   4 Subject: [PATCH] mesh: properly handle sae_password
   5
   6 The recently introduced sae_password parameter is only handled properly
   7 in wpa_supplicant/sme.c while wpa_supplicant/mesh.c assumed that
   8 ssid->passphrase exclusively holds the secret.
   9 Import the logic from sme.c to mesh.c to allow having only sae_password
  10 set which otherwise throws this error:
  11 AP-ENABLED
  12 mesh: Passphrase for SAE not configured
  13 Init RSN failed. Deinit mesh...
  14 wlan1: interface state ENABLED->DISABLED
  15 AP-DISABLED
  16 Segmentation fault
