This patch allows the setup of simple a single interface to be automatically brought up and configured via DHCP on system startup. The interface name can be set via a configuration option. This patch does not support systemd-networkd, any complex network configuration should be done via overlay of /etc/network/interfaces or the relevant networkd configuration file [Peter: rename to BR2_SYSTEM_DHCP, tweak help text & implementation] Signed-off-by: Jérémy Rosen <jeremy.rosen@openwide.fr> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
