From: Chris Leech Date: Tue, 25 Aug 2009 20:59:35 +0000 (-0700) Subject: [SCSI] fcoe: move netdev to fcoe_interface X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=250249898a92a1228050f40fbe3c05deb1392da8;p=linux-beck.git [SCSI] fcoe: move netdev to fcoe_interface The network interface needs to be shared between all NPIV VN_Ports, therefor it should be tracked in the fcoe_interface and not for each SCSI host in fcoe_port.
