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.
