From: Mohammed Shafi Shajakhan <moham...@qca.qualcomm.com>
currently the code supports WoW triggers due to
*magic packet
*user defined patterns
*deauth and disassoc patterns
*disconnect - beacon miss, last beacon received timeout,
no ack for keeep alive frames.
we need to support other WoW offload features in the
near future. also a minor cleanup.
