[Voyage-linux] net4511 network throughput

[Jeff Loughridge]

I'm using Voyage 0.9.1 on my net4511 router. I'm testing network
throughput using iperf (UDP) between the wired Ethernet ports. The
throughput is about 8 Mb/s. I suspected the ports autonegotiated to 10
Mb/s but ethtool indicates 100 Mb/s.

The only change I've made to Voyage is unpacking/repacking initrd to
load the ide-generic driver. The net4511 wouldn't mount the root
filesystem without that change.

Is anyone seeing higher throughput on the net4511? If so, were tweaks required?
