rtl8723ae: Take the FW LPS mode handling out
This appears to trigger a firmware bug and causes severe

This problem was exposed by commit

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.

iwlwifi: mvm: support mac80211 TXQs model
Move to use the new mac80211 TXQs implementation. This has
quite a few benefits for us. We can get rid of the awkward
mapping of DQA to mac80211 queues. We can stop buffering
traffic while waiting for the queue to be allocated. We can
also use mac80211 AMSDUs instead of building it ourselves.
The usage is pretty simple:
Each ieee80211_txq contains iwl_mvm_txq. There is such a
queue for each TID, and one for management frames. We keep
having static AP queues for probes and non-bufferable MMPDUs,
along with broadcast and multicast queues. Those are being
used from the "old" TX invocation path - iwl_mvm_mac_tx.
When there is a new frame in a TXQ, iwl_mvm_mac_wake_tx is
being called, and either invokes the TX path, or allocates
the queue if it does not exist.
Most of the TX path is left untouched, although we can consider
cleaning it up some more, for example get rid of the duplication
of txq_id in both iwl_mvm_txq and iwl_mvm_dqa_txq_info.

mt76: mmio: introduce mt76x02_check_tx_hang watchdog
Port mt76x02_check_tx_hang watchdog from vendor driver in order to
perform a device reset when tx mac/dma logic hangs. Tx mac/dma stuck
has been observed when the device is heavy loaded or in a noisy
environment. Moreover introduce wdt delayed work in order to run
tx_hang watchdog. For the moment run mt76x02_check_tx_hang watchdog
just on mt76x2 devices since the issue has not been observed on mt76x0
driver yet

Do not set bw variable to zero for legacy rates since it is already
initialized to zero. Moreover set nss to 1 just for legacy rates

mt76: add energy detect CCA support to mt76x{0,2}e drivers
Ported from the reference driver. Should fix compliance with ETSI
regulatories on preventing transmission while energy detect values
are above the threshold.
The code has been tested using an ath9k device running tx99 as
noise generator
