[SCSI] iscsi: rename DEFAULT_MAX_RECV_DATA_SEGMENT_LENGTH
This patch renames DEFAULT_MAX_RECV_DATA_SEGMENT_LENGTH to avoid confusion with the drivers default values (DEFAULT_MAX_RECV_DATA_SEGMENT_LENGTH is the iscsi RFC specific default). Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
