1. A system, comprising a networking device, including:
a network interface to receive network packets having headers including datagram transport layer security (DTLS) headers from a remote device over a packet data network;
packet processing circuitry to:
identify first packets of the received packets for DTLS processing in the packet processing circuitry;
identify second packets of the received packets to bypass DTLS processing in the packet processing circuitry and to be provided to software to perform DTLS processing on the second packets; and
perform DTLS processing on the first packets; and
a host interface to:
provide the DTLS processed first packets to the software; and
provide the second packets to the software to perform DTLS processing on the second packets.
