From 7b2787ec15b9d1c2f716da61b0eec21a3f5e6520 Mon Sep 17 00:00:00 2001 From: Robert Love Date: Fri, 7 May 2010 15:18:41 -0700 Subject: [SCSI] libfc: Move the port_id into lport This patch creates a port_id member in struct fc_lport. This allows libfc to just deal with fc_lport instances instead of calling into the fc_host to get the port_id. This change helps in only using symbols necessary for operation from the libfc structures. libfc still needs to change the fc_host_port_id() if the port_id changes so the presentation layer (scsi_transport_fc) can provide the user with the correct value, but libfc shouldn't rely on the presentation layer for operational values.
