        syssrc/sys/dev/scsipi: atapi_wdc.c

Log Message:
If the data len if not a multiple of 2 bytes, force PIO mode. DMA can't
deal with such xfers, and can wedge the system with some controllers.
It's a bug to request such xfers for ATAPI, but as the request may come
from userland we have to protect against it.
