[PATCH v2 net-next 0/9] l2tp: misc improvements

[James Chapman <jchapman@katalix.com>]

This series makes several improvements to l2tp:

  * update documentation to be consistent with recent l2tp changes.
  * remove inline keyword from functions in c source code.
  * move l2tp_ip socket tables to per-net data.
  * handle hash key collisions in l2tp_v3_session_get
  * implement and use get-next APIs for management and procfs/debugfs.
  * improve l2tp refcount helpers.
  * use per-cpu dev->tstats in l2tpeth devices.
  * flush workqueue before draining it in l2tp_pre_exit_net. This
    fixes a change which was recently applied to net-next so isn't
    suitable for the net tree.
