Subject: [PATCH v3 net-next 00/15] ipv6: lockless accesses to devconf

- First patch puts in a cacheline_group the fields used in fast paths.

- Annotate all data races around idev->cnf fields.

- Last patch in this series removes RTNL use for RTM_GETNETCONF dumps.

v3: addressed Jakub Kicinski feedback in addrconf_disable_ipv6()
    Added tags from Jiri and Florian.

v2: addressed Jiri Pirko feedback
 - Added "ipv6: addrconf_disable_ipv6() optimizations"
   and "ipv6: addrconf_disable_policy() optimization"

  ipv6: add ipv6_devconf_read_txrx cacheline_group
  ipv6: annotate data-races around cnf.disable_ipv6
  ipv6: addrconf_disable_ipv6() optimization

  ipv6: annotate data-races around cnf.forwarding
  ipv6: annotate data-races in ndisc_router_discovery()
  ipv6: annotate data-races around idev->cnf.ignore_routes_with_linkdown
  ipv6: annotate data-races in rt6_probe()
  ipv6: annotate data-races around devconf->proxy_ndp
  ipv6: annotate data-races around devconf->disable_policy
  ipv6: addrconf_disable_policy() optimization
  ipv6/addrconf: annotate data-races around devconf fields (I)
  ipv6/addrconf: annotate data-races around devconf fields (II)
  ipv6: use xa_array iterator to implement inet6_netconf_dump_devconf()
