[Support]: coalescing features about amzn-drivers HOT 5 OPEN

Hi @likewise

Adaptive TX moderation was never supported, only Adaptive RX moderation is supported and is enabled by default in the driver.
Though execution of ethtool may show all of these parameters, you should focus on rx-usecs, tx-usecs and Adaptive RX.
ethtool outputs all the standard information it has, and each driver fills the fields that it supports, though ethtool still outputs all of the fields.

I do see that all of the values are 0 in your case, I assume you've loaded the github driver and have tried manipulating some of the values (Like disabling interrupt moderation, as suggested in our best practices for some use-cases)?

Would you like to share your use-case and what you're trying to achieve?

Use case is quick response time to RX for low traffic, either quick interrupts or no interrupts and busy polling I guess.

Hi @likewise
Please check the best practices page, there's a question about best latency there (Q: What are the optimal settings for achieving the best latency), I believe that the steps there will be helpful.
Let us know otherwise.
