Hi Sasha,
opensm creates two multicast groups for ipoib. The group corresponding to
255.255.255.255 results in an MGID with the scope as specified by the
configuration.
The one MGID for 0.0.0.1 ends up with local scope irrespective of the
configuration.
If ipoib is configured with global scope, then its join of the latter group
never
succeeds. The patch below sets the scope for both groups according to the
configuration.
