The new set of API replace the PacketKeepalive system API which is only specific for IPsec NAT-T keepalive packet. Allows applications to request different types of keepalives through the same set of API. By using keepalives, applications could request system to periodically send specific packets on their behalf, using hardware offload to save battery power. This change would only address interface change and test part of original functionality. After all reference of PacketKeepalive are removed, another change would be submitted to remove old API.
