Subject: [PATCH] WIFI-13428 Fix:Traffic Disruption for MPSK clients for
yuncore_fap655
Fix Traffic Disruption for MPSK clients for yuncore_fap655 when
vlan-id of the lan port is modified.Any change in swconfig resets the
internal switch of FAP655 due to which all the dynamically added vlans
for MPSK clients are lost. Configure the Dynamic Vlans for MPSK Clients
again after switch reset.
