It isn't really relevant whether current implementations behave this way
- the old devices never seem to completely go away.

Subject: FCP-4: FCP_RSP IU Note
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
