[net-next][PATCH 11/13] RDS: IB: add Fastreg MR (FRMR) detection support

Discovere Fast Memmory Registration support using IB device IB_DEVICE_MEM_MGT_EXTENSIONS. Certain HCA might support just FRMR or FMR or both FMR and FRWR. In case both mr type are supported, default FMR is used. Using module parameter 'prefer_frmr', user can choose its preferred MR method for RDS.
