Subject: [PATCH for-next 4/4] RDMA/hns: Update the PD&CQE&MTT specification in hip08
Date: Sat, 30 Sep 2017 17:29:01 +0800	[thread overview]
Message-ID: <1506763741-81429-5-git-send-email-xavier.huwei@huawei.com> (raw)
In-Reply-To: <1506763741-81429-1-git-send-email-xavier.huwei@huawei.com>

This patch updates the PD specification to 16M for hip08. And it
updates the numbers of mtt and cqe segments for the buddy.

As the CQE supports hop num 1 addressing, the CQE specification is
64k. This patch updates to set the CQE specification to 64k.
