driver starts (by calibrator) in plt_mode PLT_FEM_DETECT
wlcore inits and starts plt on wl12xx
wl12xx fetches fem number from firmware and stores it in wl->fem_manuf
wl12xx immediatly returns (doesn't start radio, etc...)

wlcore needs to wait for certain events for example
for roc complete event. Usually the events are received
from the FW very fast, therefore wlcore can poll with
a short delay and if after a second the event was
not received yet poll with a long (1-5 msec) delay.
This implementation is similar to the sending of
commands to the FW.
Empirically the change reduced the wait for roc event
from ~10-40msec to 100s of usecs.

The interrupt line is disabled in op_stop using disable_irq. Since
pending interrupts are synchronized, the mutex has to be released before
disabling the interrupt to avoid a deadlock with the interrupt handler.
In addition, the internal state of the driver is only set to 'off'
after the interrupt is disabled. Otherwise, if an interrupt fires after
the state is set but before the interrupt line is disabled, the
interrupt handler will not be able to acknowledge the interrupt
resulting in an interrupt storm.
The driver's operations might be called during recovery. If these
acquire the mutex after it was released by op_stop, but before the
driver's state is changed, they may queue new work items instead of just
failing. This is especially problematic in the case of scans, in which a
new scan may be scheduled after all scan requests were cancelled.

wl12xx_sdio_power_off() manually powers down the card regardless of the
runtime pm state. If wl12xx_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 wl12xx_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 wl12xx_sdio_power_on() explicitly powers on
the chip in case runtime pm claims the chip is already powered on. To
avoid cases in which it is not possible to determine if the chip was
really powered on (card's power reference counter is positive), operate
on the mmc_card instead of the function.
Also verify that the chip is indeed powered on before powering off, to

FW uses a few memory blocks as a buffer to accumulate FW logs before
transmitting them to the host over SDIO. When FW WatchDog recovery
occurs, the last FW traces are still pending in the buffer. Driver is
to read these FW traces whether log mode is continuous or on demand.
FW memory blocks allocated for the log buffer are handled as a link list:
the first 4 bytes in each memory block contain FW address to the next block.
The end of list condition depends on FW log mode:
- on demand: the list is cyclic, the next address is equal to the first address
- continuous: the address is equal to 0x2000000
Log data resides inside FW memory block with offset depending on
logger mode:
- on demand: 4 bytes (address of the next memory block)
- continuous: 4 bytes and Rx Descriptor structure size

Always report beacon loss to the stack, not only when in powersave
state. This is because there's possibility that the driver disables
PSM before it handles old BSS_LOSE_EVENT, so beacon loss has to be
reported.

Add support for HP (High Performance TQS fem type 3) and SKW
(fem type 2). This is done by increasing the number of FEM
manufacturers to 4.
Usually FEM parameters from ini file are read from nvs file and
passed to firmware using TEST_CMD_INI_FILE_RADIO_PARAM. Still,
because the nvs file has only place for 2 FEMs, we need to pass the
new FEM types information in one of the available entries.
This is done by mapping new fem types 2,3 to entry 0. This solution
works for manual FEM selection. AutoDetect-FEM still support only
fem types 0 and 1.

EAPOLs are sent at high rates as they are considered

don't respond well to these rates and don't respond with
EAPOL 3/4 consistently. When sending EAPOL 2/4 at 54Mbps
we've seen approx 30% success rate in getting EAPOL 3/4 response
while using 11Mbps we got 100% success.

high rates.
