I have enabled flow offloading for MT7621 on my ZBT WE-1326. I have few questions.
1- I see that iptables had a rule with FLOWOFFLOAD and it seems to be doing something.
61210 3763K FLOWOFFLOAD all -- any any anywhere anywhere /* !fw3: Traffic offloading */ ctstate RELATED,ESTABLISHED FLOWOFFLOAD hw
Is there any other way of checking that it does do anything? Other than using a benchmark? Some way to see that hardware is actually doing some work?
2- There are 2 checkboxes on LUCI. It says Software flow offloading
and Hardware flow offloading
. OK I understand the hardware offloading uses some CPU features. But what does Software flow offloading
do exactly? I mean, isn't it done in software anyway even when it is not selected? What is the difference between software offloading and no offloading?
Thanks!
