* RDMA/core: Add signature attrs element for ib_mr structureMax Gurtovoy2019-06-241-0/+2
| | | | | | | | | | | | | This element will describe the needed characteristics for the signature operation per signature enabled memory region (type IB_MR_TYPE_INTEGRITY). Also add meta_length attribute to ib_sig_attrs structure for saving the mapped metadata length (needed for the new API implementation).
