3CR990 NICS

NIC Overview	The 3CR990 network interface cards (NICs) represent a new generation of secure,
	intelligent client NICs with an on-board RISC processor (3XP processor). The RISC
	processor is designed to optimize system and network performance. Optimization
	occurs by offloading key networking and security tasks even when running
	bandwidth-intensive applications such as voice, video, imaging, and Internet and
	intranet applications. These NICs connect your PCI-compliant PC to a 10 Mbps or
	100 Mbps Ethernet network and provide advanced features for high performance
	and secure transactions.
	The 3CR990 NICs provide up to 3DES (Data Encryption Standard 168-bit)
	encryption. Encryption processing is handled entirely by the RISC processor
	and the encryption chip that reside on the 3CR990 NICs.
	The onboard encryption chip enables true end-to-end network security (IPSec)
	at the data capacity of the connected network cable (wire speed), without
	sacrificing performance.
