IB/iser: Limit the max size of a scsi command
Currently, the data length of a command coming down from scsi-ml is limited only by the size of its sg list (sg_tablesize). The max data length may be different for different page size values. By setting max_sectors, we limit the data length to max_sectors*512 bytes. Signed-off-by: Erez Zilber <erezz@voltaire.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
