Documented selection limits

Match the exact host interface, peripheral/device protocol, connector, firmware, OS/driver and power requirements before ordering. Published maximum rates are interface limits, not guaranteed application throughput. No universal device or current/future OS compatibility is implied. Match USB host generation and OS/driver support; USB bus bandwidth may limit Ethernet line-rate performance. Fiber/SFP variants require the correct transceiver/link partner, supplied modules must be checked. RJ45 Ethernet does not imply PoE output.
