Currently, if compiler does not support SVE, hns_roce_sve_write512() will
be a empty function, which means that this doorbell will be missed when
HNS_ROCE_QP_CAP_SVE_DIRECT_WQE is set in qp flag.
This patch ensures that driver will at least generate the DB regardless
of whether SVE DWQE is supported or not.

Currently the QPC state in HW is modified inside the critical section of
spinlock but the ibv_qp state is modified outside. There will be a short
period when QPC state has been modified to err with ibv_qp state still
remaining RTS. WQEs during this period will still be post-send by RTS-state
ibv_qp but then dropped by err-state HW with no flush CQEs generated.
To fix this problem, the QPC state in HW and ibv_qp state should be both
modified to err inside the critical section of spinlock.

As dmac is already resolved in kernel while creating AH, there is no
need to repeat the resolving in userspace. Prioritizes getting dmac
from kernel driver, unless kernel driver didn't response one.

In order to improve performance, we allow user-mode drivers to use a
larger page size to allocate WQE buffers, thereby reducing the latency
introduced by HW page switching. User-mode drivers will be allowed to
allocate WQE buffers between 4K to system page size. During
ibv_create_qp(), the driver will dynamically select the appropriate page
size based on ibv_qp_cap, thus reducing memory consumption while improving
performance.

According to Annex17_RoCEv2 (A17.4.5.2), for RoCEv2 UD, a CQE should
carry a flag that indicates if the received frame is an IPv4, IPv6 or
RoCE packet. But currently, the values of the flag corresponding to
these packet types haven't been defined yet in WC.
In UCX, 'sl' in ibv_wc for UD is used as the packet type flag, and the
packet type values have already been defined in the UCX patch of
ed28845b88
Therefore, to adapt UCX, add a create flag to hnsdv_create_qp() to allow
users to choose whether they use 'sl' in ibv_wc as service level or
packet type for UD. For the latter, obtain and translate the packet type
from CQE and fill it to 'sl' in ibv_wc.

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.
