From ad757cdfd2a40c9d5310d00f24427525788341cd Mon Sep 17 00:00:00 2001 From: Andreas Herrmann Date: Fri, 13 Jan 2006 02:26:11 +0100 Subject: [PATCH] [SCSI] zfcp: transport class adaptations II Replaced zfcp adapter attributes with fc_host attributes: fc_topology by port_type, physical_wwpn by permanent_port_name. Make use of fc_host attribute supported_speeds. Removed zfcp adapter attribute physical_s_id.
