Subject: qcacld-3.0: Cache ARP/NS offload request at wma layer

qcacld-2.0 to qcacld-3.0 propagation

As Current WMI interface need both the ARP/NS configuration
in single command. To support active offload host need to
cache the ARP/NS at wma layer so host can fill the other
request and configure down to firmware complete request
(ARP+NS).
