NAME
rdma_notify - Notifies the librdmacm of an asynchronous event.
SYNOPSIS
#include <rdma/rdma_cma.h>
int rdma_notify (struct rdma_cm_id *id, enum ibv_event_type event);
ARGUMENTS
id RDMA identifier.
event Asynchronous event.
DESCRIPTION
Used to notify the librdmacm of asynchronous events that have occurred
on a QP associated with the rdma_cm_id.
RETURN VALUE
Returns 0 on success, or -1 on error. If an error occurs, errno will
be set to indicate the failure reason. If errno is set to EISCONN
(transport endpoint is already connected), this indicates that the the
underlying communication manager established the connection before the
call to rdma_notify could be processed. In this case, the error may
safely be ignored.

NOTES
Asynchronous events that occur on a QP are reported through the user's
device event handler. This routine is used to notify the librdmacm of
communication events. In most cases, use of this routine is not neces-
sary, however if connection establishment is done out of band (such as
done through Infiniband), it's possible to receive data on a QP that is
not yet considered connected. This routine forces the connection into
an established state in this case in order to handle the rare situation
where the connection never forms on its own. Calling this routine
ensures the delivery of the RDMA_CM_EVENT_ESTABLISHED event to the
application. Events that should be reported to the CM are:
IB_EVENT_COMM_EST.
