Hi!

IP_TTL and IP_TOS setsockopt(2) options currently do not take
any effect on raw IP sockets (actually, everything that uses
rip_usrreqs function set).  The attached patch fixes this.

Also, I have the question.  Should we use MAXTTL constant or
net.inet.ip.ttl MIB variable, as the initial value for TTL?

Finally, if anyone has any objections, send them now.


Cheers,
