There is a function that sets the default sockopts for udp sockets:
_netsnmp_udp_sockopt_set(), but that would set it for all created sockets.

It depends on whether or not you want the users to have to know about the
special transport. If that's ok, then a new transport that simply wraps around
the existing udp transport and sets the socket option should be fine.
If you want the details hidden from the user, then you're going to have to
defeat the abstraction or patch the library.

You are lost in a twisty maze of little standards, all different.
