• Blacklist feature added (16 blacklisted subnets allowed).
• Socket limit increased to 16 sockets, moved to #define.

The first is most interesting. Say you have two networks bound together with site-to-site tunnels, repeating mDNS over the tunnel... And there are Chromecasts, or Apple TV's at both ends. Even if you had firewall rules to block traffic, the devices would still show up (albeit be defective) on the opposite network.

The new blacklist flag allows you to filter such devices out by specifying their subnet (or individual addresses, although having such "private" devices on their own subnet might be a good idea).

Example:

# Repeat mDNS packets between eth1 and vti0, while ignoring packets from 172.20.20.0/24
mdns-repeater -b 172.20.20.0/24 eth1 vti0

The attached mips64 build has been tested on Ubiquiti Edgerouter Lite on EdgeOS 1.9.0. It is built statically using musl as libc.
