To support QoS within and between subnets, modify IPoIB to request

Sean,
During the first post the issue of providing also the SL (and/or other
params) from the broadcast group as part of the path query was raised,
and I kind of failed to follow all the discussion that evolved... Can
you clarify if the consensus was that based on the pkey and traffic
class, the SA should return the --same-- SL (and/or other params) on
this path query as of the broadcast group?

Did you just wanted to add space/tab here? also some lines are broken at
least as my email see this patch, maybe you had some problem?

For this to take effect, don't you need to set the
IB_SA_PATH_REC_TRAFFIC_CLASS bit in the component mask?
Or.
