[Commotion-dev] Poor routed throughput eth1 -> eth0 on Bufallo NFiniti?

[Daniel Bryg]

Hey Ben, I redid the test with the A2 F0B model from last year's code
sprint, fresh trunk, and got speeds around 100Mbit/s with scp:
128M.bin     | 131072 kB | 11915 kB/s

There's nothing special in the iptables other than masquerading and this
is my network config:

cat /etc/config/network

config 'interface' 'loopback'
        option 'ifname' 'lo'
        option 'proto' 'static'
        option 'ipaddr' '127.0.0.1'
        option 'netmask' '255.0.0.0'

config 'interface' 'lan'
        option 'ifname' 'eth0.1'
        option 'type' 'bridge'
        option 'proto' 'static'
        option 'netmask' '255.255.255.0'
        option 'ipaddr' '192.168.31.1'

config 'interface' 'wan'
        option 'ifname' 'eth1'
        option 'proto' 'dhcp'

config 'switch'
        option 'name' 'switch0'
        option 'reset' '1'
        option 'enable_vlan' '1'

config 'switch_vlan'
        option 'device' 'switch0'
        option 'vlan' '1'
        option 'ports' '0 1 2 3 5t'

Regards,

D
