hints are provided by the Requester, which has knowledge of upcoming
Request patterns, and which the Completer would not be able to deduce
autonomously (with good accuracy)

Request TLP headers to facilitate optimized processing of Requests that
target Memory Space. These Processing Hints enable the system hardware
(e.g., the Root Complex and/or Endpoints) to optimize platform
resources such as system and memory interconnect on a per TLP basis.
Steering Tags are system-specific values used to identify a processing
resource that a Requester explicitly targets. System software discovers
and identifies TPH capabilities to determine the Steering Tag allocation
for each Function that supports TPH.
This patch adds steering tag support for mlx5 based NICs by:
- Enabling the TPH functionality over PCI if both FW and OS support it.
- Managing steering tags and their matching steering indexes by
writing a ST to an ST index over the PCI configuration space.
- Exposing APIs to upper layers (e.g.,mlx5_ib) to allow usage of
the PCI TPH infrastructure.
Further details:
- Upon probing of a device, the feature will be enabled based
on both capability detection and OS support.
- It will retrieve the appropriate ST for a given CPU ID and memory
type using the pcie_tph_get_cpu_st() API.
- It will track available ST indices according to the configuration
space table size (expected to be 63 entries), reserving index 0 to
indicate non-TPH use.
- It will assign a free ST index with a ST using the
pcie_tph_set_st_entry() API.
- It will reuse the same index for identical (CPU ID + memory type)
combinations by maintaining a reference count per entry.
- It will expose APIs to upper layers (e.g., mlx5_ib) to allow usage of
the PCI TPH infrastructure.
- SF will use its parent PF stuff.

Octeontx2/CN10k MAC block supports DMAC filters. DMAC filters
can be installed on the interface through ethtool.
When a user installs a DMAC filter, the interface's MAC address
is implicitly added to the filter list. To ensure consistency,
this MAC address must be kept in sync with the pfvf->mac_addr field,
which is used to install MAC-based NPC rules.
This patch updates the pfvf->mac_addr field with the programmed MAC
address and also enables VF interfaces to install DMAC filters.

This patch enables batched RX buffer replenishment in ibmveth by
using the new firmware-supported h_add_logical_lan_buffers() hcall
to submit up to 8 RX buffers in a single call, instead of repeatedly
calling the single-buffer h_add_logical_lan_buffer() hcall.
During the probe, with the patch, the driver queries ILLAN attributes
to detect IBMVETH_ILLAN_RX_MULTI_BUFF_SUPPORT bit. If the attribute is
present, rx_buffers_per_hcall is set to 8, enabling batched replenishment.
Otherwise, it defaults to 1, preserving the original upstream behavior
with no change in code flow for unsupported systems.
The core rx replenish logic remains the same. But when batching
is enabled, the driver aggregates up to 8 fully prepared descriptors
into a single h_add_logical_lan_buffers() hypercall. If any allocation
or DMA mapping fails while preparing a batch, only the successfully
prepared buffers are submitted, and the remaining are deferred for
the next replenish cycle.
If at runtime the firmware stops accepting the batched hcall—e,g,
after a Live Partition Migration (LPM) to a host that does not
support h_add_logical_lan_buffers(), the hypercall returns H_FUNCTION.
In that case, the driver transparently disables batching, resets
rx_buffers_per_hcall to 1, and falls back to the single-buffer hcall
in next future replenishments to take care of these and future buffers.
Test were done on systems with firmware that both supports and
does not support the new h_add_logical_lan_buffers hcall.
On supported firmware, this reduces hypercall overhead significantly
over multiple buffers. SAR measurements showed about a 15% improvement
in packet processing rate under moderate RX load, with heavier traffic
seeing gains more than 30%

Add the RX datapath for AF_XDP zero-copy for DQ RDA. The RX path is
quite similar to that of the normal XDP case. Parallel methods are
introduced to properly handle XSKs instead of normal driver buffers.
To properly support posting from XSKs, queues are destroyed and
recreated, as the driver was initially making use of page pool buffers
instead of the XSK pool memory.
Expose support for AF_XDP zero-copy, as the TX and RX datapaths both
exist.

