Hi,dann,

Thanks for your test and report.

This patch needs to match new fireware verison ,
And  it  does some work to  be Compatible with older versions.

Can you show me more information？
can you  use "ethtool -i ethx" to get the fireware version ,
and shows me  some other message about hns3?

Thanks
