Subject: [PATCH 12/27] net/mlx5: Use timecounter_initialize interface
Date: Fri, 15 Dec 2017 13:08:27 +0530 [thread overview]
Message-ID: <1513323522-15021-13-git-send-email-sagar.a.kamble@intel.com> (raw)
In-Reply-To: <1513323522-15021-1-git-send-email-sagar.a.kamble@intel.com>
With new interface timecounter_initialize we can initialize timecounter
fields and underlying cyclecounter together. Update mlx5 timecounter
init with this new function.
