l2tp: purge session reorder queue on delete
Tom Parkin [Tue, 19 Mar 2013 06:11:20 +0000 (06:11 +0000)]
Add calls to l2tp_session_queue_purge as a part of l2tp_tunnel_closeall
and l2tp_session_delete.  Pseudowire implementations which are deleted only
via. l2tp_core l2tp_session_delete calls can dispense with their own code for
flushing the reorder queue.
