   4 Subject: [PATCH] wpa_supplicant: multi_ap: only enable 4addr mode if not
   5  already enabled
   6 MIME-Version: 1.0
   7 Content-Type: text/plain; charset=UTF-8
   8 Content-Transfer-Encoding: 8bit

  10 If 4addr mode is already enabled, the call to enable it a second time
  11 may fail. If this happens when roaming, it leads to deauthentication.
