What is the tx_restart_queue?

What causes tx_restart_queue to increment?

Is it normal to see packet drops when tx_restart_queue increments?

I have seen incrementing tx_restart_queue as well, but I can't find any good documentation describing exactly what it means. I found this thread from several years ago:

I don't know if the reasoning is still valid. It seems to suggest that you don't have a high enough interrupt rate when sending. Is there anything about your configuration that would affect your interrupt rate?

Intel would provide a useful service to the community if they would document what each statistic shown in ethool -S means!
