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.

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
this, a debugfs entry is added.
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.

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
data packets. Some APs like Motorola Symbol AP7131 and AP650
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.
To increase the chances of successful 4-Way handshake with
such APs, send EAPOLs with basic rate policy in order to avoid
high rates.

Internal packets arriving from mac80211 are also discarded when a queue
