From 2cb2912d65633e751d3f8397377174501412aa47 Mon Sep 17 00:00:00 2001 From: "santosh.shilimkar@oracle.com" Date: Tue, 1 Mar 2016 15:20:52 -0800 Subject: 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. Default MR is still kept as FMR against what everyone else is following. Default will be changed to FRMR once the RDS performance with FRMR is comparable with FMR. The work is in progress for the same.
