From a7b12a279faaad26837276065104a1f9cf60e962 Mon Sep 17 00:00:00 2001 From: Joe Eykholt Date: Tue, 20 Jul 2010 15:20:08 -0700 Subject: [SCSI] libfc: add FLOGI state to rport for VN2VN The FIP proposal for VN_port to VN_port point-to-multipoint operation requires a FLOGI be sent to each remote port. The FLOGI is sent with the assigned S_ID and D_IDs of the local and remote ports. This and the response get FIP-encapsulated for Ethernet. Add FLOGI state to the remote port state machine. This will be skipped if not in point-to-multipoint mode. To reduce a little duplication between PLOGI and FLOGI response handling, added fc_rport_login_complete(), which handles the parameters for the rdata struct.
