Unable to subscribe server to a multicast channel

[vianeostech]

1. What did you do? If possible, provide a simple script for reproducing the error.

I tried to subscribe a TCP server to a multicast channel : 

$ret = socket_set_option( $socket, IPPROTO_IP, MCAST_JOIN_GROUP, [ 'group' => '225.0.0.1', 'interface' => 'eth0' ] );

2. What did you expect to see?

TCP server is able to suscribe to multicast channel.

3. What did you see instead?

PHP Warning:  socket_set_option(): Unable to set socket option [92]: Protocol not available

4. What version of OpenSwoole are you using (show your php --ri openswoole)?
