Proxy ARP allows the AP devices to keep track of the hardware address to
IP address mapping of the STA devices within the BSS. When a request for
such information is made (i.e., ARP request, Neighbor Solicitation), the
AP will respond on behalf of the STA device within the BSS. Such
requests could originate from a device within the BSS or also from the
bridge. In the process of the AP replying to the request (i.e., ARP
reply, Neighbor Advertisement), the AP will drop the original request
frame. The relevant STA will not even know that such information was
ever requested.
This feature is a requirement for Hotspot 2.0, and is defined in IEEE
Std 802.11-2012, 10.23.13. While the Proxy ARP support code mainly
resides in the kernel bridge code, in order to optimize the performance
and simplify kernel implementation, the DHCP snooping code was added to
the hostapd.

Add smps_modes field, and let the driver fill it with its supported SMPS
modes (static/dynamic). This will let us start an AP with specific SMPS
mode (e.g., dynamic) that will allow it to reduce its power usage.

The new "bss_load_update_period" parameter can be used to configure
hostapd to advertise its BSS Load element in Beacon and Probe Response
frames. This parameter is in the units of BUs (Beacon Units).
When enabled, the STA Count and the Channel Utilization value will be
updated periodically in the BSS Load element. The AAC is set to 0 sinze
explicit admission control is not supported. Channel Utilization is
calculated based on the channel survey information from the driver and
as such, requires a driver that supports providing that information for
the current operating channel.

It is now possible to run hwsim_test like data connectivity test through
wpa_supplicant/hostapd control interface if CONFIG_TESTING_OPTIONS=y is
used for the build. Test functionality is enabled/disabled at runtime
with "DATA_TEST_CONFIG <1/0>". The "DATA_TEST_TX <dst> <src> <tos>"
command can be used to request a test frame to be transmitted.
"DATA-TEST-RX <dst> <src>" event is generated when the test frame is
received.

This was used to fill in the "PSMP support" subfield that was defined

current drivers that use hostapd for SME either. As such, there is not

libraries (GnuTLS, CryptoAPI, NSS) since the required FIPS 186-2 PRF
function was not implemented. This resulted in somewhat confusing error
messages since the placeholder functions were silently returning an

(including internal SHA-1 implementation) with crypto libraries that do
not implement this in case EAP-SIM/AKA/AKA' is included in the build.

This commit adds an option to optimize AP teardown by leaving the

This optimization option should be used if the driver supports stations
and keys removal when stopping an AP.
For example, the optimization option will always be used for cfg80211
drivers since cfg80211 shall always remove stations and keys when
stopping an AP (in order to support cases where the AP is disabled
without the knowledge of wpa_supplicant/hostapd).
