db040dfa53 qtnfmac: use struct_size() in kzalloc()
One of the more common cases of allocation size calculations is finding the
size of a structure that has a zero-sized array at the end, along with memory
for some number of elements for that array. For example:

struct foo {
    int stuff;
    void *entry[];
};

instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can now
use the new struct_size() helper:

instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);

This code was detected with the help of Coccinelle.

c2e28ef771 rt2x00: reduce tx power to nominal level on RT6352
Current implementation of RT6352 support provides too high tx power
at least on iPA/eLNA devices. Reduce amplification of variable gain
amplifier by 6dB to match board target power of 17dBm.
Transmited signal strength with this patch is similar to that of
stock firmware or pandorabox firmware. Throughput measured with iperf
improves. Device tested: Xiaomi Miwifi Mini.

487ec49c35 iwlwifi: trigger dump on assert prior to setting the device up
In the regular flow, when we receive an assert, ieee80211_reconfig is
called which reconfig the driver using iwl_mvm_mac_start.
iwl_mvm_mac_start is clearing the restart bit and does dump collection.

Prior to setting the device up, ieee80211_reconfig does not call
iwl_mvm_mac_start since there is nothing to reconfig and we miss the
dump collection of the assert.

solve it by checking the restart bit before we stop the device
and trigger a dump collection in case it is set.

note that we don't need to do it in the fmac case since in fmac
assert flow in iwl_fmac_nic_error we call iwl_fw_dbg_collect_desc
so we can be sure that there will a dump collection in
iwl_fmac_stop_device.

In order to make more sense out of the captured radiotap data e.g.
when the configured AID changes, add the currently configured AID
to the radiotap data as a vendor extension field.

This is made race-free by updating the included value from inside
the RX path (using a notification wait) for the command response
from the firmware, which thus means it's serialized with frame RX.

fba8248e7e iwlwifi: mvm: get rid of tx_path_lock
TX path lock was introduced in order to prevent out of order
invocations of TX.

This can happen in the following flow:

TX path invoked from net dev
Packet dequeued
	TX path invoked from RX path
	Packet dequeued
	Packet TXed
Packet TXed

However, we don't really need a lock. If TX path is already
invoked from some location, other paths can simply abort their
execution, instead of waiting to the first path to finish, and
then discover queue is (likely) empty or stopped.

Replace the lock with an atomic variable to track TX ownership.
This simplifies the locking dependencies between RX and TX paths,
and should improve performance.

e6aeeb4f45 iwlwifi: mvm: clean up LDBG config command usage
Clean up the LDBG config command to not be called "continuous
recording", and while at it actually remove the continuous
recording implementation completely since it was only used for
store & forward architectures.

This also fixes a bug at least in iwl_fw_dbg_buffer_allocation()
because what's now "__le32 type" (matching the firmware) used to
be "__le16 enable_recording", so the buffer allocation config
sub-struct would erroneously have started at the wrong offset.
In the other cases this didn't actually lead to a bug as other
bytes in pad[] were all zeroes, so accessing the 16-bit value as
a 32-bit value wouldn't make a difference (in little endian.)

486af86332 iwlwifi: mvm: read IWL_RX_MPDU_PHY_SHORT_PREAMBLE only for CCK
Due to a general shortage of RX API bits, the firmware is going
to reuse this bit on non-CCK frames to mean something else. Use
it only on CCK frames to prepare for that change.

677837b8b3 iwlwifi: mvm: fix %16 to %016 print format
With just %16, it means 16 characters padding, but we really
don't want to print "0x         1F4547B", but instead want to
have this filled with zeroes, so we need the 0.

c97781d1d9 iwlwifi: iwlmvm: in monitor NDP notif take the NSS from rx_vec
Take the NSS value from 'rx_vec' rather than from 'rate_n_flags'.
The rate_n_flags has only 2 bits for the NSS giving a max of 4SS
(0 = 1SS etc.). Since there may be up to 8SS use the rx_vec which
has 3 bits for the NSS.
While at it, fix the rx_vec array to length of 2.
