I am verifying the function about pcie to net port on armada-3720 ESPRESSObin. I insert 3 PCIE network cards in 3720 with PCIE bridge, connect to PC by switch. PC ping 3 net port at the same time ,but only one net port could be pinged successfully.
I use the same test environment to test on the cavium's development board ,and PC can ping 3 network cards successfully at the same time.
Besides, I used 3 network cards connect to 3 PC directly not by switch on 3720, and 3 PC can also ping 3 network cards successfully at the same time.
