Hi,
I am trying to understand remapping functionality and fmr_pool.c.
Looking back at old thread:
http://lists.openfabrics.org/pipermail/general/2006-February/017198.html
Can you please confirm whether my understanding is correct or not.

Hi,
Did you get chance to merge below be2net patch for supporing RoCE driver?
http://marc.info/?l=linux-rdma&m=133279326217836&w=2
Once this is done, Roland can merge ocrdma RoCE driver addition to his tree.
This NIC driver patch is required to merge ocrdma patch.
When can I expect this patch to
Got it. You did mention about typedef in email chain, but I understood as
different way to achieve same.
I reviewed my code and found that most of the fields between driver-adapter

I see couple of comments on rsvd words.
They were primarily not introduced for alignment. But there are other new
features that we will be adding with new set of hardware and firmware updates.
I don't want to change the user-kernel interface at such stage by modifying the
size of the structure.

You are right, cq_lock will result into dead lock.
