Comment 5 for bug 1433290

By moving the Mustang box into a lab that had a gigibit connection, it immediately connected with the network. It's surprising that the network worked just fine on a 100Kb connection when running tftpboot and when installing Ubuntu, but not when running Ubuntu. This looks like a limitation in the Ubuntu 14.04 driver for aarch64, not with the Mustang box itself. It's just too bad that this limitation isn't documented anywhere, other than this bug report.
