Subject: [PATCH 4/4] libhns: Add a judgment to the congestion control
|
||
|
|
algorithm
|
||
|
|
|
||
|
|
driver inclusion
|
||
|
|
category: bugfix
|
||
|
|
bugzilla: https://gitee.com/src-openeuler/rdma-core/issues/I7A7HI
|
||
|
|
|
||
|
|
---------------------------------------------------------------
|
||
|
|
|
||
|
|
The congestion control algorithm is used only when the comp_mask flag
|
||
|
|
HNSDV_QP_INIT_ATTR_MASK_QP_CONGEST_TYPE is seted.
|
||
|
|
|
||
|
|
A check on comp_mask is added to prevent invalid parameter errors caused
|
||
|
|
by unconfigured congestion control algorithm types.
|
||
|
|
|
||
|
|
Fixes: 7623f24781f1 ("libhns: Support congestion control algorithm configuration")
