Move SA Query mechanism into a file that can be shared more easily This is the first step in allowing SA Query mechanism in hostapd to be used with drivers that implement authentication and association MLME/SME (i.e., do not use ieee802_11.c).

WNM: Add advertisement of BSS max idle period If WNM is enabled for the build (CONFIG_WNM=y), add BSS max idle period information to the (Re)Association Response frame from the AP and parse this information on the station. For SME-in-wpa_supplicant case, add a timer to handle periodic transmission of the keep-alive frame. The actual request for the driver to transmit a frame is not yet implemented.

OCV: Include and verify OCI in SA Query frames Include an OCI element in SA Query Request and Response frames if OCV has been negotiated. On Linux, a kernel patch is needed to let clients correctly handle SA Query Requests that contain an OCI element. Without this patch, the kernel will reply to the SA Query Request itself, without verifying the included OCI. Additionally, the SA Query Response sent by the kernel will not include an OCI element. The correct operation of the AP does not require a kernel patch. Without the corresponding kernel patch, SA Query Requests sent by the client are still valid, meaning they do include an OCI element. Note that an AP does not require any kernel patches. In other words, SA Query frames sent and received by the AP are properly handled, even without a kernel patch. As a result, the kernel patch is only required to make the client properly process and respond to a SA Query Request from the AP. Without this patch, the client will send a SA Query Response without an OCI element, causing the AP to silently ignore the response and eventually disconnect the client from the network if OCV has been negotiated to be used.

On Linux, a kernel patch is needed to let clients correctly handle SA Query Requests that contain an OCI element. Without this patch, the kernel will reply to the SA Query Request itself, without verifying the included OCI. Additionally, the SA Query Response sent by the kernel will not include an OCI element. The correct operation of the AP does not require a kernel patch. Without the corresponding kernel patch, SA Query Requests sent by the client are still valid, meaning they do include an OCI element. Note that an AP does not require any kernel patches. In other words, SA Query frames sent and received by the AP are properly handled, even without a kernel patch. As a result, the kernel patch is only required to make the client properly process and respond to a SA Query Request from the AP. Without this patch, the client will send a SA Query Response without an OCI element, causing the AP to silently ignore the response and eventually disconnect the client from the network if OCV has been negotiated to be used.

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.

WNM: Collocated Interference Reporting Add support for negotiating WNM Collocated Interference Reporting. This allows hostapd to request associated STAs to report their collocated interference information and wpa_supplicant to process such request and reporting. The actual values (Collocated Interference Report Elements) are out of scope of hostapd and wpa_supplicant, i.e., external components are expected to generated and process these. For hostapd/AP, this mechanism is enabled by setting coloc_intf_reporting=1 in configuration. STAs are requested to perform reporting with "COLOC_INTF_REQ <addr> <Automatic Report Enabled> <Report Timeout>" control interface command. The received reports are indicated as control interface events "COLOC-INTF-REPORT <addr> <dialog token> <hexdump of report elements>". For wpa_supplicant/STA, this mechanism is enabled by setting coloc_intf_reporting=1 in configuration and setting Collocated Interference Report Elements as a hexdump with "SET coloc_intf_elems <hexdump>" control interface command. The hexdump can contain one or more Collocated Interference Report Elements (each including the information element header). For additional testing purposes, received requests are reported with "COLOC-INTF-REQ <dialog token> <automatic report enabled> <report timeout>" control interface events and unsolicited reports can be sent with "COLOC_INTF_REPORT <hexdump>". This commit adds support for reporting changes in the collocated interference (Automatic Report Enabled == 1 and partial 3), but not for periodic reports (2 and other part of 3).
