1. The hns hardware logic requires wr->num_sge to be 1 when
performing atomic operations. The code does not judge this
condition, and the current patch adds this constraint.
2. In the sq inline scenario, when num_sge in post_send is not 1, sge
array appears in the for loop without rotation and directly copy
out of bounds.
3. Currently local invalidate operation don't work properly.
Disable it for the time being.
HIP08 and HIP09 hardware does not support this feature, so
delete the associated code.

Some Kunpeng SoCs do not support the DWQE through NEON
instructions. In this case, the IO path works normally,
but the performance will deteriorate.
For these SoCs that do not support NEON DWQE, they support
DWQE through SVE instructions. This patch supports SVE DWQE
to guarantee the performance of these SoCs. In addition, in
this scenario, DWQE only supports acceleration through SVE's
ldr and str instructions. Other load and store instructions
also cause performance degradation.

Added the use of direct verbs to implement QP-level
user-configurable congestion control algorithms. Among them,
the user mode driver mainly provides interfaces for users to
choose, and the kernel mode driver is responsible for filling
the resources of different algorithms and providing the
supported algorithm types for user mode.
At the same time, provide a direct verbs interface for users to
query the type of congestion control algorithm.

Add an interface to the user space, which is used to receive
the kernel reset state. After receiving the reset flag, the
user space stops sending db.

DCA(Dynamic context attachment) support many RC QPs to share the WQE
buffer in a memory pool, this help reducing the memory consumption
when there are many QPs are inactive.
