From: Saeed Mahameed <saeedm@mellanox.com>
Preparation for upcoming ethernet driver.
- Move msix array from eq_table struct to priv since its not related to eq_table
- Intorduce irq_info struct to hold all irq information
- Move name from mlx5_eq to irq_info struct since it is irq property.
- Set IRQ affinity hints

From: Saeed Mahameed <saeedm@mellanox.com>
- Query all supported types of dev caps on driver load.
- Store the Cap data outbox per cap type into driver private data.
- Introduce new Macros to access/dump stored caps (using eat.me auto generated data types).
- obsolete SW representation of dev caps (no need for SW copy for each cap).
- modify ib driver to use new Macros for checking Caps.
- modify linux EN driver to use new Macros for checking Caps.

I don't know how stupid you think I am....
You may have removed the patch that did the refactoring, but the
completely broken code misusing the DMA API is still there in this
driver.
I said I want you to fix this fundamental problem with your driver
before making major changes like this series to it.
And I really meant it.
Don't try to side step the issue in the way that you did here.
Thanks.

Hi,
It is our interest to fix this bug here and in the existing code. We
don't like either, that our driver is mis-using the DMA API and that
it is broken on some arch's.

It is just a misunderstanding of your sentence: "I'm sorry but I'm
going to require that you fix this mis-use of the DMA API first.". I
thought that it should be fixed in this patchset first....
We were working on a fix to the existing code that is based on vmap,
and I planned to send it in a separate patch later on.
I will soon send V2 with a patch to remove the vmap() from current
code. It might be problematic to some Infiniband users of mlx5_core,
that will now need to allocate big continuous buffers, I will send the
fix to that in a separate patch in few weeks.
Thanks,
Amir
