Subject: [PATCH] dnsmasq: Support add-mac option
Adds the mac address of the DNS requestor to DNS queries which
are forwarded upstream and can be used to do filtering by the
upstream servers. This only works if the requestor is on the
same subnet as the dnsmasq server
The addmac parameter can hold the following values:
0 : mac address is not added
1 : mac address is added in binary format
base64 : mac address is added base64 encoded
text: : mac address is added in human readable format
as hex and colons
