Subject: [net-next 1/4] ixgbe: only check Tx queue enablement when debugging
Date: Thu, 18 Aug 2016 23:03:33 -0700	[thread overview]
Message-ID: <1471586616-64728-2-git-send-email-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <1471586616-64728-1-git-send-email-jeffrey.t.kirsher@intel.com>

From: Emil Tantilov <emil.s.tantilov@intel.com>

Following a write the TXDCTL.ENABLE bit is set only when the Tx queue
is actually enabled, which may not happen during the configure phase even
if we waited for it. Make this check debug only since this is causing
confusion with users who notice the warning in dmesg.
