man: split out a paragraph and shorten the text about sd-network-generator

interface which has the address. When no MAC address is specified, the policies are applied
to all interfaces. This kernel command line argument can be specified multiple times. This
argument is not directly read from <command>systemd-udevd</command>, but read and converted
to a .link file by <command>systemd-network-generator</command>. So, to make this argument
take effect, <filename>systemd-network-generator.service</filename> must be enabled and
