Apologies, this maintainance service is best effort. I am also going to be very busy until April to complete a few more deliverables, I cannot afford more cancelled projects. I will try to collect what is left for net-next and wait for the next merge window. Therefore, I suggest you start with a much smaller series with a carefully selected subset including preparatory patches. I suggest you start with the software enhancements only. Please, add datapath tests. As for the hardware offload part, I have a board that I received 4.5 ago years as a engineering sample that maybe I can use to test this, but no idea, really. You are a passer-by (ahem, "contributor"), this will get merged upstream at some point and we will have to maintain all this new code without your help maybe ... (people change bussiness units...), I have to understand what is going on here. The throughput available is limited, I am afraid we can only go _slow and careful_. Thanks. P.S: You work is important, very important, but maybe there is no need to Cc so many mailing lists and people, maybe netdev@, netfilter-devel@ and bridge@ is sufficient.
