Do not use a random MAC address for the GAS exchange that is used as
part of the DPP protocol exchange since that would break DPP.
Configurator expects the same MAC address to be used for DPP
Authentication exchange and DPP Configuration exchange (GAS).
Since the DPP Authentication exchange has already used the MAC address
configured on the interface, use of a random address for the GAS
exchange would not provide any additional privacy protection. If a
random MAC address needs to be used for this type of an exchange, that
random address would need to be first configured on the interface before
starting DPP exchange.
This does not change GAS query behavior for any other use case, i.e.,
the gas_rand_mac_addr configuration continues to apply to all the
Interworking/Hotspot 2.0 uses.

$(LIBS) got included twice into the linker command line from $^ and
$(LIBS). The former ended up getting converted based on host CPU rather
than target. Fix that by removing duplication and -lcrypto from $(LIBS).

We have practically started requiring some C99 features, so might as
well finally go ahead and bring in the C99 bool as well.

EVP_PKEY_get0_EC_KEY() compatibility wrapper is used only within
CONFIG_DPP2 blocks, so define it with matching condition.

The static function hostapd_ctrl_check_freq_params() was called only
within #ifdef NEED_AP_MLME block so the function needs to be defined
under matching condition.

This has no changes to the function itself, i.e., it is just moved to a
location that is above the first caller.

If the driver supports control port for EAPOL RX, do not register
l2_packet for RX to minimize unnecessary operation load.

drv->eapol_sock is used only for receiving EAPOL frames in AP mode, so
it is not needed when using control port for EAPOL frame RX.

The eloop_register_read_sock() call in i802_init() will be skipped if
the driver supports control port for EAPOL RX, so need to skip this part
of the test case conditionally.

There is no need for this to be outside the if block that is used to
check whether l2_packet is used for the interface.

This allows wpa_supplicant to avoid the packet socket workaround for
cases where a bridge interface is used if the driver supports control
port for EAPOL frame TX and RX.

Since this nl80211 mechanism for sending EAPOL frames does not currently
support TX status notification, disable it by default of AP mode where
the Authenticator state machine uses those notifications to optimize
retransmission. The control port TX can be enabled for AP mode with
driver param control_port_ap=1.

Use and/or set socker owner where necessary to allow EAPOL frames to be
received using the nl80211 control port. This is done when the driver
indicates support for the control port without previous hardcoded
reception of RSN preauth frames.
Use methods which set or use the connection owner nl_sock * where
necessary. Initial operations need to register with the SOCKET_OWNER
attribute set (e.g., connect for STA mode). Final operations need to use
the socket which holds the owner attribute (e.g., disconnect for STA
mode).

This commit creates a connect nl_sock * for every bss unconditionally.
It is used in the next commit for nl80211 control port RX.

nl80211 control port event handling previously did not differentiate
between EAPOL and RSN preauth ethertypes. Add checking of the ethertype
and report unexpected frames (only EAPOL frames are supposed to be
delivered through this path).

This is needed since the initial implementation of the control port
mechanism in the kernel mixed in RSN pre-authentication ethertype
unconditionally (and IMHO, incorrectly) into the control port.
