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

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

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

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.
