Traffic Control Offload
Use traffic control (TC) offload in the 45000 Series Adapters to control flows
based on packet attributes (primarily on the receive side) and to choose different
traffic classes (for example, Multiqueue Priority Qdisc [MQPRIO] offload) on the
adapter based on flow priorities on the transmission side.
This chapter provides the following information about traffic control offload:

 The latest OSs, including SLES 12 SP3 and Ubuntu
 (Optional) The latest TC or IP utility (recommended if you encounter
problems with inbox utilities)
Current Support
The traffic control offload feature currently supports the following:
 Ingress packet redirection based on the destination IP in the packet to the
offloaded MAC-vLAN devices or SR-IOV virtual functions (VFs). See
