The LLDD provides the unique identifiers (wwpn,wwn) of the port, it's FC address (port_id), and the FC4 roles that are active for the port. For ports that are FCP targets (aka scsi targets), the FC transport maintains consistent target id bindings on behalf of the LLDD. A consistent target id binding is an assignment of a target id to a remote port identifier, which persists while the scsi host is attached. The remote port can disappear, then later reappear, and it's target id assignment remains the same. This allows for shifts in FC addressing (if binding by wwpn or wwnn) with no apparent changes to the scsi subsystem which is based on scsi host number and target id values. Bindings are only valid during the attachment of the scsi host. If the host detaches, then later re-attaches, target id bindings may change. This routine is responsible for returning a remote port structure. The routine will search the list of remote ports it maintains internally on behalf of consistent target id mappings. If found, the remote port structure will be reused. Otherwise, a new remote port structure will be allocated. Whenever a remote port is allocated, a new fc_remote_port class device is created.

Note: Although a port may no longer be part of the topology, it may persist in the remote ports displayed by the fc_host. We do this under 2 conditions: 1) If the port was a scsi target, we delay its deletion by "blocking" it. This allows the port to temporarily disappear, then reappear without disrupting the SCSI device tree attached to it. During the "blocked" period the port will still exist. 2) If the port was a scsi target and disappears for longer than we expect, we'll delete the port and the tear down the SCSI device tree attached to it. However, we want to semi-persist the target id assigned to that port if it eventually does exist. The port structure will remain (although with minimal information) so that the target id bindings also remain. If the remote port is not an FCP Target, it will be fully torn down and deallocated, including the fc_remote_port class device. If the remote port is an FCP Target, the port will be placed in a temporary blocked state. From the LLDD's perspective, the rport no longer exists. From the SCSI midlayer's perspective, the SCSI target exists, but all sdevs on it are blocked from further I/O. The following is then expected. If the remote port does not return (signaled by a LLDD call to fc_remote_port_add()) within the dev_loss_tmo timeout, then the scsi target is removed - killing all outstanding i/o and removing the scsi devices attached to it. The port structure will be marked Not Present and be partially cleared, leaving only enough information to recognize the remote port relative to the scsi target id binding if it later appears. The port will remain as long as there is a valid binding (e.g. until the user changes the binding type or unloads the scsi host with the binding). If the remote port returns within the dev_loss_tmo value (and matches according to the target id binding type), the port structure will be reused. If it is no longer a SCSI target, the target will be torn down. If it continues to be a SCSI target, then the target will be unblocked (allowing i/o to be resumed), and a scan will be activated to ensure that all luns are detected.
