Hi Michael,
 
Yesterday, when I ran regression on the gen2_devel driver with the multicast patches, the opensm got an errors on multicast join (described below).
 
Can you check it?
 
Thx,
Yohad

c0-7 (port 2) is trying to create mgroup, but the component mask is missing some bits:
 
__osm_mcmr_rcv_join_mgrp: ERR 1B11: 
method = SubnAdmSet, 
scope_state = 0x1, 
component mask = 0x0000000000010083, 
expected comp mask = 0x00000000000130c7, 
MGID: 0xff12601bffff0000 : 0x0000000000000002 
from port 0x0002c90200209622
 
Missing bits in component mask for creating mcgroup:
 
IB_MCR_COMPMASK_QKEY    
IB_MCR_COMPMASK_TCLASS  
IB_MCR_COMPMASK_SL      
IB_MCR_COMPMASK_FLOW
