[SCSI] be2iscsi: Fix SGL Initilization and posting Pages for Dual Chute
Initialization of SGL and related PAGE posting is to be done for the chute. Based on configuration value of each Chute,SGL initialization and page posting is done. For BE-X family iSCSI protocol is loaded only on single chute Signed-off-by: John Soni Jose <sony.john-n@emulex.com> Signed-off-by: Jayamohan Kallickal <jayamohan.kallickal@emulex.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
