From 42e9a92fe6a9095bd68a379aaec7ad2be0337f7a Mon Sep 17 00:00:00 2001 From: Robert Love Date: Tue, 9 Dec 2008 15:10:17 -0800 Subject: [SCSI] libfc: A modular Fibre Channel library libFC is composed of 4 blocks supported by an exchange manager and a framing library. The upper 4 layers are fc_lport, fc_disc, fc_rport and fc_fcp. A LLD that uses libfc could choose to either use libfc's block, or using the transport template defined in libfc.h, override one or more blocks with its own implementation. The EM (Exchange Manager) manages exhcanges/sequences for all commands- ELS, CT and FCP. The framing library frames ELS and CT commands. The fc_lport block manages the library's representation of the host's FC enabled ports. The fc_disc block manages discovery of targets as well as handling changes that occur in the FC fabric (via. RSCN events). The fc_rport block manages the library's representation of other entities in the FC fabric. Currently the library uses this block for targets, its peer when in point-to-point mode and the directory server, but can be extended for other entities if needed. The fc_fcp block interacts with the scsi-ml and handles all I/O.
