imx6UL ethernet switching performance

Hello,

 

Does i.MX6 Ultralite support any kind of hardware acceleration of Ethernet switching on its two Ethernet interfaces? And if yes how to enable it?

 

If I compile and use the Linux Ethernet bridge module, then system load at maximum 100Mbit throughput is approximately 50% when 1500 byte packets are used. If smaller packets are used then the system load goes easily to 100%.

 

Platform used: IMX6UL-EVK

Part: PCIMX6G2CVM05AA

Kernel/BSP: Linux imx6ulevk 3.14.38-6UL_ga+ge4944a5 (compiled with bridge module)

Traffic generator: iperf -s / iperf -c

Load test: sar -u 5 100

 

Thank you very much beforehand.

 

Vladislav
