  * Version:     0.7.0

+ * 070228 :     Fix to allow multiple sessions with same remote MAC and same
+ *              session id by including the local device ifindex in the
+ *              tuple identifying a session. This also ensures packets can't

+ *              (Oh, BTW, this one is YYMMDD, in case you were wondering ...)
  * 220102 :     Fix module use count on failure in pppoe_create, pppox_sk -acme
  * 030700 :     Fixed connect logic to allow for disconnect.
