摘要： Virtual network interfaces receive data from distinct subsets of receive rings of a network interface card. In other words, each virtual network interface “owns” its own subset of receive rings of the network interface card. The assignment of virtual network interfaces to particular receive rings of the network interface cards may be determined, for example, dynamically, based on priorities associated with particular virtual network interfaces, based on function type, and/or based on service need.
摘要翻译： 虚拟网络接口从网络接口卡的接收环的不同子集接收数据。 换句话说，每个虚拟网络接口“拥有”自己的网络接口卡的接收环子集。 可以基于功能类型和/或基于服务需要，基于与特定虚拟网络接口相关联的优先级来动态地确定虚拟网络接口到网络接口卡的特定接收环的分配。

摘要： Encrypted data packets are received by a network interface card. The network interface card, upon determining that the received data packets are encrypted, directs the encrypted data packets to decryption hardware in the network interface card. The decryption hardware decrypts the encrypted data packets and forwards the decrypted data packets to a hardware classifier that classifies the decrypted data packets and directs the classified decrypted data packets to the appropriate receive resource(s) of the network interface card.
