In older FW versions the completion flag was treated as the ack flag in
edpm messages. Expose the FW option of setting which mode the QP is in
by adding a flag to the qedr <-> qed API.
Flag is added for backward compatibility with libqedr.
This flag will be set by qedr after determining whether the libqedr is
using the updated version.

Add support for XRC-SRQ's and XRC-QP's for upper layer driver.
We maintain separate bitmaps for resource management for srq and
xrc-srq, However, the range in FW is one, The xrc-srq's are first
and then the srq's follow. Therefore we maintain a srq-id offset.
v2: perform cleanups if XRC bitmpas allocation fail.

Driver has an ability to initiate a recovery process as a reaction to

We still do not enable this by default though, since in some configurations
this is not desirable. E.g. this may impact other PFs/VFs.

qede (ethernet level driver) registers a callback handler.
This handler maintains eth dev state flags/bits to track error processing.
It implements in place processing part for nonsleeping context (WARN_ON
trigger), and a deferred (delayed work) part which triggers recovery
process for recoverable errors.
In later patches this atomic handler will come with more meat.
We introduce err_flags on ethdevice structure, its being used to record

Since we have kdump kernel(s) running under severe memory constraint
it makes sense to disable the qed SRIOV functionality when running the
kdump kernel as kdump configurations on several distributions don't
support SRIOV targets for saving the vmcore (see [1] for example).
Currently the qed SRIOV functionality ends up consuming memory in
the kdump kernel, when we don't really use the same.
An example log seen in the kdump kernel with the SRIOV functionality
enabled can be seen below (obtained via memstrack tool, see [2]):
dracut-pre-pivot[676]: ======== Report format module_summary: ========
dracut-pre-pivot[676]: Module qed using 149.6MB (2394 pages), peak allocation 149.6MB (2394 pages)
This patch disables the SRIOV functionality inside kdump kernel and with
the same applied the memory consumption goes down:
dracut-pre-pivot[671]: ======== Report format module_summary: ========
dracut-pre-pivot[671]: Module qed using 124.6MB (1993 pages), peak allocation 124.7MB (1995 pages)

Normally kdump kernel(s) run under severe memory constraint with the
basic idea being to save the crashdump vmcore reliably when the primary
kernel panics/hangs.
Currently the qed* ethernet driver ends up consuming a lot of memory in
the kdump kernel, leading to kdump kernel panic when one tries to save
the vmcore via ssh/nfs (thus utilizing the services of the underlying
qed* network interfaces).
An example OOM message log seen in the kdump kernel can be seen here
[1], with crashkernel size reservation of 512M.
Using tools like memstrack (see [2]), we can track the modules taking up
the bulk of memory in the kdump kernel and organize the memory usage
output as per 'highest allocator first'. An example log for the OOM case
indicates that the qed* modules end up allocating approximately 216M
memory, which is a large part of the total crashkernel size:
dracut-pre-pivot[676]: ======== Report format module_summary: ========
dracut-pre-pivot[676]: Module qed using 149.6MB (2394 pages), peak allocation 149.6MB (2394 pages)
dracut-pre-pivot[676]: Module qede using 65.3MB (1045 pages), peak allocation 65.3MB (1045 pages)
This patch reduces the default RX and TX ring count from 1024 to 64
when running inside kdump kernel, which leads to a significant memory
saving.
An example log with the patch applied shows the reduced memory
allocation in the kdump kernel:
dracut-pre-pivot[674]: ======== Report format module_summary: ========
dracut-pre-pivot[674]: Module qed using 141.8MB (2268 pages), peak allocation 141.8MB (2268 pages)
<..snip..>
[dracut-pre-pivot[674]: Module qede using 4.8MB (76 pages), peak allocation 4.9MB (78 pages)
Tested crashdump vmcore save via ssh/nfs protocol using underlying qed*
network interface after applying this patch.

The qed_chain data structure was modified in
commit 1a4a69751f4d ("qed: Chain support for external PBL") to support
receiving an external pbl (due to iWARP FW requirements).
The pages pointed to by the pbl are allocated in qed_chain_alloc
and their virtual address are stored in an virtual addresses array to
enable accessing and freeing the data. The physical addresses however
weren't stored and were accessed directly from the external-pbl
during free.
Destroy-qp flow, leads to freeing the external pbl before the chain is
freed, when the chain is freed it tries accessing the already freed
external pbl, leading to a use-after-free. Therefore we need to store
the physical addresses in additional to the virtual addresses in a
new data structure.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was detected with the help of Coccinelle.

If an event is added while the rdma workqueue is being destroyed
it could lead to several races, list corruption, null pointer
dereference during queue_work or init_queue.
This fixes the race between the two flows which can occur during
shutdown.
A kref object and a completion object are added to the rdma_dev
structure, these are initialized before the workqueue is created.
The refcnt is used to indicate work is being added to the
workqueue and ensures the cleanup flow won't start while we're in
the middle of adding the event.
Once the work is added, the refcnt is decreased and the cleanup flow
is safe to run.

for better debugging. The data dumped is the ilt (internal logical table)
and information gathered by the management firmware incase there was a
crash and driver was not able to extract the information (mdump).

This patch contains several HSI changes. The changes are part of
features like RDMA VF and OVS, the patch also contains a fix to
how the init code determines if the dmae is ready to be used.

The number of BTB blocks was modified to be different between the two chip
flavors supported (BB/K2) as a result, this lead to a re-write of selecting
the default hsi value based on the chip.
This patch creates a lookup table for hsi values per chip rather than
ask again and again for every value.

LL2 queues were a limited resource due to FW constraints.
This FW introduced a new resource which is a context based ll2 queue
(memory on host). The additional ll2 queues are required for RDMA SRIOV.
The code refers to the previous ll2 queues as ram-based or legacy, and the
new queues as ctx-based.
This change decreased the "legacy" ram-based queues therefore the first ll2
queue used for iWARP was converted to the ctx-based ll2 queue.
This feature also exposed a bug in the DIRECT_REG_WR64 macro implementation
which didn't have an effect in other use cases.

There are several wide-bus registers written to by the fw_funcs
that require using the dmae for atomicity. Therefore using the dmae
channel functionality was added to the fw_funcs file, since the code
is very similar to the previously used code, the structures used were
moved to qed_hsi. Due to FW conventions, the names of the flags in the
struct changed. Since this required slight modification in the places
that set the flags the code was modified to use GET/SET FIELD macros.

Convert storm ram line to regpair rather than two distinct u32
to better represent the u64 width of the ram.
Convert some defines to be hex instead of negative values
these values also changed by FW from previous value.
