LS1021A AX88179 USB 3.0 Gigabit Ethernet Adapter

Hi,

 

I'm using a USB 3.0 Gigabit Ethernet adapter with a LS1021A reference board. It is an off the shelf adapter based on the AX88179. The board is running the 3.12 kernel built from the Yocto SDK.

When testing with iperf, a few packets are exchanged over the USB adapter Ethernet interface (eth3). Then, it hangs in the middle of the test.

The interface does not respond to pings or arp requests. When I try to ping another IP from the LS1021A shell, there are no packets observed on wireshark. I checked dmesg and I don’t see any error message.

 

Any suggestions on how to solve this? Or how to obtain more logs to get better clarity?

 

Thanks!
