* NOTE: mbedTLS-3.x release has removed support for RC4 cipher-suite.
* TODO: IDF-4983
*
* Following option is kept as there are a few places in the
* WPA supplicant component in ESP-IDF that relies on this config.
* This shall be removed once the RC4 cipher-suite support is cleanly
* removed from WPA supplicant component.
