[PATCH OLK-6.6 0/2] infiniband/hw/hiroce3: Add Huawei Intelligent Network Card RDMA Driver
From: w00623716 <wushuai51@huawei.com> driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I9EMOF CVE: NA --------------------------------- The RDMA driver supports the following features: Supports Huawei SP600 series NICs; Supports RoCEv2; Supports RoCE XRC, UD, UC, and RC modes; Supports RoCE UC, RC, and UD local switching; Supports RoCE MR, PD, CQ, QoS, QP, and SRQ management; Supports RoCE congestion control; Supports RoCE Bond; Supports RoCE FLR; Supports RoCE entry specifications; Supports RoCE error detection and reporting; Signed-off-by: Wu Shuai
