> This patch series try to unify the dst cache implementations currently > present in the kernel, namely in ip_tunnel.c and ip6_tunnel.c, introducing a > new generic implementation, replacing the existing ones, and then using > the new implementation in other tunnel devices which currently lack it. > > 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 Series applied, thanks for doing this work as it is a major improvement.
