o Fix remaining sizeof problems for 64 bit machines. o Allow ``set ....'' when we have multiple links but aren't in multilink mode. o Do a TLS when we receive a ``Open'' event in ``Closed'' state, despite the rfc state transition table. This is clearly an error in the RFC as TLS cannot have yet been called (without TLF) in the ``Closed'' state. I've posted a message to comp.protocols.ppp for confirmation.

Allow random IP number allocation to peer. Validate the peers suggested IP by attempting to make a routing table entry. Give up IPCP negotiation if the peer NAKs us with an unusable IP. Always SIOCDIFADDR then SIOCAIFADDR when configuring the tun device. Using SIOCSIFDSTADDR allows duplicate dst addresses (which we don't want)!!! Allow up to 200 interface names (was 50) (now that ppp can play server properly). Up the version number (1.5 -> 1.6). Cosmetic: Log unexpected CCP packets in the CCP log rather than the ERROR log. Log unexpected Config Reqs in the appropriate LCP/IPCP/CCP log rather than the ERROR log. Log failed route additions and deletions with WARN, not TCPIP. Log the option id and length for unrecognised IPCP options. Change some .Sq to .Ar in the man page.
