According to previous disscussions on openIb fourm about ib_get_dma_mr I
have an impression that lkey returned from ib_get_dma_mr is similar to
Reserved L_Key specified in IBTA spec. But now usage in Krping is requesting
remote Read/Write premissions also, So this is confusing me, please clarify
this.
