  • determining, according to a network adapter policy table stored in a network adapter or a host policy table stored in a host system, whether a received data packet is known to the network adapter or unknown to the network adapter;

    performing, by the network adapter and according to a policy entry in the network adapter policy table, a corresponding protocol stack offload operation for the data packet known to the network adapter based on the determination that the data packet is known to the network adapter;

    parsing the data packet unknown to the network adapter based on the determination that the data packet is unknown to the network adapter;

    generating a new policy entry based on the determination that the data packet is unknown to the network adapter; and

    updating the new policy entry into the host policy table and the network adapter policy table based on the determination that the data packet is unknown to the network adapter.
