Zusammenfassung:	Some embodiments of the invention provide a method for offloading one or more data message processing services from a machine executing on a host computer. The method is performed at a virtual network interface card (VNIC) that executes within a set of virtualization software executing on the host computer and that is connected to the machine. The method uses a set of configuration data received from the machine to perform the set of data message processing services for a first set of data messages belonging to a particular data message flow associated with the machine. The method determines that a physical network interface card (PNIC) connected to the host computer is available to perform the set of data message processing services for a subsequent second set of data messages belonging to the particular data message flow. The method directs the PNIC to perform the set of data message processing services for subsequent data messages belonging to the particular data message flow.
