RDMA/core: Add support to dump SRQ resource in RAW format
Add support to dump SRQ resource in raw format. It enable drivers to return the entire device specific SRQ context without setting each field separately. Example: $ rdma res show srq -r dev hns3 149000... $ rdma res show srq -j -r [{"ifindex":0,"ifname":"hns3","data":[149,0,0,...]}] Signed-off-by: wenglianfa <wenglianfa@huawei.com> Link: https://lore.kernel.org/r/20230918131110.3987498-3-huangjunxian6@hisilicon.com Signed-off-by: Leon Romanovsky <leon@kernel.org>
