From ebe06875ff1f3d5257c4da7bc74a87ee9e0ce491 Mon Sep 17 00:00:00 2001 From: Hadar Hen Zion Date: Thu, 1 Dec 2016 14:06:40 +0200 Subject: [PATCH] net/mlx5e: Support adding ingress tc rule when egress device flag is set When ndo_setup_tc is called with an egress_dev flag set, it means that the ndo call was executed on the mirred action (egress) device and not on the ingress device. In order to support this kind of ndo_setup_tc call, and insert the correct decap rule to the hardware, the uplink device on the same eswitch should be found. Currently, we use this resolution between the mirred device and the uplink on the same eswitch to offload vxlan shared device decap rules. Signed-off-by: Hadar Hen Zion Signed-off-by: David S.
