* Fri Mar 31 2006 Brendan O'Dea <bod@optus.net> 2.1.17
* Wed Apr 5 2006 Brendan O'Dea <bod@optus.net> 2.1.17
- Fix IPCP length test to allow Terminate-Request (4 bytes).
- Send nsctl responses back using the correct source address (thanks ltd).
- Similarly set the source for DAE responses; use bind_address when
handling forwarded packets on the master.
* Thu Feb 23 2006 Brendan O'Dea <bod@optus.net> 2.1.16
- Send configured magic-no in LCP EchoReq when LCP is opened.
