Many devices supported by OpenWrt contain an Ethernet network switch. Most switches are configurable and divers options are available. We require two software components:
- a kind of a driver
- a utility
- AR8216 FastEthernet
- AR8228 + AR8229 FastEthernet: 7-Ports, 5x 100BASE-TX-PHYs
- AR8236 FastEthernet: 6-Ports, 5 x 100BASE-TX-PHYs
- AR8327 + AR8327N GigabitEthernet: 7Ports, 5x 1000Base-T-PHYs
- AR8328 + AR8328N GigabitEthernet: 7Ports, 5x 1000Base-T-PHYs
- Atheros AR7240 built-in switch
- Atheros AR934X built-in switch
Note: Atheros Switch-Chips with the 'N' designation include the Hardware NAT function.
- Broadcom BCM5325
- IC+ IP17xx
- 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.
