The new dst implementation is compiled, as built-in, only if any device using it is enabled. Caching the dst for the tunnel remote address gives small, but measurable, performance improvement when tunneling over ipv4 (in the 2%-4% range) and significant ones when tunneling over ipv6 (roughly 60% when no fragmentation/segmentation take place and the tunnel local address is not specified). v2: - move the vxlan dst_cache usage inside the device lookup functions - fix usage after free for lwt tunnel moving the dst cache storage inside the dst_metadata, - sparse codying style cleanup ==================== Signed-off-by: David S.
