Subject: dns: fix response to TYPE_PTR query
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=93458ac90911b84c7279070cd350405d203b702d;p=project%2Fmdnsd.git

dns: fix response to TYPE_PTR query

In case of PTR query, sending response of TYPE_A is not needed.
As per the rfc 6763, the responder in this case should send
list of its services.
