+ RDMA and netdev folks
Sorry, to be late in the game, I don't see other patches, but from
the description below it seems like you are reinventing RDMA verbs
model. I have hard time to see the differences in the proposed
framework to already implemented in drivers/infiniband/* for the kernel
space and for the https://github.com/linux-rdma/rdma-core/ for the user
space parts.
Hard NAK from RDMA side.
Thanks
