Has anyone ported lan7430?
I ported lan7430 to jetson tx2 for using dual ethernet port
everything is okay but lan7430 port occurs multicast udp packets loss when receiving.

please give me advice on how to prevent packet loss.

my jetson tx2 kernel version is 4.9.140-tegra

thank you for your help

Hi gpgjffpgg,

We haven’t test the lan7430, thus can’t give the answer where might be the issue. but you can try the jetson_clocks.sh script to maximize Jetson TX2 performance by setting the static maximum frequencies of the CPU, GPU and EMC clocks to see the situation can be improved.

Thanks

Hi, I am in a similar situation where I need extra ethernet ports on the Jetson Xavier NX, and Im also using LAN7430 in my design. Do you mind to share how to port the driver from the newer linux kernel to 4.9 Tegra?

Thanks!
