The VF can program the RSS hash configuration over virtchnl. It does this
by sending a u64 bitmask which represents the current hash configuration.
It is not trivial to reverse the hardware configuration back to this hash
set for migration. Instead, save the value to the ice_vf structure when its
modified by the VF.
The rss_hashcfg value is an 8-byte field. Make room for it in ice_vf by
re-arranging some of the existing fields. There is a 4-byte gap after the
first_vector_idx, and a 4-byte gap between max_tx_rate and vf_states. Move
first_vector_idx into the later 4-byte gap, creating an 8 byte area where
rss_hashcfg can be placed. Also move the num_msix field near min_tx_rate,
filling 2 bytes of a 3 byte hole.
The end result of these changes enables placing the rss_hashcfg field into
the structure while also saving 8 bytes in size. It looks like there are a
handful of more possible cleanups to reduce the size even further, but
those have been left as a future cleanup.

The live migration driver will need to save and restore the Tx queue
context state from the hardware registers. This state contains both static
fields which do not change during Tx traffic as well as dynamic fields
which may change during Tx traffic.
Unlike the Rx context, the Tx queue context is accessed indirectly from
GLCOMM_QTX_CNTX_CTL and GLCOMM_QTX_CNTX_DATA registers. These registers are
shared by multiple PFs on the same PCIe card. Multiple PFs cannot safely
access the registers simultaneously, and there is no hardware semaphore or
logic to control access. To handle this, introduce the txq_ctx_lock to the
ice_adapter structure. This is similar to the ptp_gltsyn_time_lock. All PFs
on the same adapter share this structure, and use it to serialize access to
the registers to prevent error.
Add a new functions to get and set the Tx queue context through the
GLCOMM_QTX_CNTX_CTL interface. The hardware context values are stored in
the registers using the same packed format as the Admin Queue buffer.
The hardware buffer is 40 bytes wide, as it contains an additional 18 bytes
of internal state not sent with the Admin Queue buffer. For this reason, a
separate typedef and packing function must be used. We can share the same
packed fields definitions because we never need to unpack the internal
state. This is preferred, as it ensures the internal state is zero'd when
writing into HW, and avoids issues with reading by u32 registers into a
buffer of 22 bytes in length. Thanks to the typedefs, misuse of the API
with the wrong size buffer can easily be caught at compile time.
Note reading this data from hardware is essential because the current Tx
queue context may be different from the context as initially programmed by
the driver during VF initialization. When migrating a VF we must ensure the
target VF has identical context as the source VF did.

Paolo Abeni says:
====================
virtio: introduce GSO over UDP tunnel
Some virtualized deployments use UDP tunnel pervasively and are impacted
negatively by the lack of GSO support for such kind of traffic in the
virtual NIC driver.
The virtio_net specification recently introduced support for GSO over
UDP tunnel, this series updates the virtio implementation to support
such a feature.
Currently the kernel virtio support limits the feature space to 64,
while the virtio specification allows for a larger number of features.
Specifically the GSO-over-UDP-tunnel-related virtio features use bits
65-69.
The first four patches in this series rework the virtio and vhost
feature support to cope with up to 128 bits. The limit is set by
a define and could be easily raised in future, as needed.
This implementation choice is aimed at keeping the code churn as
limited as possible. For the same reason, only the virtio_net driver is
reworked to leverage the extended feature space; all other
virtio/vhost drivers are unaffected, but could be upgraded to support
the extended features space in a later time.
The last four patches bring in the actual GSO over UDP tunnel support.
As per specification, some additional fields are introduced into the
virtio net header to support the new offload. The presence of such
fields depends on the negotiated features.
New helpers are introduced to convert the UDP-tunneled skb metadata to
an extended virtio net header and vice versa. Such helpers are used by
the tun and virtio_net driver to cope with the newly supported offloads.
Tested with basic stream transfer with all the possible permutations of
host kernel/qemu/guest kernel with/without GSO over UDP tunnel support.

In order to support live migration, the ice driver will need to read
certain data from the Rx queue context. This is stored in the hardware in a
packed format.
Since we use <linux/packing.h> for the mapping between the packed hardware
format and the unpacked structure, it is trivial to enable unpacking
support via the unpack_fields() function.
Add the ice_unpack_rxq_ctx() function based on the unpack_fields() API.
Re-use the same field definitions from the packing implementation.
Add ice_copy_rxq_ctx_from_hw() to copy the Rx queue context data from the
hardware registers.
Use these to implement ice_read_rxq_ctx() which will return the Rx queue
context to the caller in its unpacked ice_rlan_ctx struct.
This will enable the migration logic access to the relevant data about the
Rx device queues. It can easily be copied to the target system as part of
the migration payload, where it will be used to configure the Rx queues.

JF device is frozen on API 77. This prevented us from bumping the
minimum FW API of SO (and get rid of older FWs). This is because SO can
be combined with JF and then FW API 77 should be used.
Now as we have separate FW API ranges for the mac and the crf, we can
define for JF its own FW API range. This will allow bumping the minimum
FW API of SO Independently.
Do that now.

Notice how there is no MIPI_SEQ_DEASSERT_RESET, instead the deassert
is done at the beginning of MIPI_SEQ_INIT_OTP, which is exactly what
the fixup from vlv_fixup_mipi_sequences() fixes up.
Extend it to also apply to v2 sequences, this fixes the panel not working

the WMI_BCN_TMPL_CMDID command to firmware.
Check for the beacon protection enabled bit in both tx and non-tx profiles
for MBSSID cases. If set in either profile, enable the beacon protection
feature in firmware for transmitted vif.

