| 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. | |
