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.

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.

Remove VLAN interface on STA free
Currently, vlan_remove_dynamic() is only called when the station VLAN ID
is changed (ap_sta_bind_vlan), but not when the station is freed. So
dynamic VLAN interfaces are not removed actually except within 1x
reauthentification VLAN ID change, although most of the code is already
there.
This patch fixes this by calling vlan_remove_dynamic() in ap_free_sta().
It cannot just use sta->vlan_id for this, as this might have been
changed without calling ap_sta_bind_vlan() (ap/ieee802_11.c:handle_auth
fetches from RADIUS cache for WPA-PSK), thus reference counting might
not have been updated. Additionally, reference counting might get wrong
due to old_vlanid = 0 being passed unconditionally, thus increasing the
reference counter multiple times.
So tracking the currently assigned (i.e., dynamic_vlan counter
increased) VLAN is done in a new variable sta->vlan_id_bound. Therefore,
the old_vlan_id argument of ap_sta_bind_vlan() is no longer needed and
setting the VLAN for the sta in driver happens unconditionally.
Additionally, vlan->dynamic_vlan is only incremented when it actually
is a dynamic VLAN.

Remove VLAN interface on STA free
Currently, vlan_remove_dynamic() is only called when the station VLAN ID
is changed (ap_sta_bind_vlan), but not when the station is freed. So
dynamic VLAN interfaces are not removed actually except within 1x
reauthentification VLAN ID change, although most of the code is already
there.
This patch fixes this by calling vlan_remove_dynamic() in ap_free_sta().
It cannot just use sta->vlan_id for this, as this might have been
changed without calling ap_sta_bind_vlan() (ap/ieee802_11.c:handle_auth
fetches from RADIUS cache for WPA-PSK), thus reference counting might
not have been updated. Additionally, reference counting might get wrong
due to old_vlanid = 0 being passed unconditionally, thus increasing the
reference counter multiple times.
So tracking the currently assigned (i.e., dynamic_vlan counter
increased) VLAN is done in a new variable sta->vlan_id_bound. Therefore,
the old_vlan_id argument of ap_sta_bind_vlan() is no longer needed and
setting the VLAN for the sta in driver happens unconditionally.
Additionally, vlan->dynamic_vlan is only incremented when it actually
is a dynamic VLAN.
