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.
