[ofw] typical values for ci_umv_buf_t

>In that case there's no IOCTL, though, right?

The comments in ib_uvp.h indicated that verb related calls were broken into 3
steps: pre call, IOCTL, and post call.  Are you saying that that isn't always
the case?  The few places I checked in IBAL, the code did:

status = pre()
if (status != IB_SUCCESS)
	return status;

IOCTL

...

Does IBAL use multiple status values to indicates success?
