scsi: target: iscsi: cxgbit: fix max iso npdu calculation
[ Upstream commit
1b350ea0c2f4df9aa30426614c8eb755a8c32814 ]
- rounddown CXGBIT_MAX_ISO_PAYLOAD by csk->emss before calculating
max_iso_npdu to get max TCP payload in multiple of mss.
- call cxgbit_set_digest() before cxgbit_set_iso_npdu() to set
csk->submode, it is used in calculating number of iso pdus.
