For some mlx5 HW models (CX4, CX4Lx), the VF driver needs to put part
of the packet headers on the TX descriptor so the e-switch can do proper
matching and steering. This is called "min-inline", it's advertized to
the VF by the FW and also enforced on them by the HW, such that if they
don't obey, their packets are dropped.
SRIOV VF libmlx5 instances should take into account the min-inline
value of their vports. For that end, we provide this value through
the vendor response part of init_ucontext command.
The min inline value is reported in a way which will let newer libmlx5
instances realize that they are running over an older kernel and act
accordingly (e.g apply some educated guess).

Function rx_data(), which handles ingress CPL_RX_DATA messages, was
always sending an RX_DATA_ACK with the goal of updating the credits.
However, if the RDMA connection is moved out of FPDU mode abruptly,
then it is possible for iw_cxgb4 to process queued RX_DATA CPLs after HW
has aborted the connection. These CPLs should not trigger RX_DATA_ACKS.
If they do, HW can see a READ after DELETE of the DB_LE hash entry for
the tid and post a LE_DB HashTblMemCrcError.

Commit ad61a4c7a9b7 ("iw_cxgb4: don't block in destroy_qp awaiting
the last deref") introduced a bug where the RDMA QP EQ queue memory
(and QIDs) are possibly freed before the underlying connection has been
fully shutdown. The result being a possible DMA read issued by HW after
the queue memory has been unmapped and freed. This results in possible
WR corruption in the worst case, system bus errors if an IOMMU is in use,
and SGE "bad WR" errors reported in the very least. The fix is to defer
unmap/free of queue memory and QID resources until the QP struct has
been fully dereferenced. To do this, the c4iw_ucontext must also be kept
around until the last QP that references it is fully freed. In addition,
since the last QP deref can happen in an IRQ disabled context, we need
a new workqueue thread to do the final unmap/free of the EQ queue memory.

With the addition of the IB/Core drain API, iw_cxgb4 supported drain
by watching the CQs when the QP was out of RTS and signalling "drain
complete" when the last CQE is polled. This, however, doesn't fully
support the drain semantics. Namely, the drain logic is supposed to signal
"drain complete" only when the application has _processed_ the last CQE,
not just removed them from the CQ. Thus a small timing hole exists that
can cause touch after free type bugs in applications using the drain API
(nvmf, iSER, for example). So iw_cxgb4 needs a better solution.
The iWARP Verbs spec mandates that "_at some point_ after the QP is
moved to ERROR", the iWARP driver MUST synchronously fail post_send and
post_recv calls. iw_cxgb4 was currently not allowing any posts once the
QP is in ERROR. This was in part due to the fact that the HW queues for
the QP in ERROR state are disabled at this point, so there wasn't much
else to do but fail the post operation synchronously. This restriction
is what drove the first drain implementation in iw_cxgb4 that has the
above mentioned flaw.
This patch changes iw_cxgb4 to allow post_send and post_recv WRs after
the QP is moved to ERROR state for kernel mode users, thus still adhering
to the Verbs spec for user mode users, but allowing flush WRs for kernel
users. Since the HW queues are disabled, we just synthesize a CQE for
this post, queue it to the SW CQ, and then call the CQ event handler.
This enables proper drain operations for the various storage applications.

Saeed Mahameed says:
====================
mlx5 4K UAR
The following series of patches optimizes the usage of the UAR area which is
contained within the BAR 0-1. Previous versions of the firmware and the driver
assumed each system page contains a single UAR. This patch set will query the
firmware for a new capability that if published, means that the firmware can
support UARs of fixed 4K regardless of system page size. In the case of
powerpc, where page size equals 64KB, this means we can utilize 16 UARs per
system page. Since user space processes by default consume eight UARs per
context this means that with this change a process will need a single system
page to fulfill that requirement and in fact make use of more UARs which is
better in terms of performance.
In addition to optimizing user-space processes, we introduce an allocator
that can be used by kernel consumers to allocate blue flame registers
(which are areas within a UAR that are used to write doorbells). This provides
further optimization on using the UAR area since the Ethernet driver makes
use of a single blue flame register per system page and now it will use two
blue flame registers per 4K.
The series also makes changes to naming conventions and now the terms used in
the driver code match the terms used in the PRM (programmers reference manual).
Thus, what used to be called UUAR (micro UAR) is now called BFREG (blue flame
register).
In order to support compatibility between different versions of
library/driver/firmware, the library has now means to notify the kernel driver
that it supports the new scheme and the kernel can notify the library if it
supports this extension. So mixed versions of libraries can run concurrently
without any issues.

Current check requests that new fields in struct
mlx5_ib_alloc_ucontext_req_v2 that are not known to the driver be zero.
This was introduced so new libraries passing additional information to
the kernel through struct mlx5_ib_alloc_ucontext_req_v2 will be notified
by old kernels that do not support their request by failing the
operation. This schecme is problematic since it requires libmlx5 to issue
the requests with descending input size for struct
mlx5_ib_alloc_ucontext_req_v2.
To avoid this, we require that new features that will obey the following
rules:
If the feature requires one or more fields in the response and the at
least one of the fields can be encoded such that a zero value means the
kernel ignored the request then this field will provide the indication
to the library. If no response is required or if zero is a valid
response, a new field should be added that indicates to the library
whether its request was processed.

This establishes a solid naming conventions for UARs. A UAR (User Access

Demoting simple flow steering rule priority (for DPDK) was achieved by
wrapping FW commands MLX4_QP_FLOW_STEERING_ATTACH/DETACH for the PF
as well, and forcing the priority to MLX4_DOMAIN_NIC in the wrapper
function for the PF and all VFs.
In function mlx4_ib_create_flow(), this change caused the main rule
creation for the PF to be wrapped, while it left the associated
tunnel steering rule creation unwrapped for the PF.
This mismatch caused rule deletion failures in mlx4_ib_destroy_flow()
for the PF when the detach wrapper function did not find the associated
tunnel-steering rule (since creation of that rule for the PF did not
go through the wrapper function).
Fix this by setting MLX4_QP_FLOW_STEERING_ATTACH/DETACH to be "native"
(so that the PF invocation does not go through the wrapper), and perform
the required priority demotion for the PF in the mlx4_ib_create_flow()
code path.
