From 9b5a30dc41c7455a17c88ed1a3677ba5f937f31d Mon Sep 17 00:00:00 2001 From: Guillaume Subiron Date: Sat, 19 Dec 2015 22:25:02 +0100 Subject: slirp: Make udp_attach IPv6 compatible A unsigned short is now passed in argument to udp_attach instead of using a hardcoded "AF_INET" to call qemu_socket(). This prepares for IPv6 support.
