If the CONFIG_INFINIBAND_IRDMA symbol is not enabled as a module or a
built-in, then don't let the driver reserve resources for RDMA. The result
of this change is a large savings in resources for older kernels, and a
cleaner driver configuration for the IRDMA=n case for old and new kernels.
Implement this by avoiding enabling the RDMA capability when scanning
hardware capabilities.
Note: Loading the out-of-tree irdma driver in connection to the in-kernel
ice driver, is not supported, and should not be attempted, especially when
disabling IRDMA in the kernel config.

On E800 series hardware, if the start time for a periodic output signal is
programmed into GLTSYN_TGT_H and GLTSYN_TGT_L registers, the hardware logic
locks up and the periodic output signal never starts. Any future attempt to
reprogram the clock function is futile as the hardware will not reset until
a power on.
The ice_ptp_cfg_perout function has logic to prevent this, as it checks if
the requested start time is in the past. If so, a new start time is
calculated by rounding up.
Since commit d755a7e129a5 ("ice: Cache perout/extts requests and check
flags"), the rounding is done to the nearest multiple of the clock period,
rather than to a full second. This is more accurate, since it ensures the
signal matches the user request precisely.
Unfortunately, there is a race condition with this rounding logic. If the
current time is close to the multiple of the period, we could calculate a
target time that is extremely soon. It takes time for the software to
program the registers, during which time this requested start time could
become a start time in the past. If that happens, the periodic output
signal will lock up.
For large enough periods, or for the logic prior to the mentioned commit,
this is unlikely. However, with the new logic rounding to the period and
with a small enough period, this becomes inevitable.
For example, attempting to enable a 10MHz signal requires a period of 100
nanoseconds. This means in the *best* case, we have 99 nanoseconds to
program the clock output. This is essentially impossible, and thus such a
small period practically guarantees that the clock output function will
lock up.
To fix this, add some slop to the clock time used to check if the start
time is in the past. Because it is not critical that output signals start
immediately, but it *is* critical that we do not brick the function, 0.5
seconds is selected. This does mean that any requested output will be
delayed by at least 0.5 seconds.
This slop is applied before rounding, so that we always round up to the
nearest multiple of the period that is at least 0.5 seconds in the future,
ensuring a minimum of 0.5 seconds to program the clock output registers.
Finally, to ensure that the hardware registers programming the clock output
complete in a timely manner, add a write flush to the end of
ice_ptp_write_perout. This ensures we don't risk any issue with PCIe
transaction batching.
Strictly speaking, this fixes a race condition all the way back at the
initial implementation of periodic output programming, as it is
theoretically possible to trigger this bug even on the old logic when
always rounding to a full second. However, the window is narrow, and the
code has been refactored heavily since then, making a direct backport not
apply cleanly.

sun8i was using of_get_phy_mode() to set plat_dat->mac_interface, which
defaults to plat_dat->phy_interface when the mac-mode DT property is
not present. As nothing in arch/*/boot/dts sets the mac-mode property,
it is highly likely that these two will be identical, and thus there
is no need for this glue driver to set plat_dat->mac_interface.

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
So, in order to avoid ending up with a flexible-array member in the
middle of multiple other structs, we use the `__struct_group()`
helper to create a new tagged `struct iwl_tx_cmd_hdr`. This structure
groups together all the members of the flexible `struct iwl_tx_cmd`
except the flexible array.
As a result, the array is effectively separated from the rest of the
members without modifying the memory layout of the flexible structure.
We then change the type of the middle struct members currently causing
trouble from `struct iwl_tx_cmd` to `struct iwl_tx_cmd_hdr`.
We also want to ensure that when new members need to be added to the
flexible structure, they are always included within the newly created
tagged struct. For this, we use `static_assert()`. This ensures that the
memory layout for both the flexible structure and the new tagged struct
is the same after any changes.
This approach avoids having to implement `struct iwl_tx_cmd_hdr`
as a completely separate structure, thus preventing having to maintain
two independent but basically identical structures, closing the door
to potential bugs in the future.
So, with these changes, fix the following warnings:
drivers/net/wireless/intel/iwlwifi/dvm/commands.h:2315:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]

