[PATCH v1 net-next 00/11] neighbour: Namespacify arp_tbl and nd_tbl.

[Kuniyuki Iwashima <kuniyu@google.com>]

The neighbour subsystem is almost ready to drop RTNL.

However, the control paths are serialised by the global
per-table lock.

This series converts arp_tbl and nd_tbl to per-netns table.

Patch 1 ~ 2 are misc cleanup.

Patch 3 ~ 6 store arp_tbl/nd_tbl to net->neigh_tables[] and
remove the global neigh_tables[].

Patch 7 ~ 8 replaces the direct access to arp_tbl/nd_tbl to
net->neigh_tables[] using new helpers.

Patch 9 ~ 10 finally replaces the global table with per-netns
table.

Patch 11 cleans up unnecessary net_eq().

Note that some buggy drivers access nd_tbl without checking
disable_ipv6_mod, so nd_tbl's extern definition is still left.

  neighbour: Remove __neigh_for_each_release().
  neighbour: Remove lock dance for neigh_update_{gc,managed}_list().
  neighbour: Remove unnecessary EXPORT_SYMBOL().
  neighbour: Remove __rcu from neigh_tables[].
  neighbour: Store arp_tbl and nd_tbl in net->neigh_tables[].
  neighbour: Remove neigh_tables[].
  ipv4: Replace &arp_tbl with arp_table(net).
  ipv6: Replace &nd_tbl with nd_table(net).
  neighbour: Clean up neigh_table_init() and neigh_table_clear().
  neighbour: Namespacify neigh_tables.
  neighbour: Remove unnecessary net_eq().
