sys/cam cam_xpt.c
Log:
Correct an off by one in the calculation of the "full inquiry length".
Although the SCSI spec indicates that the "additional length field" of
the inquiry data is "n - 4", n is an index to the last byte of inquiry
data, not the length of data. For length calculations, use 5, not 4.
In xpt_set_transfer_settings, never attempt U320 transfer speeds if
the information transfer units capability is not supported by the device.
The SPI4 spec precludes running any PACED transfer speed without IUTs.
