372 * Send an MCMember Delete query to the SA (eg to leave a multicast
373 * group). The callback function will be called when the query
374 * completes (or fails); status is 0 for a successful response, -EINTR
375 * if the query is canceled, -ETIMEDOUT is the query timed out, or
376 * -EIO if an error occurred sending the query. The resp parameter of
377 * the callback is only valid if status is 0.
378 *
379 * If the return value of ib_sa_mcmember_rec_delete() is negative, it
380 * is an error code. Otherwise it is a query ID that can be used to
381 * cancel the query.
