[PATCH v2 for-next 0/2] RDMA/hns: Support configuring congestion control algorithm with QP granularity

[Junxian Huang]

Commit 27c5fd271d8b ("RDMA/hns: The UD mode can only be configured
with DCQCN") adds a restriction that only DCQCN is supported for
UD QPs, but at the same time introduced other problem mistakenly.
Patch #1 reverts the previous modification and fixes the algorithm
issue for UD by configuring congestion control algorithm with QP
granularity.

Patch #2 adds support for userspace configuring congestion control
algorithm with QP granularity.

v1 -> v2:
* Not only revert but also fix the UD algorithm issue in patch #1.
