in case of client roaming a new global entry is added while a corresponding local one is still present. In this case the node can safely pass the WIFI flag from the local to the global entry. This change is required to let the AP-isolation correctly working in case of roaming: if a generic WIFI client C roams from node A to B, A adds a global entry for C without adding any WIFI flag. The latter will be set only later, once A has received C's advertisement from B. In this time period the AP-Isolation (if enabled) would not correctly work since C is not marked as WIFI, so allowing it to communicate with other WIFI clients.
