Bug #186

Description

By default, openwrt configures the first radio + ethernet port as a bridge across the local switch, and wireless. It appears to be picking up the mac address of the wireless interface when doing so, and works pretty good, except that thus far I’ve been unable to coax greater than 60Mbit performance out of it.

It would be useful to be able to NOT configure the ethernet interface as a bridge, but as a real, separate wired interface for my ongoing investigation to QoS and multicast issues, in particular.

Attempting to do so, results in the following - even after disabling the wireless interfaces entirely.

root@aitne:~# ifconfig eth0
eth0 Link encap:Ethernet HWaddr C4:3D:C7:B0:AE:36
inet addr:192.168.130.1 Bcast:192.168.130.255 Mask:255.255.255.0

100% drops.

Even though, the other ethernet interface is fine

eth1 Link encap:Ethernet HWaddr C4:3D:C7:B0:AE:37
inet addr:192.168.115.171 Bcast:192.168.115.255 Mask:255.255.255.0

openwrt bleeding edge, r26878

There are no revealing errors in the log, this is all that is said about eth0 and eth1.

root@aitne:~# dmesg | grep eth0
