From 3dc2b6a8d38cf6c7604ec25f3d50d6ec8da04435 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Mon, 24 Nov 2014 20:08:38 -0800 Subject: [PATCH] vxlan: Fix boolean flip in VXLAN_F_UDP_ZERO_CSUM6_[TX|RX] In "vxlan: Call udp_sock_create" there was a logic error that resulted in the default for IPv6 VXLAN tunnels going from using checksums to not using checksums. Since there is currently no support in iproute2 for setting these values it means that a kernel after the change cannot talk over a IPv6 VXLAN tunnel to a kernel prior the change.
