Ethernet Network Switch

Many devices supported by OpenWrt contain an Ethernet network switch. Most switches are configurable and divers options are available. We require two software components:

  1. a kind of a driver
  2. a utility

Ethernet Network Switch models

Realtek

Qualcomm / Atheros

Note: Atheros Switch-Chips with the 'N' designation include the Hardware NAT function.

Broadcom

MediaTek / Ralink

Other

  • IC+ IP17xx

Drivers

Utility

Features

  • some Switches contain a functionality called "Hardware NAT"; support for this features has not yet been included into OpenWrt. Since the CPUs used in CPE Routers are relatively slow, expect 2 to 4 times performance gain if you were to use Hardware NAT, e.g. without hardware NAT some router could achieve 400Mbit/s at full CPU load, with hardware NAT it could achieve 900Mbit/s at full CPU load. OpenWrt developer is supposed to have said, that implementing HW-NAT support would be unacceptably hacky to accomplish.
