From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jeff Kirsher Subject: [net 5/7] ice: Introduce ice_dev_onetime_setup Date: Wed, 24 Oct 2018 14:47:29 -0700 Message-ID: <20181024214731.26036-6-jeffrey.t.kirsher@intel.com> References: <20181024214731.26036-1-jeffrey.t.kirsher@intel.com> Cc: Anirudh Venkataramanan , netdev@vger.kernel.org, nhorman@redhat.com, sassmann@redhat.com, Jeff Kirsher To: davem@davemloft.net Return-path: Received: from mga07.intel.com ([134.134.136.100]:63765 "EHLO mga07.intel.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1727314AbeJYGNr (ORCPT ); Thu, 25 Oct 2018 02:13:47 -0400 In-Reply-To: <20181024214731.26036-1-jeffrey.t.kirsher@intel.com> Sender: netdev-owner@vger.kernel.org List-ID: From: Anirudh Venkataramanan ice_dev_onetime_setup contains a couple of driver workarounds for current firmware limitations. These workarounds are expected to go away once these limitations are fixed in the firmware. On a firmware release that has these issues addressed, these workarounds (while unnecessary) will not break anything.
