Since the driver can never configure the data here, this field
will always be reported as 0 by the firmware. Even if this was
not the case, however, it wouldn't matter since the extra data
would be added beyond the end of the phy_info structure we use
in the driver, so wouldn't harm anything in this code either.

This message is useless - it's in the good case that always
happens so enabling it doesn't really help. Just remove it.
There are other ways to debug this (e.g. tracing) so there's
no need to add a message in the bad case.

It's possible for an AP interface to be UP but not actually

If we are in d0i3 when entering suspend, we leave d0i3 so that
mac80211 can call us to remove connections or whatever before going to
suspend. We do this by calling pm_runtime_resume() early in the slave
transport flow and reactivating it later, when the wiphy suspend flow
runs.
The problem is that we queue a work in order to leave d0i3. If this
work hasn't run yet when the wiphy suspend flow is called, we have a
race and entering d0i3 fails (because we're still holding the
IWL_MVM_REF_EXIT_WORK reference).
To solve this, simply flush the d0i3_exit_work at the beginning of the
iwl_mvm_suspend() function.

When in AP mode, we need beacons from other APs for HT protection.
However, when there's no any associated station we will not do
any Tx and thus don't really need beacons. On the other hand, these
beacons will cause a lot of unnecessary wakeups which increase our
power consumption. Handle this by asking FW to pass beacons only when
there's at least one associated station.

When receiving statistics notification there is a field of average energy.
This is defines as signed 8 bit, while FW refers to it as unsigned.
when the energy is higher than 127 this causes in iwl_mvm_stat_iterator
a wrong computation of the signal
int sig = -stats->general.beacon_filter_average_energy;
resulting in incorrect CQM event (change from low to high).
While at it - update the rest of the fields to the correct type.

This debugfs entry was implemented just as a proof-of-concept before

Now that we have a proper way to enable netdetect from userspace, this
entry is redundant and should be removed to avoid unnecessary

My static checker complains that we don't check for underflows in
iwl_dbgfs_fw_dbg_conf_write(). This is harmless because we have a
sanity check in iwl_mvm_start_fw_dbg_conf(), but we may as well make
this unsigned and silence the underflow warning.

When we enter D0i3, we must stop TXing otherwise the
sequence number we use might conflict with the firmware's
internal TX. In order to do so, we have
IWL_MVM_STATUS_IN_D0I3 which should prevent any Tx while we
enter D0i3. There is a bug in this code since we may Tx even
if IWL_MVM_STATUS_IN_D0I3 is set. This can happen as long as
mvm->d0i3_ap_sta_id is not set.
To make sure that we don't have any packet in the Tx path
while we set mvm->d0i3_ap_sta_id, call synchronize_net only
after we already set mvm->d0i3_ap_sta_id.

Currently if we wake up during D0I3 due to beacon loss we disconnect
immediately. This behaviour causes redundant disconnection, which could
be prevented by polling as it is usually done in mac80211.
Instead, we prefer reporting beacon loss and let mac80211 try polling
before disconnection.

There is no need to use hex_dump_to_buffer() in the cases like this:
hexdump_to_buffer(buf, len, 16, 1, outbuf, outlen, false); /* len <= 16 */
sprintf("%s\n", outbuf);
since it maybe easily converted to simple:
sprintf("%*ph\n", len, buf);
Note: it seems in one case the output is groupped by 2 bytes and looks like a
typo. Thus, patch changes that to plain byte stream.

The mac80211 patch to pass the NAPI struct only changed iwlwifi to
store the NAPI struct, but we can do better: pass it directly from
the lower transport layer to the opmode during RX, and then on to
mac80211 from there.
When we add multiple RX queues, we can then pass the appropriate
NAPI struct properly.

Lmac sched scan supports partial scans, so we can set some channels to be
scanned on every scan iteration and others to be scanned only on some
iterations. Currently we set all channels to be scanned every iteration,
but still have some configuration of which iterations should be partial
and which should be full.
Remove all partial/full scan configuration to reduce confusions.

Family 8000 products has 2 embedded processors, the first
known as LMAC (lower MAC) and implements the functionality from
previous products, the second one is known as UMAC (upper MAC)
and is used mainly for driver offloads as well as new features.
The UMAC is typically “less” real-time than the LMAC and is used
for higher level controls.
The UMAC's code/data size is estimated to be in the mega-byte arena,
taking into account the code it needs to replace in the driver and
the set of new features.
In order to allow the UMAC to execute code that is bigger than its code
memory, we allow the UMAC embedded processor to page out code pages on
DRAM.
When the device is slave on the bus(SDIO) the driver saves the UMAC's
image pages in blocks of 32K in the DRAM and sends the layout of the
pages to the FW. When the FW wants load / unload pages, it creates an
interrupt, and the driver uploads / downloads the page to an address in
the a specific address on the device's memory.
The driver can support up to 1 MB of pages.
Add paging mechanism for the UMAC on SDIO in order to allow the program to
use a larger virtual space while using less physical memory on the device
itself.
