2017-01-06llmnr-query: Add support for FreeBSD and DarwinTobias Klauser1-2/+34
Make llmnr-query work on FreeBSD and Darwin by using sendmsg() to send UDP packets. Using sendto() doesn't seem to work for IPv6 sockets. Also specify the size of the corresponding sockaddr type, not of sockaddr_storage. Tested on FreeBSD 11.0, Mac OS X 10.11. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
