From d0f6dd8a914f42c6f1a3a8c08caa16559d3d9a1b Mon Sep 17 00:00:00 2001 From: Amir Vadai Date: Thu, 8 Sep 2016 16:23:48 +0300 Subject: net/sched: Introduce act_tunnel_key This action could be used before redirecting packets to a shared tunnel device, or when redirecting packets arriving from a such a device. The action will release the metadata created by the tunnel device (decap), or set the metadata with the specified values for encap operation. For example, the following flower filter will forward all ICMP packets destined to 11.11.11.2 through the shared vxlan device 'vxlan0'. Before redirecting, a metadata for the vxlan tunnel is created using the tunnel_key action and it's arguments: $ tc filter add dev net0 protocol ip parent ffff: \ flower \ ip_proto 1 \ dst_ip 11.11.11.2 \ action tunnel_key set \ src_ip 11.11.0.1 \ dst_ip 11.11.0.2 \ id 11 \ action mirred egress redirect dev vxlan0 Signed-off-by: Amir Vadai Signed-off-by: Hadar Hen Zion Reviewed-by: Shmulik Ladkani Acked-by: Jamal Hadi Salim Acked-by: Eric Dumazet Signed-off-by: David S.
