[ofa-general] RE: Does the CMA user space support join multicast for IPv6 too?

Hmm... I don't think so.  It looks like the librdmacm and rdma_cm kernel modules
could support it with a small change.  The kernel module calls ip_ib_mc_map() to
map IP addresses to MGIDs, which only works with IPv4.

Does ipoib map IPv6 multicast addresses to MGIDs directly?
