umad_register_oui - Man Page

register the specified class in vendor range 2 for port


#include <infiniband/umad.h>

int umad_register_oui(int portid, int mgmt_class, uint8_t rmpp_version, uint8_t oui[3], uint32_t method_mask[4]);


umad_register_oui() registers the specified class in vendor range 2, the specified oui, and whether RMPP is being used for the port specified by the portid handle. 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 or class is not in the vendor class 2 range
-EPERM  registration failed
