Description: Fix improper check for IPv6 family when sending multicast
This patch fixes the proper behavior of -T (hop-limit setting) when
sending IPv6 multicast packets. Due to this bug, it was always fixed to 1.
.
SetSocketOptions() is called before socket connection, thus sa_family is
still set to 0. This is causing the if-branch in the multicast check
to always assume a non-IPv6 socket.
Checking the remote-peer family works reliably, instead.
