help
Enable Espressif's roaming app to allow for efficient Wi-Fi roaming.
This includes configurable periodic environment scans, maintaining a cache of the
best APs, handling low rssi events etc.
802.11k/v is selected so roaming-app scans can deliver beacon/probe frames to
the supplicant BSS table used by candidate_security_match() for RSN IE checks.
Without it, PMF/SAE-PK/H2E validation can fall back to coarse authmode heuristics.
Risk Warning
Please note that this feature is still experimental and enabling this potentially can
lead to unpredictable scanning, connection and roaming attempts.
