Subject: [RFC PATCH v2 9/9] RDMA/rxe: Add RD FLUSH service support
Date:   Tue, 25 Jan 2022 16:50:41 +0800
Message-ID: <20220125085041.49175-10-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.

I have not setup a RD environment to test this protocol
