            Select this option to use MbedTLS crypto API's which utilize hardware acceleration.

    config WPA_TLS_V12
        bool "Enable TLS v1.2"

            Select this to enable TLS v1.2 for WPA2-Enterprise Authentication.

    config WPA_WPS_WARS
        bool "Add WPS Inter operatability Fixes"
        default n
        help
            Select this option to enable WPS related IOT fixes with
            different APs. This option fixes IOT related issues with
            APs which do not follow some of the standards of WPS-2.0
            specification. These do not include any of the security
            related bypassing, just simple configuration corrections.

            Current fixes under this flag.
            1. Allow NULL-padded WPS attributes: Some APs keep NULL-padding
            at the end of some variable length WPS Attributes.
            This is not as par the WPS2.0 specs, but to avoid interop issues,
            ignore the padding by reducing the attribute length by 1.
            2. Bypass WPS-Config method validation: Some APs set display/pbc
            button bit without setting virtual/physical display/button bit which
            will cause M2 validation fail, bypassing WPS-Config method validation.
