rtl8xxxu_queue_select() selects the wrong TX queues because it's
reading memory from the wrong address. It expects to find ieee80211_hdr
at skb->data, but that's not the case after skb_push(). Move the call
to rtl8xxxu_queue_select() before the call to skb_push().
Fixes: 26f1fad29ad9 ("New driver: rtl8xxxu (mac80211)")

Add HW and SDIO ids for use with the muRata 1YN (Cypress CYW43439).
Add the firmware mapping structures for the CYW43439 chipset.

The Chuwi Hi8 Pro tablet contains quite generic names in the sys_vendor
and product_name DMI strings, without this patch brcmfmac will try to load:
"brcmfmac43430a0-sdio.Default string-Default string.txt" as nvram file
which is way too generic.
The Chuwi Hi8 Pro uses the same Ampak AP6212 module as the Chuwi Vi8 Plus
and the nvram for the Vi8 Plus is already in linux-firmware, so point
the new DMI nvram filename quirk to the Vi8 Plus nvram file.

Many devices ship with a nvram ccode value of X2/XT/XU/XV/ALL which are
all special world-wide compatibility ccode-s. Most of these world-wide
ccode-s allow passive scan mode only for 2.4GHz channels 12-14,
only enabling them when an AP is seen on them.
Since linux-firmware has moved to the new cyfmac43430-sdio.bin +
cyfmac43430-sdio.clm_blob firmware files this no longer works and
43430 devices using e.g. an X2 ccode fail to connect to an AP on
channel 13.
Add the 43430 chip-id to the list of chips for which to use the ISO3166
country code + rev 0 as fallback in brcmf_translate_country_code() to
fix this.

In preparation for FORTIFY_SOURCE performing run-time destination buffer
bounds checking for memcpy(), refactor the use of struct iwl_calib_result:
- Have struct iwl_calib_result contain struct iwl_calib_cmd since
functions expect to operate on the "data" flex array in "cmd", which
follows the "hdr" member.
- Switch argument passing around to use struct iwl_calib_cmd instead of
struct iwl_calib_hdr to prepare functions to see the "data" member.
- Change iwl_calib_set()'s "len" argument to a size_t since it is always
unsigned and is normally receiving the output of sizeof().
- Add an explicit length sanity check in iwl_calib_set().
- Adjust the memcpy() to avoid copying across the now visible composite
flex array structure.
This avoids the future run-time warning:
memcpy: detected field-spanning write (size 8) of single field "&res->hdr" (size 4)

I get a log line like this every 4 seconds when connected to my AP:
[15650.221468] iwlwifi 0000:09:00.0: Got NSS = 4 - trimming to 2
Looking at the code, this seems to be related to a hardware limitation,
and there's nothing to be done. In an effort to keep my dmesg
manageable, downgrade this error to "debug" rather than "info".

During stress tests with adding VF to namespace and changing vf's
trust there was a race between iavf_reset_task and iavf_close.
Sometimes when IAVF_FLAG_AQ_DISABLE_QUEUES from iavf_close was sent
to PF after reset and before IAVF_AQ_GET_CONFIG was sent then PF
returns error IAVF_NOT_SUPPORTED to disable queues request and
following requests. There is need to get_config before other
aq_required will be send but iavf_close clears all flags, if
get_config was not sent before iavf_close, then it will not be send
at all.
In case when IAVF_FLAG_AQ_GET_OFFLOAD_VLAN_V2_CAPS was sent before
IAVF_FLAG_AQ_DISABLE_QUEUES then there was rtnl_lock deadlock
between iavf_close and iavf_adminq_task until iavf_close timeouts
and disable queues was sent after iavf_close ends.
There was also a problem with sending delete/add filters.
Sometimes when filters was not yet added to PF and in
iavf_close all filters was set to remove there might be a try
to remove nonexistent filters on PF.
Add aq_required_tmp to save aq_required flags and send them after
disable_queues will be handled. Clear flags given to iavf_down
different than IAVF_FLAG_AQ_GET_CONFIG as this flag is necessary
to sent other aq_required. Remove some flags that we don't
want to send as we are in iavf_close and we want to disable
interface. Remove filters which was not yet sent and send del
filters flags only when there are filters to remove.

