Sorry, I may have not explained it well. Lets say I do this in the
config file.

qos_vlarb_high FOOBAR
# qos_ca_vlarb_high BLAH
qos_swe_vlarb_high XYZZY

I currently expect qos_ca_vlarb_high to use the value of FOOBAR because
I commented out the field.  But it uses OSM_DEFAULT_QOS_HIGH_LIMIT
instead.  The reason is because qos_build_config() checks for NULL to
use default vs. non-default values.

p = opt->vlarb_high ? opt->vlarb_high : dflt->vlarb_high;

Under the above situation where I've commented out veral fields, opt-
>vlarb_high is always non-NULL b/c it was set to
OSM_DEFAULT_QOS_HIGH_LIMIT. Thus OSM_DEFAULT_QOS_HIGH_LIMIT is used
instead of FOOBAR.

Similar to the above issue, lets say I want to do:

qos_high_limit 8
# qos_ca_high_limit 15
# qos_swe_high_limit 15

I want qos_ca_high_limit and qos_swe_high_limit to use whatever I set in
qos_high_limit.  But the code doesn't allow for this.

I think the issue is the osm_subnet.c code did not properly check all
inputs, and subsequently some inputs used in qos_build_config() were
bad.  I think

qos_vlarb_high (null)

was something I tried that opensm seg-faulted on.

I will admit its possible that I'm fixing something that shouldn't be
fixed in the code but only in the documentation.  Currently, the
documentation indicates to me the behavior I describe above. Should we
instead tell the user they must set each of the qos_ca*, qos_swe*, etc.
fields respectively and cannot assume the "default" fields can be used
to set those other fields?  Perhaps we should just remove those
"default" fields??
