Message-Id: <1444067897-1951-1-git-send-email-pshelar@nicira.com>
Date: Mon, 5 Oct 2015 10:58:17 -0700
From: Pravin B Shelar <pshelar@...ira.com>
To: netdev@...r.kernel.org
Cc: Pravin B Shelar <pshelar@...ira.com>
Subject: [PATCH net] openvswitch: Fix egress tunnel info.
While transitioning to netdev based vport we broke OVS
feature which allows user to retrieve tunnel packet egress
information for lwtunnel devices. Following patch fixes it
by introducing ndo operation to get the tunnel egress info.
Same ndo operation can be used for lwtunnel devices and compat
ovs-tnl-vport devices. After adding the device operation
There is no need for similar ovs-vport operation. So the vport
API is removed.
Fixes: 614732eaa12d ("openvswitch: Use regular VXLAN net_device device").
