Register the specified management class and version for port

Usage

#include <infiniband/umad.h>

int umad_register(int portid, int mgmt_class, int mgmt_version , uint8_t rmpp_version, long method_mask[16/sizeof(long)]);

Overview

umad_register() registers the specified management class, management version, and whether RMPP is being used for the port specified by the portid parameter. If method_mask array is provided, the caller is registered as a replier (server) for the methods having their corresponding bit on in the method_mask. If method_mask is NULL, the caller is registered as a MAD client, meaning that it can only receive replies on MADs that it sent (solicited MADs).

Return value

umad_register() returns non-negative agent id number on success, and a negative value on error as follows:
-EINVAL invalid port handle
-EPERM registration failed