This patch resolves an issue where RF calibration data from a
file could not be downloaded to the firmware. The feature to
download calibration data from a file was broken by the commit:
d39fbc88956e.
The issue arose because the function `mwifiex_cmd_cfg_data()`
was modified in a way that prevented proper handling of
file-based calibration data. While this patch restores the ability
to download RF calibration data from a file, it may inadvertently
break the feature to download calibration data from the device
tree. This is because the function `mwifiex_dnld_dt_cfgdata()`,
which also relies on `mwifiex_cmd_cfg_data()`, is still used for
device tree-based calibration data downloads.

iwl_mld_remove_link removes the link from both the FW and from the
driver.
If removing it from the FW failed, we assume that the FW is
dead anyway and remove it from the driver as well.
On the other hand, we still return an error value, indicating the caller
(i.e. mac80211) that the link couldn't be removed - while it was
actually removed.
Later, mac80211 might tell the driver again to remove that link,
and then the driver will warn that it doesn't exist.
Fix this by making iwl_mld_remove_link a void function.

Newer FW can set the CAPS_CHANGE flag during ifup if some capabilities
or configurations have changed. For example, the CoS queue
configurations may have changed. Support this new flag by treating it
almost like FW reset. The driver will essentially rediscover all
features and capabilities, reconfigure all backing store context memory,
reset everything to default, and reserve all resources.

bnxt_hwrm_nvm_req() first searches the nvm_params[] array for the
NVM parameter to set or get. The array entry contains all the

to send the FW message to set or get the parameter.
Refactor it to only do the array search in bnxt_hwrm_nvm_req() and

E610 NICs unlike the previous devices utilising ixgbe driver
are notified in the case of overheating by the FW ACI event.
In event of overheat when threshold is exceeded, FW suspends all
traffic and sends overtemp event to the driver. Then driver
logs appropriate message and disables the adapter instance.
The card remains in that state until the platform is rebooted.
This approach is a solution to the fact current version of the
E610 FW doesn't support reading thermal sensor data by the
SW. So give to user at least any info that overtemp event
has occurred, without interface disappearing from the OS
without any note.

E830 supports raw receive and generic transmit checksum offloads.
Raw receive checksum support is provided by hardware calculating the
checksum over the whole packet, regardless of type. The calculated
checksum is provided to driver in the Rx flex descriptor. Then the driver
assigns the checksum to skb->csum and sets skb->ip_summed to
CHECKSUM_COMPLETE.
Generic transmit checksum support is provided by hardware calculating the
checksum given two offsets: the start offset to begin checksum calculation,
and the offset to insert the calculated checksum in the packet. Support is
advertised to the stack using NETIF_F_HW_CSUM feature.
E830 has the following limitations when both generic transmit checksum
offload and TCP Segmentation Offload (TSO) are enabled:
1. Inner packet header modification is not supported. This restriction
includes the inability to alter TCP flags, such as the push flag. As a
result, this limitation can impact the receiver's ability to coalesce
packets, potentially degrading network throughput.
2. The Maximum Segment Size (MSS) is limited to 1023 bytes, which prevents
support of Maximum Transmission Unit (MTU) greater than 1063 bytes.
Therefore NETIF_F_HW_CSUM and NETIF_F_ALL_TSO features are mutually
exclusive. NETIF_F_HW_CSUM hardware feature support is indicated but is not
enabled by default. Instead, IP checksums and NETIF_F_ALL_TSO are the
defaults. Enforcement of mutual exclusivity of NETIF_F_HW_CSUM and
NETIF_F_ALL_TSO is done in ice_set_features(). Mutual exclusivity
of IP checksums and NETIF_F_HW_CSUM is handled by netdev_fix_features().
When NETIF_F_HW_CSUM is requested the provided skb->csum_start and
skb->csum_offset are passed to hardware in the Tx context descriptor
generic checksum (GCS) parameters. Hardware calculates the 1's complement
from skb->csum_start to the end of the packet, and inserts the result in
the packet at skb->csum_offset.
