When this attribute is true, the STA shall indicate at the MAC service interface received MSDUs regardless of the setting of the WEP subfield of the Frame Control field, so long as no other VLAN parameters necessitate use of encryption. The default value of this attribute shall be true. The general use for awcVlanAllowEncrypted to be true even when no static WEP keys are set for a VLAN is to allow a station to utilize EAP authentication to encrypt directed packets, even while multicast packets are unencrypted.
