Hi, Zhijian
I am making tests with it. Except rc, other modes are supported? such as
rd, xrc?
Only RC is implemented for FLUSH, current RXE only supports RC service[1].
BTW, XRC is on the way in Bob's patch IIRC.

40 * IBA header types and methods

42 * Some of these are for reference and completeness only since
43 * rxe does not currently support RD transport
44 * most of this could be moved into IB core. ib_pack.h has
45 * part of this but is incomplete
