[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Jedrzej Jagielski <jedrzej.jagielski@xxxxxxxxx>

[ Upstream commit ea52faae1d17cd3048681d86d2e8641f44de484d ]

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")
