Subject: [PATCH net 5/5] i40e: Fix log TC creation failure when max num of queues is exceeded
Date: Fri, 23 Jul 2021 10:10:23 -0700	[thread overview]
Message-ID: <20210723171023.296927-6-anthony.l.nguyen@intel.com> (raw)
In-Reply-To: <20210723171023.296927-1-anthony.l.nguyen@intel.com>

From: Jedrzej Jagielski <jedrzej.jagielski@intel.com>

Fix missing failed message if driver does not have enough queues to
complete TC command. Without this fix no message is displayed in dmesg.

Fixes: a9ce82f744dc ("i40e: Enable 'channel' mode in mqprio for TC configs")
