What's v_key ?

Thanks for the heads up.

Don't forget the simulator too :-)

So here's my take:

1. In terms of ibdm and the simulator (ibmgtsim), I believe these are
properly located in the OpenIB tree. I also don't think I personally
have sufficient experience with them as yet so it is too soon at least
for me. I also haven't seen anyone else post any experiences with this
or opinion on it on the list.

2. In terms of ibis, I have superficially played with this tool.
Although I think there are different approaches to the problem which
this tool addresses, Although I don't see the urgency in moving it to
the trunk (it is every bit just as useful where it is located in the
tree, perhaps just a hair less convenient), I am open to moving this to
the trunk as I think it is useful. This would be conditional on
your/Mellanox support for this. What is the commitment to this ? 

Also, what do others on the list think ? Has anyone used ibis aside from
me and Mellanox ?

Also, a detail: Where would it be moved ? Under
userspace/management/ibis or somewhere else ?
