Tyrel,
The fcp_rsp_info structure as defined in the FC spec has an initial 3 bytes
reserved field. The ibmvfc driver mistakenly defined this field as 4 bytes
resulting in the rsp_code field being defined in what should be the start of
the second reserved field and thus always being reported as zero by the
driver.
Applied to 4.16/scsi-fixes, thanks!
