 the RTL simulation to read and write from a file. Take a look at tests/blkdev.c
 for an example of how Rocket can program the block device controller.
 
-## Using the network device
-
-Testchipip also includes a basic ethernet controller (SimpleNIC). The simulator
-provides a way to connect this up to a tap interface and thus interact with
-rocketchip as if it was a regular network node.
-
-First set up the tap interface. If you want to run the simulation as a regular
-user (recommended), use the following commands.
-
-    sudo ip tuntap add mode tap dev tap0 user $USER
-    sudo ip link set tap0 up
-    sudo ip addr add 192.168.1.1/24 dev tap0
-
-Then build the SimNetworkConfig and pass it the name of the tap interface
-
-    make CONFIG=SimNetworkConfig
-    ./simulator-example-SimNetworkConfig +netdev=tap0 ../tests/pingd.riscv
-
-Then run ping in a separate terminal.
-
-    ping 192.168.1.2
-
-You should now see the ping responses come back. The `pingd.riscv` program
-will also log each packet it receives.

 ## Adding an MMIO peripheral
 
 You can RocketChip to create your own memory-mapped IO device and add it into
