support
Standard
Receive Side Scaling Multiple Rx queues enable the efficient
distribution of network receive processing
across multiple CPUs in multiprocessor
systems
Direct Cache Access (DCA) The I/O device activates a pre-fetch en-
gine in the CPU that loads the data into
the CPU cache ahead of time, before use,
eliminating cache misses and reducing
CPU load

Adapter fault tolerance (AFT)
Switch fault tolerance (SFT)
Adaptive load balancing (ALB)
Teaming support
