Subject: [PATCH for-rc 5/7] RDMA/hns: The UD mode can only be configured with DCQCN
Date: Tue, 17 Oct 2023 20:52:37 +0800 [thread overview]
Message-ID: <20231017125239.164455-6-huangjunxian6@hisilicon.com> (raw)
In-Reply-To: <20231017125239.164455-1-huangjunxian6@hisilicon.com>
From: Luoyouming <luoyouming@huawei.com>
Due to hardware limitations, only DCQCN is supported for UD. Therefore, the
default algorithm for UD is set to DCQCN.
Fixes: f91696f2f053 ("RDMA/hns: Support congestion control type selection according to the FW")
