ipv6: allow PMTU exceptions to local routes
[ Upstream commit 0975764684487bf3f7a47eef009e750ea41bd514 ] IPVS setups with local client and remote tunnel server need to create exception for the local virtual IP. What we do is to change PMTU from 64KB (on "lo") to 1460 in the common case. Suggested-by: Martin KaFai Lau <kafai@fb.com> Fixes: 45e4fd26683c ("ipv6: Only create RTF_CACHE routes after encountering pmtu exception") Fixes: 7343ff31ebf0 ("ipv6: Don't create clones of host routes.")
