Subject: [Intel-wired-lan] [PATCH 4/5] fm10k: Add support for bulk Tx cleanup & cleanup boolean logic
Date: Mon, 07 Mar 2016 09:30:15 -0800	[thread overview]
Message-ID: <20160307173015.5682.15247.stgit@localhost.localdomain> (raw)
In-Reply-To: <20160307172722.5682.38580.stgit@localhost.localdomain>

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.
