[Buildroot] [PATCH 1/1] dhcpcd: systemv and systemd services conflict with NetworkManager

[Jim Brennan]

When NetworkManager and dhcpcd packages are both enabled,
dhcpcd services and NetworkManager both spawn dhcpcd.  This causes
the network port to retrieve an IP address and later lose it a few
seconds after startup.

This patch prevents dhcpcd services from launching dhcpcd if
NetworkManager is enabled.
