    Dror> It is not possible to turn off PD check on a MR in

It's no big deal to create one more MR with translation off for each
kernel PD (in fact mthca does it already for access to address
vectors).  So this is a perfectly reasonable solution, it just means
our API can't perfectly match the verbs extensions.

    Dror> Once we get to verbs extensions, you can configure Arbel to

Yes, I see how Arbel has full support for the base memory management
extensions including reserved L_Key.  I would assume we will allow use
of reserved L_Key for all kernel QPs (and no userspace QPs).

Thanks,
