Date: Tue, 28 Nov 2017 13:17:11 +0100 From: Jiri Pirko <jiri@...nulli.us> To: netdev@...r.kernel.org Cc: davem@...emloft.net, petrm@...lanox.com, idosch@...lanox.com, mlxsw@...lanox.com Subject: [patch net 1/4] mlxsw: spectrum_router: Offload decap only for up tunnels From: Petr Machata <petrm@...lanox.com> When a new local route is added, an IPIP entry is looked up to determine whether the route should be offloaded as a tunnel decap or as a trap. That decision should take into account whether the tunnel netdevice in question is actually IFF_UP, and only install a decap offload if it is.
