Subject: [net-next 03/17] fm10k: Add support for bulk Tx cleanup & cleanup boolean logic
Date: Wed, 20 Apr 2016 23:09:15 -0700 [thread overview]
Message-ID: <1461218969-68578-4-git-send-email-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <1461218969-68578-1-git-send-email-jeffrey.t.kirsher@intel.com>
From: Alexander Duyck <aduyck@mirantis.com>
This patch enables bulk free in Tx cleanup for fm10k and cleans up the
boolean logic in the polling routines for fm10k in the hopes of avoiding
any mix-ups similar to what occurred with i40e and i40evf.
