Abstract
Embodiments of the present disclosure relate to determining modification bounds that identify portions of a packet that are safe to modify so that modified portions of the packet may be flushed from a cache to a memory of a network interface card (NIC) of a host system when the entire packet is synchronized from the NIC. A modification bound of the filter may be determined, and a network packet may be received from the NIC. In response to determining that the network packet is to be modified, a portion of the network packet that is safe to modify may be identified based on the modification bound of the filter and modifications may be made thereto. The modified portion of the network packet may be synchronized to the NIC.
