Subject: [PATCH 4.17 27/66] net/mlx5e: Add ingress/egress indication for offloaded TC flows
Date: Fri, 27 Jul 2018 11:45:20 +0200 [thread overview]
Message-ID: <20180727093812.204381998@linuxfoundation.org> (raw)
In-Reply-To: <20180727093809.043856530@linuxfoundation.org>
4.17-stable review patch. If anyone has any objections, please let me know.
------------------
From: Or Gerlitz <ogerlitz@mellanox.com>
[ Upstream commit 60bd4af814fec164c42bdd2efd7984b85d6b1e1e ]
When an e-switch TC rule is offloaded through the egdev (egress
device) mechanism, we treat this as egress, all other cases (NIC
and e-switch) are considred ingress.
This is preparation step that will allow us to identify "wrong"
stat/del offload calls made by the TC core on egdev based flows and
ignore them.
