> so it's like rdma, but without using kernel rdma stack?
No sockets here, just transformation rules. It's like offloading
a complex TC rule to hardware version of that transformation.
Yes, there is state, but I argue that it is no different than TC
offloading rules. What if TC had "hash" and "crypt" operations
and we attached them to appropriate u32 matches? You wouldn't
be able to tell the difference.
I think you are way over-obsessed with this FPGA offload thing,
quite frankly.
