The rdma-core library can map doorbell register in two ways, depending
on the environment variable "MLX5_SHUT_UP_BF":
- as regular cached memory, the variable is either missing or set to
zero. This type of mapping may cause the significant doorbell
register writing latency and requires an explicit memory write
barrier to mitigate this issue and prevent write combining.
- as non-cached memory, the variable is present and set to not "0"
value. This type of mapping may cause performance impact under
heavy loading conditions but the explicit write memory barrier is
not required and it may improve core performance.
The UAR creation function maps a doorbell in one of the above ways
according to the system. In run time, it always adds an explicit memory
barrier after writing to.
In cases where the doorbell was mapped as non-cached memory, the
explicit memory barrier is unnecessary and may impair performance.
The commit [1] solved this problem for a Tx queue. In run time, it
checks the mapping type and provides the memory barrier after writing to
a Tx doorbell register if it is needed. The mapping type is extracted
directly from the uar_mmap_offset field in the queue properties.
This patch shares this code between the drivers and extends the above
solution for each of them.

The User Access Region (UAR) provides access to the hardware resources
like Doorbell Register from userspace.
It means the resources should be mapped by the kernel to some virtual
address range. There two types of memory mapping are supported by mlx5
kernel driver:
MLX5DV_UAR_ALLOC_TYPE_NC - non-cached, all writes promoted directly to
hardware.
MLX5DV_UAR_ALLOC_TYPE_BF - "BlueFlame", all writes might be cached by
CPU, and will be flushed to hardware
explicitly with memory barriers.
The supported mapping types depend on the platform (x86/ARM/etc), kernel
version, driver version, virtualization environment (hypervisor), etc.
In UAR allocation, if the system supports the allocation with non-cached
mapping, the first attempt is performed with MLX5DV_UAR_ALLOC_TYPE_NC.
Then, if this fails, the next attempt is done with
MLX5DV_UAR_ALLOC_TYPE_BF.
However, the function adds a condition for the case where the first
attempt was performed with MLX5DV_UAR_ALLOC_TYPE_BF, a condition that is
unattainable since the first attempt was always performed with
MLX5DV_UAR_ALLOC_TYPE_NC.

In the multi-process mechanism, there are things that the secondary
process does not perform itself but asks the primary process to perform
for it.
There is a special API for communication between the processes that
receives parameters necessary for the specific action required as well
as a special structure called mp_id that contains the port number of the
processes through which the initial process finds the relevant ETH
device for the processes.
One of the operations performed through this mechanism is the creation
of a memory region, where the secondary process sends the virtual
address as a parameter and the mp_id structure with the port number
inside it.
However, once the memory area management is shared between the drivers
and either port number or ETH device is no longer relevant to them, it
seems unnecessary to continue communicating between the processes
through the mp_id variable.
In this patch we will remove the use of the above structure for all MR
management, and add to the specific parameter of operations a pointer to
the common device that contains everything needed to create/register MR.

For the Ethernet RQs, if there all receiving descriptors are
exhausted, the packets being received will be dropped. This behavior
prevents slow or malicious software entities at the host from
affecting the network. While for hairpin cases, even if there is no
software involved during the packet forwarding from Rx to Tx side,
some hiccup in the hardware or back pressure from Tx side may still
cause the descriptors to be exhausted. In certain scenarios it may be
preferred to configure the device to avoid such packet drops,
assuming the posting of descriptors will resume shortly.
To support this, a new devarg "delay_drop" is introduced. By default,
the delay drop is enabled for hairpin Rx queues and disabled for
standard Rx queues. This value is used as a bit mask:
- bit 0: enablement of standard Rx queue
- bit 1: enablement of hairpin Rx queue
And this attribute will be applied to all Rx queues of a device.
The "rq_delay_drop" capability in the HCA_CAP is checked before
creating any queue. If the hardware capabilities do not support
this delay drop, all the Rx queues will still be created without
this attribute, and the devarg setting will be ignored even if it
is specified explicitly. A warning log is used to notify the
application when this occurs.
