Subject: [PATCH for-next 03/12] RDMA/hns: Force srq_limit to 0 when creating SRQ
Date: Sat, 30 Jan 2021 16:58:01 +0800 [thread overview]
Message-ID: <1611997090-48820-4-git-send-email-liweihang@huawei.com> (raw)
In-Reply-To: <1611997090-48820-1-git-send-email-liweihang@huawei.com>
From: Wenpeng Liang <liangwenpeng@huawei.com>
According to the IB Specification, srq_limit shouldn't be configured
during SRQ creation. If a user set srq_limit at this time, the driver
should forced it to zero, or the result of creating SRQ will conflict with
the result of querying SRQ.
Fixes: c7bcb13442e1 ("RDMA/hns: Add SRQ support for hip08 kernel mode")
