The virtual address that is provided by the guest in post_send and post_recv operations is related to the guest address space. This address space is unknown to the HCA resides on host so extra step in these operations is needed to adjust the address to host virtual address. This step, which is done in data-path affects performances. An enhanced verion of MR registration introduced here https://patchwork.kernel.org/patch/11044467/ can be used so that the guest virtual address space for this MR is known to the HCA in host. This will save the data-path adjustment.
