In SPC-4 paragraph 4.22.4 I found that the T10-PI guard is the CRC
computed from the generator polynomial x^16 + x^15 + x^11 + x^9 + x^8
+ x^7 + x^5 + x^4 + x^2 + x + 1. Could you tell me where I can find
which guard computation method IB_T10DIF_CSUM corresponds to ?
Bart.
The IB_T10DIF_CSUM computation method corresponds to IP checksum rules.
this is aligned with SHOST_DIX_GUARD_IP guard type.
Sagi.
