From 7f74549ff630ad444b0b6bbcabf426f781910906 Mon Sep 17 00:00:00 2001 From: Joe Eykholt Date: Wed, 29 Jul 2009 17:04:12 -0700 Subject: [PATCH] [SCSI] libfc: change debug messages to give host number. libfc debug messages currently show 'lport: :' wher is the hex assigned port-id. When the lport is logged off, that will be zero, so its hard to distinguish which instance is involved. The FC-ID can change if the port is re-patched or changes VSANs. Two lports may even have the same FC-ID if connected to isolated SANs. Change the debug messages to print the SCSI host number "hostN:", which will not change for the life of the lport. Still show the FC_ID on lport messages. Also, add a macro to FC_RPORT_ID_DBG for rport debugging where there's no rdata structure involved. It takes the lport and port_id as parameters. Use this in fc_rport_recv_plogi_req() and fc_rport_recv_logo_req().
