From: Roi Dayan Date: Thu, 12 Jul 2018 15:25:59 +0000 (+0300) Subject: net/mlx5e: Only allow offloading decap egress (egdev) flows X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7e29392eee7a1e3318eeb1099807264a49f60e33;p=linux.git net/mlx5e: Only allow offloading decap egress (egdev) flows We get egress rules through the egdev mechanism when the ingress device is not supporting offload, with the expected use-case of tunnel decap ingress rule set on shared tunnel device. Make sure to offload egress/egdev rules only if decap action (tunnel key unset) exists there and err otherwise.
