Sure, I'd trade this patch for another patch
that removes the mcast group pre-creation.

If no one objects, I'll remove that TS hack.

Wouldn't it be better to understand an use case of this group? It is
probably obsolete and such addition is not needed.

[PATCH] opensm/osm_qos_policy.c: fix SL for TS-precreated mcast group

2010-09-05 Thread Yevgeny Kliteynik
Assuming we still need to support TopSpin's non-compliant join
compmask for IPoIB v4 multicast group ff12:401b:::1

The group is pre-defined and maintained as a well-known
multicast group, hence it's SL needs to be fixed too in
accordance with QoS policy configuration, same as for
ff12:401b:::: MGID.
