To make it easier for users to test and evaluate the FVP, including
testing inbound network connections, enable the openssh SSH server by
default and map to port 8022 on the host.

Update fvp-baser-aemv8r64 documentation accordingly in new "Networking"

  - Escape to telnet console with ``ctrl+]``.
  - Run ``quit`` to close the session.
+### Networking
+The FVP is configured by default to use "user-mode networking", which simulates
+an IP router and DHCP server to avoid additional host dependencies and
+networking configuration. Outbound connections work automatically, e.g. by
+    wget
+Inbound connections require an explicit port mapping from the host. By default,
+port 8022 on the host is mapped to port 22 on the FVP, so that the following
+command will connect to an ssh server running on the FVP:
+    ssh root@localhost -p 8022
+Note that user-mode networking does not support ICMP, so `ping` will not work.
+For more information about user-mode networking, please see
 ### File sharing between host and fvp
 It is possible to share a directory between the host machine and the fvp using
 the virtio P9 device component included in the kernel. To do so, create a