The driver currently takes an all or nothing approach for device MSI-X
vectors. Meaning if it does not get its full allocation, it will fail and
not load. There is no reason it can't work with a reduced number of MSI-X

MSI-X fallback logic") and, instead, adjust the MSI-X request to make use
of what is available.

By default, even in client mode, hwsim always had all links
active, where it then uses them in a round-robin fashion.
Re-enable that by activating all valid links work right after

The A-MSDU data needs to be stored per-link and aggregated into a single
value for the station. Add a new struct ieee_80211_sta_aggregates in
order to store this data and a new function
ieee80211_sta_recalc_aggregates to update the current data for the STA.
Note that in the non MLO case the pointer in ieee80211_sta will directly
reference the data in deflink.agg, which means that recalculation may be
skipped in that case.

In hwsim we now track when we receive NDP (or other frames
carrying a PM bit) to see if a link should be active, but
then of course we also need to transmit NDPs to at least
set a link to inactive when we deacivate it. Implement that
as well as sending an NDP when we activate a link, which
allows receiving frames before transmitting any.

Add support for hardware timestamps, if the firmware includes it as a
feature via the GS_CAN_FEATURE_HW_TIMESTAMP flag. Check for this
feature during probe, extend the RX expected length if it is and
enable it during open.
The struct classic_can_ts and struct canfd_ts are extended to include
the µs timestamp following data as defined in the firmware. The
timestamp is then captured and set using skb_hwtstamps() on each RX
and TX.
The frame µs timestamp is provided from a 32 bit 1 MHz timer which
rolls over every 4294 seconds, so a cyclecounter, timecounter, and
delayed worker are used to convert the timer into a proper ns
timestamp - same implementation as commit efd8d98dfb900 ("can:
mcp251xfd: add HW timestamp infrastructure").
Hardware timestamps are added to capabilities as commit
b1f6b93e678f ("can: mcp251xfd: advertise timestamping capabilities and

Use kzalloc(...) rather than kcalloc(1, ...) since because the number of
elements we are specifying in this case is 1, kzalloc would accomplish the
same thing and we can simplify. Also refactor how we calculate the sizeof()
as checkstyle for kzalloc() prefers using the variable we are assigning
to versus the type of that variable for calculating the size to allocate.

-EPROBE_DEFER
devm_clk_get() can return -EPROBE_DEFER, so use dev_err_probe() instead of
dev_err() in order to be less verbose in the log.
This also saves a few LoC.
While at it, turn a "goto fail_dev;" at the beginning of the function into
a direct return in order to avoid mixing goto and return, which looks
spurious.

Add 1000BASE-KX interface mode. This 1G backplane ethernet as described in
clause 70. Clause 73 autonegotiation is mandatory, and only full duplex
operation is supported.
Although at the PMA level this interface mode is identical to
1000BASE-X, it uses a different form of in-band autonegation. This
justifies a separate interface mode, since the interface mode (along
with the MLO_AN_* autonegotiation mode) sets the type of autonegotiation
which will be used on a link. This results in more than just electrical
differences between the link modes.
With regard to 1000BASE-X, 1000BASE-KX holds a similar position to
SGMII: same signaling, but different autonegotiation. PCS drivers
(which typically handle in-band autonegotiation) may only support
1000BASE-X, and not 1000BASE-KX. Similarly, the phy mode is used to
configure serdes phys with phy_set_mode_ext. Due to the different
electrical standards (SFI or XFI vs Clause 70), they will likely want to
use different configuration. Adding a phy interface mode for
1000BASE-KX helps simplify configuration in these areas.

Instead of setting the queue depth once during probe, adjust it on the
fly whenever we configure the link. This is a bit unusal, since usually
the DPAA driver calls into the FMAN driver, but here we do the opposite.
We need to add a netdev to struct mac_device for this, but it will soon
live in the phylink config.
I haven't tested this extensively, but it doesn't seem to break
anything. We could possibly optimize this a bit by keeping track of the
last rate, but for now we just update every time. 10GEC probably doesn't
need to call into this at all, but I've added it for consistency.
