[Qemu-devel] [PULL 13/17] slirp: Adding family argument to tcp_fconnect()

[Jason Wang <jasowang@redhat.com>]

From: Guillaume Subiron <maethor@subiron.org>

This patch simply adds a sa_family_t argument to remove the hardcoded
"AF_INET" in the call of qemu_socket().

This prepares for IPv6 support.
