7d597d4617 AP: Add support for Proxy ARP, DHCP snooping mechanism
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.

ec8f36afca AP: Add support for BSS load element (STA Count, Channel Utilization)
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.

1dde5b5cdd Remove PSMP option from ht_capab
This was used to fill in the "PSMP support" subfield that was defined
during P802.11n development. However, this subfield was marked reserved
in the published IEEE Std 802.11n-2009 and it is not supported by
current drivers that use hostapd for SME either. As such, there is not
much point in maintaining this field as ht_capab parameter within
hostapd either.

configured but the future goal is to implement dynamic TPC algorithm

3f9a8137f5 hostapd: Add a config option to control beaconing
In a AP/STA concurrent setup, if the STA interface is continually
scanning, trying to connect to a network, the AP interface
is basically broken since beaconing would be erratic.

This option can be used in a WDS setup where one AP acts as a
Client/AP-Repeater. The Repeater AP interface has to start beaconing
only after the Client interface has established a WDS link with the
"Root AP".

080585c01a Add support for OCSP stapling to validate server certificate
When using OpenSSL with TLS-based EAP methods, wpa_supplicant can now be
configured to use OCSP stapling (TLS certificate status request) with
ocsp=1 network block parameter. ocsp=2 can be used to require valid OCSP
response before connection is allowed to continue.

hostapd as EAP server can be configured to return cached OCSP response
using the new ocsp_stapling_response parameter and an external mechanism
for updating the response data (e.g., "openssl ocsp ..." command).

This allows wpa_supplicant to verify that the server certificate has not
been revoked as part of the EAP-TLS/PEAP/TTLS/FAST handshake before
actual data connection has been established (i.e., when a CRL could not
be fetched even if a distribution point were specified).

7ca902b53e Make vlan_file optional if dynamic_vlan is used
My APs generate their configuration on their own using a different
number of (vlan-enabled) bss. Currently, all my vlan_file files consist
of a single line: the wildcard line. Configuration file generation would
be easier, if the hostapd configuration file would not depend on those
simple vlan_file files.

This patch removes the need for those one-line files by using the
<device>.<vlan> naming scheme if no vlan_file is given (or that file is
empty). This should not break any existing setup, as using dynamic_vlan
with no vlan configured does not make sense anyway.
