So I’ve been experimenting with ethtool to configure certain offload settings for my lan ports. Obviously I am tuning for lower latency and less packet segmentation. I was curious enough to fiddle around with coalesce settings for my lan port which is eth0 and it uses an embedded driver which is different from my eth2 and eth1 which both can be configured as lan or wan depending on which port you use for wan. Well my curiosity began when I noticed that you can configure eth0 coalesce parameters but for some reason you cannot access these parameters for eth2 or eth1. When you do type in for example “ethtool -c eth2”, it will give you the response “cannot get coalesce settings”. Just for my own experimentation. Does anyone know how to actually bypass and enter into these nic settings? If anyone has any insight I’d greatly appreciate it. And by the way my eth2 and eth1 ports use the kmod-r8125-rss driver and my router is the NanoPi R6S
Please post outputs of
ubus call system board
ethtool -i eth2
Not all featires are coonfigurable in every driver.
