This patch gets rid of struct ib_device_attr and cleans up drivers nicely.
It goes on top of my send_wr cleanups and the memory registration udpates
from Sagi.
[resend that hopefully comes through with the increased message limits]

Avoid the need to query for device attributes and store them in a
separate structure by merging struct ib_device_attr into struct
ib_device. This matches how the device structures are used in most
Linux subsystems.

Getting rid of ib_query_device() makes sense. Moving the device
attributes into ib_device is nice. Getting rid of ib_device_attr
is of questionable value. Why do we need to go there?
IB core API changes generate merge conflicts with feature work
in the ULPs. It’s a pain for maintainers. In this particular
case, keeping ib_device_attr would greatly reduce ULP churn.

But it will keep a totally nonsenical structure around in the future.
Note that the whole in-kernel Verbs API is a bit of a nightmare, so
there will be all kinds of larger changes. Better get it right as long
as we have as few ULPs as we have now.

Christoph,
We had a smaller volume move to cache the device attributes on the IB
device structure, and I just
realized it was dropped on the floor. Ira, that was a reviewer comment
you got when worked on OPA
and I missed the fact it didn't reach to acceptance
http://marc.info/?t=142309310600006&r=1&w=2
I vote for 1st and most doing this and taking things from there.
Or.

That's also workable.
But Ira's patch is missing ib_query_device conversion to
simply take the cached device attributes.
I'm fine with either way to go.

I'm strongly against this. As the reviews show the move is highly
confusing. The attributes don't change and there is no need to 'cache' or
'query' them. Just merge them into the device, follow years of experience
with how every other Linux subsystem does it and be done with it.

My patch eventually became the get_port_immutable call because the OPA MAD flag was going to be based per port rather than per device. This fit nicely which other devices which required different core support based on the port rather than the device. For port attributes there are values which can change and some which can not. Thus the addition of a set of immutable values which the core layer could safely store in the device structure. I could see a similar patch to Christophs to remove get_port_immutable. At the time I was just following the design pattern for the rest of the infrastructure. However, for query_port there are values which may change so we need to keep that call.
In my quick review of the device attributes I don't see anything which can change after the device is loaded by the core. So it seems Christoph patch will work.

Umm, are we on board with this one?
Christoph, would you mind rebasing it on top of 4.3-rc4 or so? I
want to develop over it so I can test it on the fly.

I can do a rebase to whatever you want. Initially this was
over your reg_api branch. Is a rebase to the latest reg_api.6
fine?

That would be great.

Avoid the need to query for device attributes and store them in a
separate structure by merging struct ib_device_attr into struct
ib_device. This matches how the device structures are used in most
Linux subsystems.
