+Netowrking with TAP device
+==========================
+
+Step 1: Configure NuttX network with ``NETUTILS_NETINIT``::
+
+  CONFIG_NETUTILS_NETINIT=y
+  CONFIG_NETINIT_IPADDR=0xc0a80868   # Target: 192.168.8.104
+  CONFIG_NETINIT_DRIPADDR=0xc0a80801 # Router: 192.168.8.1
+  CONFIG_NETINIT_NETMASK=0xffffff00  # Mask:   255.255.255.0
+
+Step 2: Create and configure a TAP device on the host::
+
+  # Create the bridge
+  sudo ip link add name br0 type bridge
+  sudo ip link set br0 up
+
+  # Create the tap interface
+  sudo ip tuntap add dev tap0 mode tap
+  sudo ip link set tap0 master br0
+  sudo ip link set tap0 up
+
+  # (optional) also attach your real NIC if you want LAN access
+  # sudo ip link set enp3s0 master br0
+
+  # Assign IP to the *bridge*
+  sudo ip addr add 192.168.8.1/24 dev br0
+
+Step 3: Launch QEMU using the TAP interface::
+
+  qemu-system-x86_64 -m 2G -smp 4 -cpu host -enable-kvm \
+  -kernel nuttx -nographic -serial mon:stdio \
+  -device e1000,netdev=mynet0 \
+  -netdev tap,id=mynet0,ifname=tap0,script=no,downscript=no
+
+Step 4: Clean up::
+
+  sudo ip link set tap0 down
+  sudo ip link set br0 down
+  sudo ip tuntap del dev tap0 mode tap
+  sudo ip link del br0
