Note that this is software offload, not hardware. Device is a Netgear R7800. The ethernet on it is totally broken TBH. But I've also seen this on a Turris Omnia. My question is not really how to fix it. I already know that. I just got the feeling that bypassing parts of the linux network stack would result in less buffering. > On Fri, Aug 10, 2018 at 4:12 PM Rosen Penev wrote: > > > > OpenWrt has backported Netfilter's flow offload functionality from > > kernel 4.17 to 4.14.
