I'v got a board with five ethernet port, AR9331 as CPU.

but when I execute 'make menuconfig' ,it seems have no other board to choose which supports four LAN port.

such like WR740Nv5, it doese have five wired ports, but I can't find it in openwrt.(actually, it only have v1 and v3, no v5.)

how could I generate an firmware which support 4LAN+1WAN ?

any help or advice will be appreciated..thanks alot!!

had I described myself clear? I'm not quiet good at English....

anyone know how to figure this out?

AR9331 have only two real ports. One of them have integrated 4 port switch( +1 port for CPU).

How to use the switch ?

here is one example how dmesg indicate the switch.

eth0: Atheros AG71xx at 0xb9000000, irq 4, mode:MII
ag71xx ag71xx.0 eth0: connected to PHY at ag71xx-mdio.1:04 [uid=004dd041, driver=Generic PHY]
eth1: Atheros AG71xx at 0xba000000, irq 5, mode:GMII
eth1: Found an AR7240/AR9330 built-in switch

all 4 ports working like one eth1. if you plan use every port separately you need to create vlans and configure switch port to own vlan. By default all ports in VLAN0 (or VLAN1 depend on OpenWRT version). http://wiki.openwrt.org/doc/uci/network/switch

I can't find this information in mine
