parentRDMA/core: Introduce new header file for signature operations (diff)
RDMA/core: Save the MR type in the ib_mr structure
This is a preparation for the signature verbs API change. This change is needed since the MR type will define, in the upcoming patches, the need for allocating internal resources in LLD for signature handover related operations. It will also help to make sure that signature related functions are called with an appropriate MR type and fail otherwise. Also introduce new mr types IB_MR_TYPE_USER, IB_MR_TYPE_DMA and IB_MR_TYPE_DM for correctness.
