Here's the backgrounds::
NIC card: Mellanox Technologies MT27500 Family [ConnectX-3]
Mellanox OFED driver: OFED.188.8.131.52.2
O.S: Red Hat Enterprise Linux Server release 7.0
Based on the above background,
When L2 switches is IGMP snooping on , mckey could only work when roce_mode=1.
It seems that there's some problems during join multicast group..
Did I miss anything or is there some specific configuration we have to set?
I believe RoCE multicast ONLY works on RoCE1.5 & 2.0, and supports IGMPv2
