My understanding of things is that the current AF_XDP patches were going to be updated to have more of a model agnostic API such that they would work for either the "typewriter" mode or the descriptor ring based approach. The current plan was to have the zero copy patches be a follow-on after the vendor agnostic API bits in the descriptors and such had been sorted out. I believe you guys have the descriptor fixes already right? In my opinion the i40e code isn't mature enough yet to really go into anything other than maybe net-next in a couple weeks. We are going to need a while to get adequate testing in order to flush out all the bugs and performance regressions we are likely to see coming out of this change. - Alex
