Arnd Bergmann 754107e341 arcnet/com20020: add LEDS_CLASS dependency
The newly added led trigger support in the com20020-pci driver causes
build errors when CONFIG_LEDS_CLASS is disabled:

drivers/built-in.o: In function `com20020pci_probe':
(.text+0x185dc4): undefined reference to `devm_led_classdev_register'
(.text+0x185dd8): undefined reference to `devm_led_classdev_register'

This adds a Kconfig dependency to prevent the invalid configurations.
Other drivers appear to be split 50:50 between 'select' and 'depends on'
for this symbol, I picked 'depends on' as I could not find a common
policy and it generally causes fewer problems.

Ayala Beker e420842724 cfg80211: allow AID/listen interval changes for unassociated station
Currently, cfg80211 rejects updates of AID and listen interval parameters
for existing entries. This information is known only at association stage
and as a result it's impossible to update entries that were added
unassociated.
Fix this by allowing updates of these properies for stations that the
driver (or mac80211) assigned unassociated state.

This then fixes mac80211's use of NL80211_FEATURE_FULL_AP_CLIENT_STATE.

Emmanuel Grumbach 730a755017 mac80211: fixup AIFSN instead of disabling WMM
Disabling WMM has a huge impact these days. It implies that
HT and VHT will be disabled which means that the throughput
will be drammatically reduced.
Since the AIFSN is a transmission parameter, we can play a
bit and fix it up to make it compliant with the 802.11
specification which requires it to be at least 2.
Increasing it from 1 to 2 will slightly reduce the
likelyhood to get a transmission opportunity compared to
other clients that would accept to set AIFSN=1, but at
least it will allow HT and VHT which is a huge gain.

Currently, iwlmvm already implements that behaviour; the other
drivers implementing CQM RSSI events may have to be changed.

This behaviour lets userspace know what the current state is
without relying on querying the data which is racy.

the 'any' trigger) or be aborted.

The current code will end up asking the driver to start a new

some memory (from the previous request.)

Eliad Peller 968a76cef3 mac80211: call drv_stop only if driver is started
If drv_start() fails during hw_restart, all the running
interfaces are being closed/stopped, which results in
drv_stop() being called, although the driver was never
started successfully.

This might cause drivers to perform operations on uninitialized
memory (as they assume it was initialized on drv_start)

Consider the local->started flag, and call the driver's stop()
op only if drv_start() succeeded before.

Move drv_start() and drv_stop() to driver-ops.c, as they are no
longer simple wrappers.

Eliad Peller 43d6df007c mac80211: use freezable workqueue for restart work
Requesting hw restart during suspend might result
in the restart work being executed after mac80211
and the hw are suspended.

Solve the race by simply scheduling the restart
work on a freezable workqueue.

Note that there can be some cases of reconfiguration
on resume (besides the hardware restart):

* wowlan is not configured -
    All the interfaces removed were removed on suspend,
    and drv_stop() was called. At this point the driver
    shouldn't expect for hw_restart anyway, so we can
    simply cancel it (on resume).

* wowlan is configured, drv_resume() == 1
    There is no definitive expected behavior in this case,
    as each driver might have different expectations (e.g.
    setting some flags on suspend/restart vs. not handling
    spurious recovery).
    For now, simply let the hw_restart work run again after
    resume, and hope the driver will handle it well (or at
    least initiate another hw restart).
