The ethernet ports on the AVM FRITZRepeater 3000 are not separated
between LAN and WAN in the stock firmware. OpenWrt currently abstracts
port 4 as eth0 and port 5 as eth1, bridging them in the kernel.
This patch adjusts the GMAC port bitmasks and default bitmask for ar40xx
to bridge them on the switch, avoiding traffic on both ports to pass
thru the CPU.
