As the new MLD API is introduced, we have a new enumeration
for the different station types. Since struct iwl_mvm_sta's
sta_type field will be in use for both new and old API,
change its type to a unified one, so it can hold both.

This function sends the STA_HE_CTXT_CMD, which won't be used in the
new MLD API. Instead, a part of the fields of this command
will be in the new STA cmd. Put the parts that are common to both
commands in functions, which will later be used in sending the new
STA cmd.

We used to send a MAC CTXT cmd to ask the FW to not pass MCAST frames
if we're associated but not authorized, because we don't have the
keys in that stage, and after authorization - we sent the cmd again
to ask the FW to pass MCAST, as we have the keys now.
The patch linked below was changing this strategy to always allow
MCAST frames, and if we're not authorized - the driver will drop them.
But we're still sending the MAC CTXT cmd after deaouthorization even
though we don't tell the FW to not pass MCAST frames anymore.
Basically we don't tell the FW anything new with this cmd.
Fix this by not sending MAC CTXT command after deauthorization.
For authorization we're sending the cmd to configure other changes too,
so keep it.

iwl_mvm_get_sync_time() reads the gp2 from the device and then
reads the system clock. Since the two reads are not done atomically,
unexpected delays may happen between the two reads (e.g. context
switch) which make it inaccurate.
In order to improve the accuracy of the cross timestamp, call
iwl_mvm_get_sync_time() multiple times in a loop and take the
result in which the difference between the two clock is the smallest.

Implement the following PHC operations:
1. adjtime - for adding an offset to the PHC clock time.
2. adjfine - for adjusting the PHC clock frequency.
3. gettime64 - for getting the PHC clock time. This function returns
the time as adjusted by adjtime and adjfine.
The adjusted time will also be used for time sync frames timestamping.

For TM/FTM frames, report the hardware timestamps reported by the
fw as part of the RX/TX status. Since the fw reports the timestamps
in a dedicated notification (and not as part of the RX/TX status),
hold the frame until the fw timestamps notification is received.
Timestamping is enabled when a station is connected and disabled
when disconnected. For AP interface, only the first station will
have timestamping enabled since the fw only supports timestamping
for one peer.

This chip is found in cheap "free driver" USB adapters from Aliexpress.
Initially they pretend to be a CD-ROM containing the driver for Windows.
"Ejecting" switches the device to wifi mode.
Features: 2.4 GHz, b/g/n mode, 1T1R, 150 Mbps.
This chip is more unique than other Realtek chips:
* The registers at addresses 0x0-0xff, which all the other chips use,
can't be used here. New registers at 0x8000-0x80ff must be used
instead. And it's not a simple matter of adding 0x8000: 0x2
(REG_SYS_FUNC) became 0x8004, 0x80 (REG_MCU_FW_DL) became 0x8090,
etc.
* Also there are a few new registers which must be accessed indirectly
because their addresses don't fit in 16 bits. No other chips seem to
have these.
* The vendor driver compiles to 8188gu.ko, but the code calls the chip
RTL8710B(U) pretty much everywhere, including messages visible to the
user.
Another difference compared to the other chips supported by rtl8xxxu is
that it has a new PHY status struct, or three of them actually, from
which we extract the RSSI, among other things. This is not unique,
though, just new. The chips supported by rtw88 also use it.

Always run the entire init sequence (rtl8xxxu_init_device()) for
RTL8192EU. It's what the vendor driver does too.
This fixes a bug where the device is unable to connect after
rebooting:
wlp3s0f3u2: send auth to ... (try 1/3)
wlp3s0f3u2: send auth to ... (try 2/3)
wlp3s0f3u2: send auth to ... (try 3/3)
wlp3s0f3u2: authentication with ... timed out
Rebooting leaves the device powered on (partially? at least the
firmware is still running), but not really in a working state.

There are a number of issues here:
* if trans->reduce_power_loaded is already true, we call
iwl_trans_set_reduce_power() with an uninitialized len
value
* in this case we also clobber a previous load/setting
* if iwl_uefi_get_reduced_power() returns an ERR_PTR() we
try to kfree() it
Move the iwl_trans_set_reduce_power() call into the success
case only to fix these issues.

In FW restart scenarios, we allocate the queues from the
iwl_mvm_realloc_queues_after_restart() function, but that
is called before we insert the station ID into our map
(mvm->fw_id_to_mac_id).
However, in all cases where we're actually allocating a
queue for a "real" (not bcast, aux, ...) station we have
the sta pointer already, so just pass it along to use it
instead of looking it up.
This fixes an issue where after restart we only allocated
a queue of size 16 (due to the ordering issue described
above), and thus never got good throughput again since no
aggregates could be formed on transmit.

Commit f79cbc77abde ("wifi: move mac80211_hwsim and virt_wifi to virtual
directory") and commit 298e50ad8eb8 ("wifi: move raycs, wl3501 and
rndis_wlan to legacy directory") move remaining wireless drivers into
subdirectories, but does not adjust the entries in MAINTAINERS.
Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about
broken references.
Repair these file references in those wireless driver sections.

Fix a slab-out-of-bounds read that occurs in kmemdup() called from
brcmf_get_assoc_ies().
The bug could occur when assoc_info->req_len, data from a URB provided
by a USB device, is bigger than the size of buffer which is defined as
WL_EXTRA_BUF_MAX.
Add the size check for req_len/resp_len of assoc_info.
Found by a modified version of syzkaller.

The error map and counter can help to analyze is coexistence mechanism
going well or not. For example, if there is E2G (External control Wi-Fi

Replace the calculations for the payload length in
qtnf_cmd_band_fill_iftype with struct_size() and size_sub(). While
the payload length does not get directly passed to an allocation function,
the performed calculation is still calculating the size of a flexible array
structure (minus the size of a header structure).