In the descriptor clean path, a number of changes need to be made to
accommodate out of order completions and double completions.
The XSK stack can only handle completions being processed in order, as a
single counter is incremented in xsk_tx_completed to sigify how many XSK
descriptors have been completed. Because completions can come back out
of order in DQ, a separate queue of XSK descriptors must be maintained.
This queue keeps the pending packets in the order that they were written
so that the descriptors can be counted in xsk_tx_completed in the same
order.
For double completions, a new pending packet state and type are
introduced. The new type, GVE_TX_PENDING_PACKET_DQO_XSK, plays an
anlogous role to pre-existing _SKB and _XDP_FRAME pending packet types
for XSK descriptors. The new state, GVE_PACKET_STATE_XSK_COMPLETE,
represents packets for which no more completions are expected. This
includes packets which have received a packet completion or reinjection
completion, as well as packets whose reinjection completion timer have
timed out. At this point, such packets can be counted as part of
xsk_tx_completed() and freed.

Relying on xsk_get_pool_from_qid for getting whether zero copy is
enabled on a queue is erroneous, as an XSK pool is registered in
xp_assign_dev whether AF_XDP zero-copy is enabled or not. This becomes
problematic when queues are restarted in copy mode, as all RX queues
with XSKs will register a pool, causing the driver to exercise the
zero-copy codepath.
This patch adds a bitmap to keep track of which queues have zero-copy
enabled.

The existence of both of these xdp_rxq and xsk_rxq is redundant. xdp_rxq
can be used in both the zero-copy mode and the copy mode case. XSK pool
memory model registration is prioritized over normal memory model

The XDP registration path currently has a lot of reused logic, leading
changes to the codepaths to be unnecessarily complex. gve_reg_xsk_pool
extracts the logic of registering an XSK pool with a queue into a method
that can be used by both XDP_SETUP_XSK_POOL and gve_reg_xdp_info.
gve_unreg_xdp_info is used to undo XDP info registration in the error
path instead of explicitly unregistering the XDP info, as it is more
complete and idempotent.
This patch will be followed by other changes to the XDP registration
logic, and will simplify those changes due to the use of common methods.

gve_tx_timeout was calculating missed completions in a way that is only
relevant in the GQ queue format. Additionally, it was attempting to
disable device interrupts, which is not needed in either GQ or DQ queue
formats.
As a result, TX timeouts with the DQ queue format likely would have
triggered early resets without kicking the queue at all.
This patch drops the check for pending work altogether and always kicks
the queue after validating the queue has not seen a TX timeout too
recently.

On ASP versions v2.x we need to program the TX map vector register to
properly exercise end-to-end flow control, otherwise the TX engine can
either lock-up, or cause the hardware calculated checksum to be
wrong/corrupted when multiple back to back packets are being submitted
for transmission. This register defaults to 0, which means no flow
control being applied.

Unfortunately some systems have left the factory with an uninitialized

So on Tiger Lake platform we ignore the computed checksum when such

When the PF is processing an Admin Queue message to delete a VF's MACs
from the MAC filter, we currently check if the PF set the MAC and if
the VF is trusted.
This results in undesirable behaviour, where if a trusted VF with a
PF-set MAC sets itself down (which sends an AQ message to delete the
VF's MAC filters) then the VF MAC is erased from the interface.
This results in the VF losing its PF-set MAC which should not happen.
There is no need to check for trust at all, because an untrusted VF
cannot change its own MAC. The only check needed is whether the PF set
the MAC. If the PF set the MAC, then don't erase the MAC on link-down.
Resolve this by changing the deletion check only for PF-set MAC.
(the out-of-tree driver has also intentionally removed the check for VF
trust here with OOT driver version 2.26.8, this changes the Linux kernel
driver behaviour and comment to match the OOT driver behaviour)

Currently the tx_dropped field in VF stats is not updated correctly
when reading stats from the PF. This is because it reads from
i40e_eth_stats.tx_discards which seems to be unused for per VSI stats,
as it is not updated by i40e_update_eth_stats() and the corresponding
register, GLV_TDPC, is not implemented[1].
Use i40e_eth_stats.tx_errors instead, which is actually updated by
i40e_update_eth_stats() by reading from GLV_TEPC.
