[ Upstream commit 65197a4 ]
Library expects ilog2 of psn_size while calculating the stride.
ilog32 returns log2(v) + 1 and the calculation fails since
the psn size is a power of 2 value. Fix by passing psn_size - 1.

When HW is in resetting stage, we could not poll back all the
expected work completions as the HW won't generate cqe anymore.
This patch allows driver to compose the expected wc instead of the HW
during resetting stage. Once the hardware finished resetting, we can
poll cq from hardware again.

Currently, there is a repeated judgement in check_qp_congest_type
whenever enable LDCP or HC3, the congest type flags all will be set
on LDCP.
This patch fixes this bug and replace a corrupt patch--0077, which
has a change that directly acts on patch but not code. This act
will disrupt the patch format.

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.

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.
