Add new configuration parameters macsec_replay_protect and
macsec_replay_window to allow user to set up MACsec replay protection
feature. Note that according to IEEE Std 802.1X-2010 replay protection
and delay protection are different features: replay protection is
related only to SecY and does not appear on MKA level while delay
protection is something that KaY can use to manage SecY state.

The purpose of the Lowest Acceptable PN (lpn) parameters in the MACsec
SAK Use parameter set is to enforce delay protection. Per IEEE Std
802.1X-2010, Clause 9, "Each SecY uses MKA to communicate the lowest PN
used for transmission with the SAK within the last two seconds, allowing
receivers to bound transmission delays."
When encoding the SAK Use parameter set the KaY should set llpn and olpn
to the lowest PN transmitted by the latest SAK and oldest SAK (if
active) within the last two seconds. Because MKPDUs are transmitted
every 2 seconds (MKA_HELLO_TIME), the solution implemented here
calculates lpn based on the txsc->next_pn read during the previous MKPDU
transmit.
Upon receiving and decoding a SAK Use parameter set with delay
protection enabled, the KaY will update the SecY's lpn if the delay
protect lpn is greater than the SecY's current lpn (which is a product
of last PN received and replay protection and window size).

IEEE Std 802.1X-2010, 9.3.1 defines following restrictions for CKN:
"MKA places no restriction on the format of the CKN, save that it comprise
an integral number of octets, between 1 and 32 (inclusive), and that all
potential members of the CA use the same CKN. No further constraints are
placed on the CKNs used with PSKs, ..."
Hence do not require a 32 octet long CKN but instead allow a shorter CKN
to be configured.
This fixes interoperability with some Aruba switches, that do not accept
a 32 octet long CKN (only support shorter ones).

Advertise vendor specific Multi-AP IE in (Re)Association Request frames
and process Multi-AP IE from (Re)Association Response frames if the user
enables Multi-AP fuctionality. If the (Re)Association Response frame
does not contain the Multi-AP IE, disassociate.
This adds a new configuration parameter 'multi_ap_backhaul_sta' to
enable/disable Multi-AP functionality.
Enable 4-address mode after association (if the Association Response
frame contains the Multi-AP IE). Also enable the bridge in that case.
This is necessary because wpa_supplicant only enables the bridge in
wpa_drv_if_add(), which only gets called when an interface is added
through the control interface, not when it is configured from the

After the network changed to a new channel, perform an SA Query with the
AP after a random delay if OCV was negotiated for the association. This

channel of the network. This commit is adding only the station side
functionality for this, i.e., the AP behavior is not changed to
disconnect stations with OCV that do not go through SA Query.

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.

The previous implementation ended up replacing all pending IEs prepared
for Association Request frame with the FT specific IEs (RSNE, MDE, FTE)
when going through FT protocol reassociation with the wpa_supplicant
SME. This resulted in dropping all other IEs that might have been
prepared for the association (e.g., Extended Capabilities, RM Enabled
Capabilities, Supported Operating Classes, vendor specific additions).

appropriate values for FT protocol while maintaining other already
