From cff6aad7af61da8d31e146610f9b4a4875301ef4 Mon Sep 17 00:00:00 2001 From: Bing Zhao Date: Wed, 2 Mar 2022 09:57:35 +0200 Subject: [PATCH] net/mlx5: remove unused reference counter In the previous implementation, a count was used to record the number of the references to a table resource, including the creation of the table, the jumping to the table and the matchers created on the table. Before releasing the table resource via the driver, it needed to ensure that there is no reference to this table. After the optimization of the resources management, the reference count now is in the hash list entry as a unified solution for all the resources management. There is no need to keep the "refcnt" in the table resource structure. It is removed in case that there is some unnecessary memory overhead.
