qcacmn: Add a new feature to support tagging of IPv4/v6 flows

Browse Source 
Tags are programmed using wlanconfig commands. Rx IPv4/v6
TCP/UDP packets matching a 5-tuple are tagged using HawkeyeV2 hardware.
Tags are populated in the skb->cb in the REO/exception/monitor data
path and sent to upper stack
