Subject: [PATCH for-next 11/20] RDMA/hns: Split CQE from MTT in hip08
Date: Wed, 30 Aug 2017 17:23:09 +0800 [thread overview]
Message-ID: <1504084998-64397-12-git-send-email-xavier.huwei@huawei.com> (raw)
In-Reply-To: <1504084998-64397-1-git-send-email-xavier.huwei-hv44wF8Li93QT0dZR+AlfA@public.gmane.org>
From: Shaobo Xu <xushaobo2-hv44wF8Li93QT0dZR+AlfA@public.gmane.org>
In hip08, the SQWQE/SGE/RQWQE and CQE have different hop num and
page size, so we need to manage the base address table of the
SQWQE/SGE/RQWQE and CQE separately.
This patch is to split CQE from MTT(SQWQE/SGE/RQWQE).
