       ib_mad_addr_t * umad_get_mad_addr(void *umad);

DESCRIPTION top

       umad_get_mad_addr() returns a pointer to the ib_mad_addr struct
       within the specified umad buffer.

RETURN VALUE top

       The return value is a pointer to an ib_mad_addr_t struct, as
       specified in <infiniband/umad.h>.

       typedef struct ib_mad_addr {
               uint32_t qpn;
               uint32_t qkey;
               uint16_t lid;
               uint8_t  sl;
               uint8_t  path_bits;
               uint8_t  grh_present;
               uint8_t  gid_index;
               uint8_t  hop_limit;
               uint8_t  traffic_class;
               uint8_t  gid[16];
