Stop DHCP INFORM flooding

Background

Windows 7 among others ask for proxy settings using DHCP. The issue is that they do not stop asking until they have received an answer. This results in that the log contains a lot information about these requests, an example can be found below.

2017:07:30-00:12:03 firewall-1 dhcpd: DHCPINFORM from 192.168.188.213 via eth3
2017:07:30-00:12:03 firewall-1 dhcpd: DHCPACK to 192.168.188.213 (00:50:56:ab:38:53) via eth3

2017:07:30-00:14:03 firewall-1 dhcpd: DHCPACK to 192.168.188.213 (00:50:56:ab:38:53) via eth3
2017:07:30-00:14:03 firewall-1 dhcpd: DHCPINFORM from 192.168.188.213 via eth4

Add the following option to the DHCP server:

dhcp-option=252,"\n"
