Ok, are these implementations compliant with FCP-4 ?

FCP-4 still has the following note:
NOTE 7 - Some early implementations presented the FCP_RSP IU without the
FCP_RESID field, FCP_SNS_LEN field, and FCP_RSP_LEN field if the
FCP_RESID_UNDER bit, FCP_RESID_OVER bit, FCP_SNS_LEN_VALID bit, and
FCP_RSP_LEN_VALID bit were all set to zero. This non-standard behavior should
be tolerated.
Are there still implementations that present the FCP_RSP IU without the
FCP_RESID field, FCP_SNS_LEN field, and FCP_RSP_LEN field if the
FCP_RESID_UNDER bit, FCP_RESID_OVER bit, FCP_SNS_LEN_VALID bit, and
FCP_RSP_LEN_VALID bit were all set to zero ?
I would really hope that we have moved past this non-standard behavior and
would like to remove this note.
Thanks...Dave
Yes, there are implementations still out there deployed that still have this
behavior.
