From 9ac7c4bcd383adbac9ad02ec033cce9a3a261d28 Mon Sep 17 00:00:00 2001 From: Max Gurtovoy Date: Tue, 11 Jun 2019 18:52:44 +0300 Subject: [PATCH] RDMA/mlx5: Pass UMR segment flags instead of boolean UMR ctrl segment flags can vary between UMR operations. for example, using inline UMR or adding free/not-free checks for a memory key. This is a preparation commit before adding new signature API that will not need not-free checks for the internal memory key during the UMR operation.
