to me? The only way joining multicast groups can work is if it’s done in

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>It drops to the kernel alright, but there is no filtering in
IBAL. If multiple clients register for the same multicast group, that group
will get destroyed when the first client deregisters. Makes it very hard to
have multiple QPs on the same port in the same multicast group.</span><span
