Abstract
Some embodiments provide a method for performing data message processing at a smart NIC of a computer that executes a software forwarding element (SFE). The method stores (i) a set of cache entries that the smart NIC uses to process a set of received data messages without providing the data messages to the SFE and (ii) rule updates used by the smart NIC to validate the cache entries. After a period of time, the method determines that the rule updates are incorporated into a data message processing structure of the SFE. Upon incorporating the rule updates, the method deletes from the smart NIC (i) the rule updates and (ii) at least a subset of the cache entries.
