370 | * multicast group. If the join operation is started successfully, it returns | |
371 | * an ib_sa_multicast structure that is used to track the multicast operation. | |
372 | * Users must free this structure by calling ib_free_multicast, even if the | |
373 | * join operation later fails. (The callback status is non-zero.) | |

378 | * -EIO: An error occurred sending the query. | |
379 | * -EINVAL: The MCMemberRecord values differed from the existing group's. | |
380 | * -ENETRESET: Indicates that an fatal error has occurred on the multicast | |
381 | * group, and the user must rejoin the group to continue using it. | |
