Hi all,
In the Nov 16-17th 2006 OpenFabrics Developer Summit, the
following presentation by Tom talked of negotiating
parameters at the time of establishing a connection :

Hello, Roland,
We have a customer issue regarding IPv6oIB. In the subnet, there are
limited number of MCGs supported. So when there are multiple IPv6 addresses
are assigned to one interface, each IPv6 address will have one unique
solicited-node address (depends on their groupID). Then in a la

We are experimenting with LASH. It appears that the SL2VL tables
don't get initialized unless QoS is enabled on the opensm command line
(-Q). Enabling this seems to rectify the problem. So it would appear
that LASH needs to enable this also.

OK, I've no choice to say no
Try 'man ibping' on the machine where you have OFED installed.
Also 'ibping -h' will list all available flags (without explanation).
Particularly for ibping command you need to start a Server first:
ibping -S
and then to run the client side.
Hope this helps.

All,
I've run into the following problem. Bug 335 opened to track this...
I install the alpha1 ofed 1.2 rpms on a RHEL5b2 system with its
2.6.18-1.2747.el5 kernel.
Then I build a module outside of the kernel that uses the IB verbs and
RDMA CM kernel interface. (krping). This module builds and
