From 35651d6a6ba7cd83b93d3970f079ecb5061f4aad Mon Sep 17 00:00:00 2001 From: Jesse Gross Date: Thu, 1 Nov 2012 15:50:16 -0700 Subject: [PATCH] odp: Enable parsing ipv4_tunnel key. We can format ipv4_tunnel keys from the kernel but can't currently parse them. Userspace doesn't know how to do anything with this information but this support enables utilities like ovs-dpctl and ovs-appctl ofproto/trace to show useful information.
