dhcp: api to enable client detect on interface
DHCPv4 aka BOOTP is somewhat awkward. A DHCP client
on an interface must receive DHCP packets to
the broadcast address or to a unicast address.
Apparently before it's been assigned to itself.
Add this new API to allow external DHCP clients
enable the DHCP client detect feature per interface.
Type: improvement
