From 9fba2b9b4f1566213a4f0cec658479d8915086fa Mon Sep 17 00:00:00 2001 From: Ariel Levkovich Date: Sun, 31 Mar 2019 19:44:43 +0300 Subject: net/mlx5: Expose SW ICM related device memory capabilities Add SW ICM related fields to the device memory capabilities structure and sw ownership capability in flow table properties. The currently supported SW ICM types are steering and header modify and the changes exposes the device memory capabilities for each of these two types. SW ICM memory can be allocated by SW and then be accessed by RDMA operations for direct management of the HW packet handling tables.
