+- Receiver Side Scaling（RSS）
+- RSS supports IPv4, IPv6, TCPv4, TCPv6, UDPv4 and UDPv6, use inner type for VXLAN as default
+- MAC/VLAN filtering
+- Checksum offload
+- TSO offload
+- LRO offload
+- Promiscuous mode
+- Port hardware statistics
+- Link state information
+- Link flow control(pause frame)
+- Scattered and gather for TX and RX
+- SR-IOV - Partially supported VFIO only
+- VLAN filter and VLAN offload
+- Allmulticast mode
+- MTU update
+- Unicast MAC filter
+- Multicast MAC filter
+- Set Link down or up
+- FW version
+- Multi arch support: x86_64, ARMv8.
+
+Prerequisites
+-------------
