 * switch has one of its ports connected to an SFP (Small Form
 * Factor pluggable) optical fiber receiver, which is bridged
 * to the twisted pair connector LAN1.
 *
 * This device tree is inspired by research from the OpenWrt

 * NPeca75, mrhaav and csom.

 * Some devices have a USB type A host receptacle mounted,
 * some do not.
