From 144d8305585a00467aaedc86d039a4ab036a9bcc Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Mon, 7 Mar 2016 09:30:15 -0800 Subject: [PATCH] fm10k: Add support for bulk Tx cleanup & cleanup boolean logic 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.
