The default version provided by "ethtool -i" it the correct way
to identify Driver version. There is no need to overwrite it.

The rdma_cm must be used single threaded.
This appears to be a bug in the design, as it does have lots of locking
that seems like it should allow concurrency. However, when it is all said
and done every single place that uses the cma_exch() scheme is broken, and
all the unlocked reads from the ucma of the cm_id data are wrong too.
syzkaller has been finding endless bugs related to this.
Fixing this in any elegant way is some enormous amount of work. Take a
very big hammer and put a mutex around everything to do with the
ucma_context at the top of every syscall.

Currently qplib layer function calls has not been replaced due to

Moving all the fast path doorbell functions at one place under
qplib_res.h. To pass doorbell record information a new structure
bnxt_qplib_db_info has been introduced. Every roce object holds an
instance of this structure and doorbell information is initialized during
resource creation.
When DB is rung only the current queue index is read from hardware ring
and rest of the data is taken from pre-initialized dbinfo structure.

is introduced to describe the bar register. each object which deals with
mmio space should have a descriptor structure. This structure specifically
hold DB register information. Thus, slow path creq structure now hold a

Further cleanup the rcfw structure to introduce the command queue context

passed in bnxt_re_net_ring_alloc() function.
The caller of bnxt_re_net_ring_alloc should fill in the list of attributes

At top level there are three major data structure addition. viz
bnxt_qplib_hwq_attr, bnxt_qplib_sg_info and bnxt_qplib_tqm_ctx
Intorduction of first data structure reduces the arguments list to
bnxt_re_alloc_init_hwq() function. There are changes all over the driver
code to incorporate this new structure. The caller needs to fill the
attribute data structure and pass to this function.
The second data structure is to pass memory region description
viz. sghead, page_size and page_shift. There are changes all over the
driver code to initialize bnxt_re_sg_info data structure. The new data
structure helps to reduce the argument list of __alloc_pbl() function
call.
Till now the TQM rings related members were not collected under any
specific data-structure making it hard to manage. The third data
sctructure bnxt_qplib_tqm_ctx is added to refactor the TQM queue
allocation and initialization.

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 found with the help of Coccinelle.

HiP08 RoCE hardware lacks ability(a known hardware problem) to flush
outstanding WQEs if QP state gets into errored mode for some reason. To
overcome this hardware problem and as a workaround, when QP is detected to
be in errored state during various legs like post send, post receive
etc[1], flush needs to be performed from the driver.
The earlier patch[1] sent to solve the hardware limitation explained in
the cover-letter had a bug in the software flushing leg. It acquired mutex
while modifying QP state to errored state and while conveying it to the
hardware using the mailbox. This caused leg to sleep while holding
spin-lock and caused crash.
Suggested Solution: we have proposed to defer the flushing of the QP in
the Errored state using the workqueue to get around with the limitation of
our hardware.
This patch specifically adds the calls to the flush handler from where
parts of the code like post_send/post_recv etc. when the QP state gets
into the errored mode.

This is a merge error on my part - the driver was merged into mainline
by commit c5951e7c8ee5 ("Merge tag 'mips_5.6' of git://../mips/linux")
over a week ago, but nobody apparently noticed that it didn't actually
build due to still having a reference to the devm_ioremap_nocache()
function, removed a few days earlier through commit 6a1000bd2703 ("Merge
tag 'ioremap-5.6' of git://../ioremap").
Apparently this didn't get any build testing anywhere. Not perhaps all
that surprising: it's restricted to 64-bit MIPS only, and only with the
new SGI_MFD_IOC3 support enabled.
I only noticed because the ioremap conflicts in the ARM SoC driver
update made me check there weren't any others hiding, and I found this
one.

Pull vfs file system parameter updates from Al Viro:
"Saner fs_parser.c guts and data structures. The system-wide registry
of syntax types (string/enum/int32/oct32/.../etc.) is gone and so is
the horror switch() in fs_parse() that would have to grow another case
every time something got added to that system-wide registry.
New syntax types can be added by filesystems easily now, and their
namespace is that of functions - not of system-wide enum members. IOW,
they can be shared or kept private and if some turn out to be widely
useful, we can make them common library helpers, etc., without having
to do anything whatsoever to fs_parse() itself.
And we already get that kind of requests - the thing that finally
pushed me into doing that was "oh, and let's add one for timeouts -
things like 15s or 2h". If some filesystem really wants that, let them
do it. Without somebody having to play gatekeeper for the variants
blessed by direct support in fs_parse(), TYVM.
Quite a bit of boilerplate is gone. And IMO the data structures make a
lot more sense now. -200LoC, while we are at it"

The configuration of the OCTEONTX XCV_DLL_CTL register via
xcv_init_hw() is such that the RGMII RX delay is bypassed
leaving the RGMII TX delay enabled in the MAC:
/* Configure DLL - enable or bypass
* TX no bypass, RX bypass
*/
cfg = readq_relaxed(xcv->reg_base + XCV_DLL_CTL);
cfg &= ~0xFF03;
cfg |= CLKRX_BYP;
writeq_relaxed(cfg, xcv->reg_base + XCV_DLL_CTL);
This would coorespond to a interface type of PHY_INTERFACE_MODE_RGMII_RXID
and not PHY_INTERFACE_MODE_RGMII.
Fixing this allows RGMII PHY drivers to do the right thing (enable
RX delay in the PHY) instead of erroneously enabling both delays in the
PHY.
