<p class="Pp">The <code class="Nm">bhnd</code> driver provides a unified kernel
    bus interface to the on-chip interconnects used in Broadcom Home Networking
    Division (HND) devices.</p>
<p class="Pp">The Broadcom HND device family consists of SoCs (System On a Chip)
    and host-connected chipsets based on a common library of Broadcom IP cores
    connected via an internal hardware bus architecture. Drivers for these cores
    are implemented against the unified <code class="Nm">bhnd</code>
  interface.</p>
<p class="Pp">The Sonic Inc. Silicon Backplane used in earlier HND devices is
    supported by the <a class="Xr">siba(4)</a> BHND driver.</p>
<p class="Pp">The ARM AMBA-based interconnect used in later HND devices is
    supported by the <a class="Xr">bcma(4)</a> BHND driver.</p>
