From 341361533011945f0a7da85632662a5879233853 Mon Sep 17 00:00:00 2001 From: Tariq Toukan Date: Wed, 14 Sep 2022 10:35:04 +0300 Subject: net/mlx5e: kTLS, Use a single async context object per a callback bulk A single async context object is sufficient to wait for the completions of many callbacks. Switch to using one instance per a bulk of commands.
