Scheduled scan was disabled because of a bug in the firmware.
The firmware reported support for this feature, but enabling
it led to assertions.
The bugs have been fixes in latest firmware versions, so that
we can re-enable the feature on latest firmwares only.

The variable 'u32 mode' exists twice, the latter shadowing
the former - remove the latter since there's no need for

In commit cad3f08c (iwlwifi: mvm: enable MAC_FILTER_IN_BEACON when
forced_assoc_off is set) the code to set the MAC_FILTER_IN_BEACON flag
was accidentally moved to the main block of the if statement, while it
should be in the else block instead. Move it to the right place.

This code was broken on big endian systems. Sparse didn't
catch the bug since the firmware command was not tagged as
little endian.
Fix the bug for big endian systems and tag the field in the
firmware command to prevent such issues in the future.

When mac80211 requests multiple BSS config changes, as for example
while associating, we ignore power management and QoS changes and
only apply them later. Fix that by removing the "else" and making
the conditions independent.
Also move it after (potential) beacon filter enablement to have
that already enabled when going into power management code.

From: Eyal Shapira <eyal@wizery.com>
Using the LQ table which is initially set according to
the rssi could lead to EAPOLs being sent in high legacy
rates like 54mbps.
It's better to avoid sending EAPOLs in high rates as it reduces
the chances of a successful 4-Way handshake.
Avoid this and treat them like other mgmt frames which would
initially get sent at the basic rate.

The latter is meant for software implementation of power
save and is not per-virtual interface. Since our driver
supports multiple virtual interfaces, we need to use
vif->bss_conf.dtim_period.

smps_mode is used uninitialized in a debug statement in AP
mode, so always initialize it.
While at it, fix a typo.

The idea here is to translate a value of 0 received from
the firmware to the lowest rssi figure. As rx_status->chain_signal
is a signed byte the lowest possible value is -128 and not -256.
-256 was causing 0 to get stored in the signed byte.
