31 * needed for InfiniBand support are described here. These cfgadm
32 * interfaces issue ioctl(s) to the IB nexus driver. Attachment points
33 * supported are - IOC, VPPA, Port, HCA_SVC and Pseudo dynamic ap_ids,
34 * the HCA static ap_id, and the IB static ap_id.
35 *
36 * Given InfiniBand bus is fabric based, #of dynamic ap_ids present are
37 * unknown at any given point of time. Hence this plugin uses a
38 * packed nvlist data structure to hold ap_id related information.
39 * The IB nexus driver allocates the nvlist data in the kernel
40 * and this plugin processes the data (it is freed by IB nexus driver).
