Subject: [PATCH for-next 3/9] RDMA/hns: Add interception for resizing SRQs
Date: Mon, 7 Sep 2020 21:36:42 +0800 [thread overview]
Message-ID: <1599485808-29940-4-git-send-email-liweihang@huawei.com> (raw)
In-Reply-To: <1599485808-29940-1-git-send-email-liweihang@huawei.com>
From: Yangyang Li <liyangyang20@huawei.com>
HIP08 doesn't support modifying the maximum number of outstanding WR in an
SRQ. However, the driver does not return a failure message, and users may
mistakenly think that the resizing is executed successfully. So the driver
needs to intercept this operation.
