This patch implements routine to query the PFC priority from the
adapter port.
Following are the changes implemented:
* A new FW command is implemented to query the operational/admin DCBX
configuration from the FW and obtain active priority(service
level).
* Adds support for the async event reported by FW when the PFC
priority changes. Service level is re-initialized during modify_qp
or create_ah, based on this event.
* Maintain SL value in ocrdma_dev structure and refer that as and
when needed.

The function __flush_qp() always calls the ULP's CQ completion handler
functions even if the CQ was not armed. This can crash the system if
the function pointer is NULL. The iSER ULP behaves this way: no
completion handler and never arm the CQ for notification. So now we
track whether the CQ is armed at flush time and only call the
completion handlers if their CQs were armed.
Also, if the RCQ and SCQ are the same CQ, the completion handler is
getting called twice. It should only be called once after all SQ and
RQ WRs are flushed from the QP. So rearrange the logic to fix this.

In the event flow, we currently pass only a port number in the
void *data argument. Rather than pass a pointer to the event handlers,
we should use an "unsigned long" parameter, and pass the port number
value directly.
In the future, if necessary for some events, we can use the unsigned long
parameter to pass a pointer.

In preparation for a new mlx5 device which is VPI (i.e., ports can be
either IB or ETH), move the pci device functionality from mlx5_ib
to mlx5_core.
This involves the following changes:
1. Move mlx5_core_dev struct out of mlx5_ib_dev. mlx5_core_dev
is now an independent structure maintained by mlx5_core.
mlx5_ib_dev now has a pointer to that struct.
This requires changing a lot of places where the core_dev
struct was accessed via mlx5_ib_dev (now, this needs to
be a pointer dereference).
2. All PCI initializations are now done in mlx5_core. Thus,
it is now mlx5_core which does pci_register_device (and not
mlx5_ib, as was previously).
3. mlx5_ib now registers itself with mlx5_core as an "interface"
driver. This is very similar to the mechanism employed for
the mlx4 (ConnectX) driver. Once the HCA is initialized
(by mlx5_core), it invokes the interface drivers to do
their initializations.
4. There is a new event handler which the core registers:
mlx5_core_event(). This event handler invokes the
event handlers registered by the interfaces.

This commit enhances the iwarp driver to optionally keep a log of rdma
work request timining data for kernel mode QPs. If iw_cxgb4 module option
c4iw_wr_log is set to non-zero, each work request is tracked and timing
data maintained in a rolling log that is 4096 entries deep by default.
Module option c4iw_wr_log_size_order allows specifing a log2 size to use
instead of the default order of 12 (4096 entries). Both module options
are read-only and must be passed in at module load time to set them. IE:
modprobe iw_cxgb4 c4iw_wr_log=1 c4iw_wr_log_size_order=10
The timing data is viewable via the iw_cxgb4 debugfs file "wr_log".
Writing anything to this file will clear all the timing data.
Data tracked includes:
- The host time when the work request was posted, just before ringing
the doorbell. The host time when the completion was polled by the
application. This is also the time the log entry is created. The delta
of these two times is the amount of time took processing the work request.
- The qid of the EQ used to post the work request.
- The work request opcode.
- The cqe wr_id field. For sq completions requests this is the swsqe
index. For recv completions this is the MSN of the ingress SEND.
This value can be used to match log entries from this log with firmware
flowc event entries.
- The sge timestamp value just before ringing the doorbell when
posting, the sge timestamp value just after polling the completion,
and CQE.timestamp field from the completion itself. With these three
timestamps we can track the latency from post to poll, and the amount
of time the completion resided in the CQ before being reaped by the
application. With debug firmware, the sge timestamp is also logged by
firmware in its flowc history so that we can compute the latency from
posting the work request until the firmware sees it.

Advertise a larger max read queue depth for qps, and gather the resource limits
from fw and use them to avoid exhaustinq all the resources.
Design:
cxgb4:
Obtain the max_ordird_qp and max_ird_adapter device params from FW
at init time and pass them up to the ULDs when they attach. If these
parameters are not available, due to older firmware, then hard-code
the values based on the known values for older firmware.
iw_cxgb4:
Fix the c4iw_query_device() to report these correct values based on
adapter parameters. ibv_query_device() will always return:
max_qp_rd_atom = max_qp_init_rd_atom = min(module_max, max_ordird_qp)
max_res_rd_atom = max_ird_adapter
Bump up the per qp max module option to 32, allowing it to be increased
by the user up to the device max of max_ordird_qp. 32 seems to be
sufficient to maximize throughput for streaming read benchmarks.
Fail connection setup if the negotiated IRD exhausts the available
adapter ird resources. So the driver will track the amount of ird
resource in use and not send an RI_WR/INIT to FW that would reduce the
available ird resources below zero.

The status page is mapped to user processes and allows sharing the
device state between the kernel and user processes. This state isn't
getting initialized and thus intermittently causes problems. Namely,
the user process can mistakenly think the user doorbell writes are
disabled which causes SQ work requests to never get fetched by HW.

Select the appropriate hw mtu index and initial sequence number to optimize
hw memory performance.
Add new cxgb4_best_aligned_mtu() which allows callers to provide enough
information to be used to [possibly] select an MTU which will result in the
TCP Data Segment Size (AKA Maximum Segment Size) to be an aligned value.
If an RTR message exhange is required, then align the ISS to 8B - 1 + 4, so
that after the SYN the send seqno will align on a 4B boundary. The RTR
message exchange will leave the send seqno aligned on an 8B boundary.
If an RTR is not required, then align the ISS to 8B - 1. The goal is
to have the send seqno be 8B aligned when we send the first FPDU.

Currently indirect interrupts for RDMA CQs funnel through the LLD's RDMA
RXQs, which also handle direct interrupts for offload CPLs during RDMA
connection setup/teardown. The intended T4 usage model, however, is to
have indirect interrupts flow through dedicated IQs. IE not to mix
indirect interrupts with CPL messages in an IQ. This patch adds the
concept of RDMA concentrator IQs, or CIQs, setup and maintained by the
LLD and exported to iw_cxgb4 for use when creating CQs. RDMA CPLs will
flow through the LLD's RDMA RXQs, and CQ interrupts flow through the
CIQs.
Design:
cxgb4 creates and exports an array of CIQs for the RDMA ULD. These IQs
are sized according to the max available CQs available at adapter init.
In addition, these IQs don't need FL buffers since they only service
indirect interrupts. One CIQ is setup per RX channel similar to the
RDMA RXQs.
iw_cxgb4 will utilize these CIQs based on the vector value passed into
create_cq(). The num_comp_vectors advertised by iw_cxgb4 will be the
number of CIQs configured, and thus the vector value will be the index
into the array of CIQs.

There are two kzalloc() calls which were not converted to use value of
gfp passed to create_qp_common() instead of using hardcoded GFP_KERNEL
in 40f2287bd583 ("IB/mlx4: Implement IB_QP_CREATE_USE_GFP_NOIO"). Fix
this by passing gfp value down properly.
