Subject[RFC PATCH rdma-next 10/10] RDMA/rxe: Add RD FLUSH service support
Date
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
