Abstract
A method, a network adapter, a host system, and a network device for implementing a network adapter offload function. If a data packet received by the network adapter or the host system is a data packet unknown to the network adapter, the data packet unknown to the network adapter is parsed, a new policy entry is generated, and the new policy entry is updated into the host policy table and the network adapter policy table. Therefore, for a packet that includes a new proprietary or standard protocol header Tag, only a functional module that parses the packet needs to be updated, so that the functional module is capable of processing such a packet and delivering a new policy entry to the host policy table and the network adapter policy table and the network adapter does not need to be changed.
