dhcp4d: send replies as unicast using raw sockets
...
Preferring unicast over multicast (which hogs a lot of airtime on WiFi networks)
is a best practice.
Some device/access point vendor combinations even seem to entirely eat (some?)
broadcast traffic (sometimes), e.g. my Apple iPhone SE/Ubiquiti UAP-AC-HD, so
that using unicast is required for reliable WiFi.
