[kai.kang at windriver.com]

From: Kai Kang <kai.kang at windriver.com>

Configure wired network interface with dhcp when use systemd as default init
manager.

Test steps:
1 $ . oe-init-build-env
2 set MACHINE and systemd as default int manager in local.conf
  DISTRO_FEATURES_append = " systemd"
  DISTRO_FEATURES_BACKFILL_CONSIDERED += "sysvinit"
  VIRTUAL-RUNTIME_login_manager = "shadow-base"
  VIRTUAL-RUNTIME_init_manager = "systemd"
  VIRTUAL-RUNTIME_initscripts = "systemd-compat-units"
  MACHINE ?= "genericx86-64"

3 bitbake core-image-minial
4 show ip status:
$ ip ad
  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

5 when connman is installed, 2 dynamic ips are allocated for enp0s25 and both work:
