1e41213fe7 wlcore: read FW logs from FW memory on watchdog recovery
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

Described FW logger API is backward compatible with previous FW versions.

add779a073 wlcore: do not report noise level in get survey op
The get survey op expects the low level driver to report
the noise level for a a given channel.

The noise calculated in wlcore is (rssi-snr/2), but since
the snr reported by the FW is a derivative from the rssi
this calculation is useless, and should not be reported
to the user space.

Reporting incorrect noise, results in the wpa_supplicant
miscalculating the roaming candidate priority, thus causing
a situation where an AP with a lower rssi level would be
chosen over a better AP.

2f18cf7c3b wlcore: reconfigure sleep_auth when removing interfaces
The sleep_auth value of the last interface to be set up prevailed when
an interface was removed. Take care of this by correctly configuring the

Take this opportunity to refactor the sleep_auth setting code for better

66340e5b25 wlcore: allow setting sleep_auth before interface init
Hold a value for sta_sleep_auth that is amenable to change by debugfs.
When detecting a legal value in this variable on interface init, use it
as an override value for sleep_auth.

This makes debugging more intuitive using the debugfs value.

Increment the conf version since we added an element to the conf
structure.

Note: An AP going up will always set sleep_auth to PSM_CAM.

26b5858a67 wlcore: add a debugfs entry to allow changing the sleep mode by hand
For FW debugging purposes, we may need to change the sleep mode
(aka. sleep_auth) by hand, and set it to the mode we want.  To allow

Now we store the sleep_auth value that has been set and use that
instead of the quirk to decide whether we should enter ELP or not.

a2d2bb8675 wl1251: fix filtering support
This driver has a hack in cmd.c which effectively disables all filtering.
This seems to be triggering a firmware bug where it stops reporting any
rx packets after random time on some routers, which is eliminated (or at
least appears much more rarely) when filtering is on.
I have found that only BSSID filter needs to be disabled for association
to work, so disable only that instead of all filtering.

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

we've seen approx 30% success rate in getting EAPOL 3/4 response
while using 11Mbps we got 100% success.

a1c597f2b2 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.
