Subject: [net-next 05/15] i40e: Add drop mode parameter to set mac config
Date: Wed, 21 Aug 2019 13:16:13 -0700 [thread overview]
Message-ID: <20190821201623.5506-6-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <20190821201623.5506-1-jeffrey.t.kirsher@intel.com>
From: Sylwia Wnuczko <sylwia.wnuczko@intel.com>
This patch adds "drop mode" parameter to set mac config AQ command.
This bit controls the behavior when a no-drop packet is blocking a TC
queue.
0 – The PF driver is notified.
1 – The blocking packet is dropped and then the PF driver is notified.
