From e630664c8383f300c4146d7613d61e5a8eb1f8e3 Mon Sep 17 00:00:00 2001 From: Matan Barak Date: Thu, 31 Jul 2014 11:01:29 +0300 Subject: mlx4_core: Add helper functions to support MR re-registration Add few helper functions to support a mechanism of getting an MPT, modifying it and updating the HCA with the modified object. The code takes 2 paths, one for directly changing the MPT (and sometimes its related MTTs) and another one which queries the MPT and updates the HCA via fw command SW2HW_MPT. The first path is used in native mode; the second path is slower and is used only in SRIOV.
