wlcore: do not send stop fwlog cmd if fw is hanged

If the driver received a watchdog interrupt then the
assumption is that the fw is hanged. Avoid sending
the stop fwlog command in case of a watchdog recovey
to avoid waiting for the 2 seconds timeout of the command.

nl80211: add new rssi event to indicate beacon loss

Tell userspace about beacon loss event.
This event doesn't replace the deauth/disassoc that
might come if the AP is not available.

The driver can send this event in order to hint
userspace what might follow (which in turn can
use it as roaming trigger).

wlcore: compare ssid_len before comparing ssids

When comparing 2 ssids the ssid_len must be taken
into account. Otherwise, a substring will be treated
as equal.

This bug might cause ssids to get scanned as
public ssids (rather than hidden), resulting in
broadcast probe request (instead of ssid-specific
ones)

wlcore: Fix sdio out-of-sync power state

wl1271_sdio_power_off() manually powers down the card, regardless of the
runtime pm state. If wl1271_sdio_power_on() is called before the card
was suspended by runtime PM, it will not power up the card.

As part of the HW detection, the chip's power is toggled. Since this
happens in the context of probing sdio, the power reference counter will
be higher than zero. As a result, when wl1271_sdio_power_off() is
called, the chip will be powered down while still having a positive
power reference counter. If the interface is quickly activated, the
driver might try to transfer data to a powered off chip.

Fix this by ensuring that wl1271_sdio_power_on() explicitly powers on
the chip in case runtime pm claims the chip is already powered on.

Also verify that the chip is indeed powered on before powering off, to
avoid wrong reference counter values in error cases.

wlcore/wl12xx/wl18xx: introduce quirk to remove TKIP header space

wlcore/wl12xx/wl18xx: handle spare blocks spacials cases per arch

Add a HW op for getting spare blocks.

12xx cards require 2 spare blocks for GEM encrypted SKBs, regardless
of VIFs or keys programmed into the FW.

18xx cards require 2 spare blocks when there are any connected TKIP or
GEM VIFs. For now always return 2 spare blocks, as this works with all
networks. The special case TKIP/GEM functionality is added at a later
patch.

wlcore: add stop reason bitmap for waking/starting queues

Allow the driver to wake/stop the queues for multiple reasons. A queue
is started when no stop-reasons exist.

Convert all wake/stop queue calls to use the new API.

Before, a stopped queue was almost synonymous a high-watermark on Tx.
Remove a bit of code in wl12xx_tx_reset() that relied on it.

Internal packets arriving from mac80211 are also discarded when a queue
is stopped. A notable exception to this is the watermark reason, which
is a "soft"-stop reason. We allow traffic to gradually come to a halt,
but we don't mind spurious packets here and there. This is merely a flow
regulation mechanism.

Based on a similar patch by Eliad Peller <eliadWizery.com>.

wlcore: stop queues on Tx flush

Stop network queues during Tx flush, and also drop other internal
mac80211 packets (mgmt) that may arrive when the queues are stopped.

When flush is done all driver queues are clear, forcefully if needed.

Protect the Tx flush operation with a new mutex, to prevent concurrency
that can mess us queue state.

wlcore/wl12xx/wl18xx: implement op_set_key per HW arch

The 12xx set_key just calls the common wlcore_set_key function, in order
to program the keys into the FW.

The 18xx variant changes the spare block count when a GEM or TKIP
key is set. Also modify the get_spare_blocks HW op for 18xx to return
the correct numbers of spare blocks, according to what is currently
set in FW.
