new DHCP server option
Some hardware can't receive a dhcp lease until they has been configured with a valid IP address.
In that circumstance, they should set to 1 the BROADCAST bit in any DHCPDISCOVER or DHCPREQUEST message.
(RFC 2131, page 24)
I have some material which didn't respect this RFC and the BROADCAST bit isn't cleared.
The DHCP server send the lease via unicast and not via broadcast.
It will be great to add in the server config, the possibilty to enable or disable the "always-broadcast" option.
