Cyclone V Building Bootloader: Network Interfaces

I am trying to get networking working on my DE1-SoC after following this guide.

The devices listed when running
$: ip link show
are as follows.

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: can0: mtu 16 qdisc noop qlen 10
3: sit0@NONE: mtu 1480 qdisc noop qlen 1000
link/sit brd
This doesn’t seem right. Has anyone been able to get networking up after following the user guide and booting into Linux.
