Subject: [RFC PATCH rdma-next 10/10] RDMA/rxe: Add RD FLUSH service support
Date: Tue, 28 Dec 2021 16:07:17 +0800 [thread overview]
Message-ID: <20211228080717.10666-11-lizhijian@cn.fujitsu.com> (raw)
In-Reply-To: <20211228080717.10666-1-lizhijian@cn.fujitsu.com>
Although the SPEC said FLUSH is supported by RC/RD/XRC services, XRC has
not been supported by the rxe.
So XRC FLUSH will not be supported until rxe implements XRC service.
Signed-off-by: Li Zhijian <lizhijian@cn.fujitsu.com>

I have not setup a RD environment to test this protocol
