From c668a12c7bc92cc99de269647701b9d277f295b8 Mon Sep 17 00:00:00 2001 From: Greg Rose Date: Thu, 26 Feb 2015 16:10:39 +0000 Subject: [PATCH] i40e: Fix NPAR Tx Scheduler init Recent changes to the driver initialization have caused the BW configurations to not take effect. We use a BW configuration read and write back to "kick" the Tx scheduler into action.
