Add RDMA_NLDEV_ATTR_RES_SUMMARY_ENTRY_MAX netlink attribute to expose device resource limits (max_qp, max_cq, max_mr, max_pd, max_srq) in the resource summary alongside the existing current count. This allows userspace tools like iproute2's rdma to display resource usage in curr/max format. Expected output from "rdma resource show": Before: 0: mlx5_0: qp 123 cq 45 mr 200 pd 10 After: 0: mlx5_0: qp 123/131072 cq 45/65536 mr 200/1000000 pd 10/32768 In JSON output, both "curr" and "max" fields will be provided so that scripts can compute percentages if needed. The new attribute is optional and backward compatible - old userspace tools will simply ignore it.
