This package provides the userspace daemons and a command line interface to interact with NetworkManager. Optional dependencies: * ppp: Required for establishing dial-up connections (e.g. via GSM). * dnsmasq-base/iptables: Required for creating Ad-hoc connections and connection sharing. * avahi-autoipd: Used for IPv4LL, a protocol for automatic Link-Local IP address configuration. * libteam-utils: Network Team driver allows multiple network interfaces to be teamed together and act like a single one. This process is called "ethernet bonding", "channel teaming" or "link aggregation".
