This reverts commit 647862eb60.
The second check of device_ap_sme looks like duplicated, but it isn't
actually. The trick is nl80211_create_monitor_interface may change that
variable value and the second evaluation may give a different result.
This definitely isn't a very clear code, but that change caused a
regression for drivers that:
1) Don't report NL80211_ATTR_DEVICE_AP_SME
2) Don't support monitor mode
3) Don't support subscribing for PROBE_REQ and/or ACTION frames
like brcmfmac. With such drivers hostapd doesn't start anymore.

The places using drv->use_monitor were already skipping creation of the
monitor interface if drv->device_ap_sme == 0. This means that the
monitor interface operations would not have worked anyway and it is safe
to set drv->use_monitor to zero for all such cases. This fixes an issue
with management frame subscription not happening properly for the case
where the AP SME is in the driver and the driver supports monitor
interfaces (for other purposes).
This commit also removes the check for monitor support and the
previously used workaround that cleared drv->use_monitor in
drv->device_ap_sme == 1 case if monitor interface was not supported
since that condition cannot occur anymore.

Previously, driver_nl80211 sets NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT in
AP mode, to get EAPOL frames out unencrypted when using IEEE 802.1X/WEP.
However, due to the way nl80211/cfg80211 is implemented, this attribute
is ignored by the kernel if NL80211_ATTR_CONTROL_PORT_ETHERTYPE isn't
specified as well. Fix this by including
NL80211_ATTR_CONTROL_PORT_ETHERTYPE set to ETH_P_PAE. This can be done
unconditionally, since the kernel will allow ETH_P_PAE to be set even
when the driver didn't advertise support for arbitrary ethertypes.
Additionally, the params->pairwise_ciphers appear to not be set at
this point, so relax the check and allow them to be zero.
In client mode, this whole thing was missing, so add it. Again, the
pairwise suite can be WPA_CIPHER_NONE, so allow that case as well.
This fixed IEEE 802.1X/WEP EAP reauthentication and rekeying to use
unencrypted EAPOL frames which is the de facto way of implementing this
in wireless networks.

Previously, the check for mgmt->bssid matching own address (= BSSID)
ended up rejecting the case where Public Action frames are using
Wildcard BSSID in the Address 3 field. This could result in GAS queries
being dropped. Fix this by allowing both the own address (= AP BSSID)
and Wildcard BSSID in Action frame Address 3 field.

This makes wpa_supplicant set default scan IEs to the driver (if the
vendor command is supported). The driver can use these IEs in the scan
requests initiated by the driver itself. Also the driver can merge these
IEs into further scan requests that it receives, in case if the scan
request doesn't carry any of the IEs sent in this command.

During the P802.11s draft development, there were separate LISTEN and
IDLE states. However, the current IEEE 802.11 standards uses only the
IDLE state while the implementation called this LISTEN. Rename the state
in the implementation to match the one used in the standard to avoid
confusion. In addition, rename OPEN_{SENT,RCVD} to OPN_{SNT,RCVD} to
match the exact spelling of these states in the standard.

driver_wired.c pulls in utils/common.h before net/if.h as a workaround
for NetBSD build. This results in IFNAMSIZ getting redefined and sparse
warning about this. Silence that warning by undefining the IFNAMSIZ
definition from common.h to allow the one from net/if.h being used. In
addition, remove duplicated inclusion of net/if.h.

This makes changes such that hostapd (and wpa_supplicant AP mode)
registers to kernel for specific Action frames instead of generically
registering for all Action frames. This makes it easier for other
programs to register for some Action frames that hostapd does not handle
today without having to somehow coordinate directly with hostapd.

One of supported code paths already allows this scenario. It is used if
driver doesn't report NL80211_ATTR_DEVICE_AP_SME and doesn't support
monitor interface. In such situation:
1) We don't quit if subscribing for WLAN_FC_STYPE_PROBE_REQ fails
2) We don't try subscribing for WLAN_FC_STYPE_ACTION
3) We fallback to AP SME mode after failing to create monitor interface
4) We don't quit if subscribing for WLAN_FC_STYPE_PROBE_REQ fails
Above scenario is used, e.g., with brcmfmac. As you can see - thanks to
events provided by cfg80211 - it's not really required to receive Probe
Request or action frames.
However, the previous implementation did not allow using hostapd with
drivers that:
1) Report NL80211_ATTR_DEVICE_AP_SME
2) Don't support subscribing for PROBE_REQ and/or ACTION frames
In case of using such a driver hostapd will cancel setup after failing
to subscribe for WLAN_FC_STYPE_ACTION. I noticed it after setting flag
WIPHY_FLAG_HAVE_AP_SME in brcmfmac driver for my experiments.
This patch allows working with such drivers with just a small warning
printed as debug message.

This struct in the union is empty, but the design of using a zero-length
u8 array here is not fully compatible with C++ and can result in

by using the pointer to the frame header and the known header length.
