Hi,

I'm getting the following errors in dmesg about every 1s on a D06:

[  766.761823] hns3 0000:bd:00.0: get sfp speed failed -5
[  767.785823] hns3 0000:bd:00.0: get sfp speed failed -5
[  768.809820] hns3 0000:bd:00.0: get sfp speed failed -5
[  769.833818] hns3 0000:bd:00.0: get sfp speed failed -5

Reverting this patch fixes the issue.
