This is the second in a set of patch series to add in TID RDMA. This series
is the patches to support OPFN which is the feature negotiation protocol used
by TID RDMA. This is totally hidden from users and does not impact any API. It
done under the hood at the driver level.
At a high level OPFN enables exchanging parameters between two hosts using
IB compare and swap requests to a special virtual address. The request uses
a reserved IB work request opcode (see patch 3).