Packets delivered to mac80211 from the WBM error path currently do not
have the RX_FLAG_SKIP_MONITOR flag set in status->flag. As a result,
mac80211 performs unnecessary monitor mode checks on each packet, even
though these packets are not intended for monitor mode processing.
In regular rx path, this flag is explicitly set to avoid such overhead.
Align the WBM error path behavior by setting RX_FLAG_SKIP_MONITOR to
prevent redundant per-packet checks in mac80211.

In order to ensure the HTT DebugFS structs shared with firmware have
matching alignment, the structs should be packed. Most of the structs
are correctly packed, however the following are not:
ath12k_htt_tx_pdev_rate_stats_tlv
ath12k_htt_rx_pdev_rate_stats_tlv
ath12k_htt_rx_pdev_rate_ext_stats_tlv
So pack those structs.

The maximum bandwidth an interface can operate in is defined by the
configured country. However, currently, it is able to operate in
bandwidths greater than the allowed bandwidth. For example,
the Central African Republic (CF) supports a maximum bandwidth of 40 MHz
in both the 2 GHz and 5 GHz bands, but an interface is still able to
operate in bandwidths higher than 40 MHz. This issue arises because the
regulatory rules in the regd are not updated with these restrictions
received from firmware on the maximum bandwidth.
Hence, update the regulatory rules with unsupported bandwidth flags based
on the maximum bandwidth to ensure compliance with country-specific
regulations.

This patch provides a setsockopt method to let applications leverage to
adjust how many descs to be handled at most in one send syscall. It
mitigates the situation where the default value (32) that is too small
leads to higher frequency of triggering send syscall.
Considering the prosperity/complexity the applications have, there is no
absolutely ideal suggestion fitting all cases. So keep 32 as its default
value like before.
The patch does the following things:
- Add XDP_MAX_TX_SKB_BUDGET socket option.
- Set max_tx_budget to 32 by default in the initialization phase as a
per-socket granular control.
- Set the range of max_tx_budget as [32, xs->tx->nentries].
The idea behind this comes out of real workloads in production. We use a
user-level stack with xsk support to accelerate sending packets and
minimize triggering syscalls. When the packets are aggregated, it's not
hard to hit the upper bound (namely, 32). The moment user-space stack
fetches the -EAGAIN error number passed from sendto(), it will loop to try
again until all the expected descs from tx ring are sent out to the driver.
Enlarging the XDP_MAX_TX_SKB_BUDGET value contributes to less frequency of
sendto() and higher throughput/PPS.
Here is what I did in production, along with some numbers as follows:
For one application I saw lately, I suggested using 128 as max_tx_budget
because I saw two limitations without changing any default configuration:
1) XDP_MAX_TX_SKB_BUDGET, 2) socket sndbuf which is 212992 decided by
net.core.wmem_default. As to XDP_MAX_TX_SKB_BUDGET, the scenario behind
this was I counted how many descs are transmitted to the driver at one
time of sendto() based on [1] patch and then I calculated the
possibility of hitting the upper bound. Finally I chose 128 as a
suitable value because 1) it covers most of the cases, 2) a higher
number would not bring evident results. After twisting the parameters,
a stable improvement of around 4% for both PPS and throughput and less
resources consumption were found to be observed by strace -c -p xxx:
1) %time was decreased by 7.8%
2) error counter was decreased from 18367 to 572

In reconfig we add the virtual monitor in 2 cases:
1. If we are resuming (it was deleted on suspend)
2. If it was added after an error but before the reconfig
(due to the last non-monitor interface removal).
In the second case, the removal of the non-monitor interface will succeed
but the addition of the virtual monitor will fail, so we add it in the
reconfig.
The problem is that we mislead the driver to think that this is an existing
interface that is getting re-added - while it is actually a completely new
interface from the drivers' point of view.
Some drivers act differently when a interface is re-added. For example, it
might not initialize things because they were already initialized.
Such drivers will - in this case - be left with a partialy initialized vif.
To fix it, add the virtual monitor after reconfig_complete, so the
driver will know that this is a completely new interface.

Before each I2C transfer using DMA, the I2C buffer is DMA'pped to make
sure the memory buffer is DMA'able. This is handle in the function
`stm32_i2c_prep_dma_xfer()`.
If the transfer fails for any reason the I2C buffer must be unmap.
Use the dma_callback to factorize the code and fix this issue.
Note that the `stm32f7_i2c_dma_callback()` is now called in case of DMA
transfer success and error and that the `complete()` on the dma_complete
completion structure is done inconditionnally in case of transfer
success or error as well as the `dmaengine_terminate_async()`.
This is allowed as a `complete()` in case transfer error has no effect
as well as a `dmaengine_terminate_async()` on a transfer success.
Also fix the unneeded cast and remove not more needed variables.

To prevent a potential crash in agg_dequeue (net/sched/sch_qfq.c)
when cl->qdisc->ops->peek(cl->qdisc) returns NULL, we check the return
value before using it, similar to the existing approach in sch_hfsc.c.
To avoid code duplication, the following changes are made:
1. Changed qdisc_warn_nonwc(include/net/pkt_sched.h) into a static
inline function.
2. Moved qdisc_peek_len from net/sched/sch_hfsc.c to
include/net/pkt_sched.h so that sch_qfq can reuse it.
3. Applied qdisc_peek_len in agg_dequeue to avoid crashing.

Avoid calling flush_dcache_folio() on every CPU write, since it's more

It has no impact on x86 and arm64/risc-v: on x86, flush_dcache_folio()
