Disable other network interfaces when using fvdw-sl-console

[robincm]

This had me stumped for ages, was just waiting at the bit where it waits for u-boot.
I finally found a post that mentioned to try disabling all network interfaces on the PC except the one connected to the same LAN as the NAS. That sorted it for me - I had another active interface for VirtualBox host-only network, disabled this, restarted fvdw-sl-console and everything was fine.
