204 Capability that is set by the target driver to inform the \fBHBA\fR of the
205 granularity, in bytes, of the \fBDMA\fR breakup. The \fBHBA\fR \fBDMA\fR limit
206 structure is set to reflect the byte total of this setting. See
207 \fBddi_dma_lim_sparc\fR(9S) or \fBddi_dma_lim_x86\fR(9S). The \fBsector-size\fR
208 should be set to the size of the physical disk sector. The capability defaults
209 to 512 bytes.
