1b04b739f4 wl12xx: minor fix in sched_scan_ssid_list
The user can pass broadcast SSID (ssid="") in the list of SSIDs for active scan.
In this case the loop was attempting to match SSIDs in the filter
list to this empty entry and marking them as HIDDEN (sending probe
request) by mistake

3dbb5846db wl12xx: send testmode reply in wl1271_tm_cmd_interrogate
wl1271_tm_cmd_interrogate creates a reply skb, but doesn't
send it (and thus just leaks it).
Add the missing cfg80211_testmode_reply() call.

341f2c11b5 wl12xx: avoid bail out when probe-resp is not set by mac80211
During reconfig we can get the BSS_CHANGED_AP_PROBE_RESP indication
even if a probe-resp has not been set in the first place. Therefore
ignore the error when not getting a probe-resp from mac80211. Resort to
the legacy probe-resp in this case.

Also take this opportunity to add a vif argument to the set_probe_resp
function.

state is awake when we do WLAN calibration re-calibrate and we reset
the message exchange between WLAN and BT. BT is given preference when
simultaneous CAL request happens. calibration for WLAN/BT is done
assuming that the other co-existing module is in awake state, if not
we continue to do calibration while if the other module's state changes
we need to do restart the calibration handshake

c27bdc84d6 iwlagn: remove calibration knowledge
The init microcode knows very well which calibrations
are required and sends us results for those that are.
Consequently, we can just send all of those to the RT
uCode again.

The problem with having the driver know about this is
that it is a uCode feature, not a hardware feature so
the config is completely unsuitable.

The only thing we need to check is whether the device
needs crystal calibration or not, add a new parameter
to the configuration for that.

This makes new uCode work on 6000 series devices.

aed666e5e8 iwlwifi: add tm commands for indirect register access
Create new testmode commands to suppot indirect access
of peripheral register.
- IWL_TM_CMD_APP2DEV_INDIRECT_REG_READ32
- IWL_TM_CMD_APP2DEV_INDIRECT_REG_WRITE32

Meanwhile, add affix "DIRECT" into original register access
commands for better discrimination with new commands.
- IWL_TM_CMD_APP2DEV_DIRECT_REG_READ32
- IWL_TM_CMD_APP2DEV_DIRECT_REG_WRITE32
- IWL_TM_CMD_APP2DEV_DIRECT_REG_WRITE8
