[PATCH] IB: RMPP fixes
- Fix payload length of middle RMPP sent segments. Middle payload
lengths should be 0 on the send side.
(This is perhaps a compliance and should not be an interop issue as
middle payload lengths are supposed to be ignored on receive).
- Fix length in first segment of multipacket sends
(This is a compliance issue but does not affect at least OpenIB to
OpenIB RMPP transfers).
