Comment 12 for bug 1529815

I think during the fix of:

https://bugs.launchpad.net/ubuntu/+source/isc-dhcp/+bug/1401141

I accidentally missed the following:

> + /* Set the broadcast flag */
> + ip->client->config->bootp_broadcast_always = 1;
> +

in find_subnet.

This comes from: dhcp-4.2.5-lpf-ib.patch in tag "dhcp-4.2.5-30.fc20" from
pkgs.fedoraproject.org/git/rpms/dhcp.git (since all IB patches are coming
from fedora project).

I'll review this and provide a PPA, asking for feedback.
