This call blocks until the multicast identifier is destroyed. It may not be called from within the multicast callback; however, returning a non- zero value from the callback will result in destroying the multicast tracking structure.

ib_sa_join_multicast - Initiates a join request to the specified multicast group. : SA client : Device associated with the multicast group. : Port on the specified device to associate with the multicast group. : SA multicast member record specifying group attributes. : Component mask indicating which group attributes of rec are valid. : GFP mask for memory allocations. : User callback invoked once the join operation completes. : User specified context stored with the ib_sa_multicast structure.
This call initiates a multicast join request with the SA for the specified multicast group. If the join operation is started successfully, it returns an ib_sa_multicast structure that is used to track the multicast operation. Users must free this structure by calling ib_free_multicast, even if the join operation later fails. (The callback status is non-zero.)
If the join operation fails; status will be non-zero, with the following failures possible: -ETIMEDOUT: The request timed out. -EIO: An error occurred sending the query. -EINVAL: The MCMemberRecord values differed from the existing group's. -ENETRESET: Indicates that an fatal error has occurred on the multicast group, and the user must rejoin the group to continue using it.

Send a Path Record Get query to the SA to look up a path. The callback function will be called when the query completes (or fails); status is 0 for a successful response, -EINTR if the query is canceled, -ETIMEDOUT is the query timed out, or -EIO if an error occurred sending the query. The resp parameter of the callback is only valid if status is 0.
If the return value of ib_sa_path_rec_get() is negative, it is an error code. Otherwise it is a query ID that can be used to cancel the query.
