Plugable USB-C to 2.5G Ethernet Adapter (USBC-E2500)
This is what matters about Plugable USB-C to 2.5G Ethernet Adapter (USBC-E2500).
About
A bus-powered 2.5Gbps Ethernet adapter built on the Realtek RTL8156B, using the CDC-NCM driver model so packet framing offloads to the chip instead of burning host CPU cycles — important on thermally-constrained handhelds. iPerf testing hits 2.37Gbps sustained. macOS lacks Jumbo Frame support (1500 MTU only); Linux needs kernel 5.0+ for full functionality.
Ports: 1× Ethernet (2.5GBASE-T) and 1× USB-C (host, includes USB-A adapter)
