Subject: [PATCH for-next 2/3] RDMA/hns: Reduce the maximum number of extend SGE per WQE
Date: Thu, 26 Mar 2020 11:40:17 +0800
Message-ID: <1585194018-4381-3-git-send-email-liweihang@huawei.com> (raw)
In-Reply-To: <1585194018-4381-1-git-send-email-liweihang@huawei.com>

From: Lang Cheng <chenglang@huawei.com>

Just reduce the default number to 64 for backward compatibility, the driver
can still get this configuration from the firmware.
